Modern private housing construction is famous for the fact that it has a large arsenal technical solutions, allowing you to make the external and internal appearance of the house the way the customer wants to see it. This judgment is also true for the choice of roof design, which is why cities have more original roofs arched type replaced the traditional gable, hip or hip ones.
An arched roof is an elegant, lightweight, ergonomic design that immediately makes the architectural appearance of the house more original, more interesting, and bolder. But the most important thing is that this roofing option will cost no more than the standard ones, if you figure out how to install it yourself.
An arched roof is a curved structure in the form of an arc, with the help of which residential buildings, industrial or administrative buildings are covered in order to protect from atmospheric precipitation, cold, wind. Previously it was believed that this constructive solution buildings with a specific purpose are more suitable - swimming pools, greenhouses, greenhouses, shopping galleries and passages. But now arched roofs are actively used in the construction of private houses, due to the following advantages:
- Original appearance. A house with a bizarrely curved roof immediately stands out visually from the background of similar buildings with a flat or.
- Resistance to wind loads. The aerodynamic, curved shape without sharp corners makes the arched roof invulnerable to strong gusts of wind, which often lead to roofing failures.
- Reduced snow load. The arch, which has a curved shape, does not retain snow masses on the slope, due to which the load on the supports and foundation is reduced.
- Increasing the volume of the room. Thanks to arched design The roof increases the internal volume of the house, which is why it becomes visually more spacious and larger.
Note! Depending on the configuration and roofing material, arched roofs can give the house both an ancient, historical appearance and an ultra-modern, current look.
Support frames
Many inexperienced developers wonder how to properly make an arched arched roof. To begin with, it is important to understand that the roof frame is the most an important part a structure that performs load-bearing and distribution functions, ensuring its reliability and stability. To construct a roof in the form of an arch, the following types of frames are used:
- Wood. Wooden frame - simple, but effective solution for the arched roof of a private house. It is quite cheap and easy to install, but is not designed for heavy weight, so it is not suitable for roofs with a large area.
- Steel. Frame made of steel pipes square section– durable, solid foundation for the installation of an arched roof, however, this is a fairly massive option, which requires the installation of a foundation and walls with high load-bearing capacity.
- Aluminum. The arched frame made of aluminum is highly resistant to corrosion, light weight, good load-bearing capacity, in addition, standard profiles can be easily assembled even with your own hands. The only drawback This option has a high price.
- Reinforced concrete. Reinforced concrete arched structures are produced for roof installation, but they are used only in the construction of industrial, commercial or sports structures with a large area.
- Frameless. To assemble arched roofs, a special self-supporting curved corrugated sheet is produced, which is installed without installing an additional supporting frame.
Important! Correct calculation of the frame structure is the key to strength, reliability, and durability of the structure. Calculations of the required load-bearing capacity are made in accordance with climatic conditions, slope and other roof parameters, taking into account the weight of the roofing material.
Types of coatings
Before you build a house with an arched roof, you need to take into account that not all roofing materials are suitable for this design. The covering for the arch should bend easily and retain its shape well, so the choice is very limited. Professional craftsmen consider the most common materials for covering arched roofs to be:
- Sheet steel. Roofing steel sheets are often used to cover arched roofs. They are quite cheap, easy to install and maintain, however, they have low load-bearing capacity.
- Profiled sheeting. Special arched corrugated sheeting is created specifically for arched roof shapes. It has a high load-bearing capacity, which is given to it by a reinforced profile, but at the same time it weighs little. Arched corrugated sheeting is available with a standard bending radius.
- Cellular polycarbonate. Another solution for an arched roof is cellular polycarbonate, having a translucency level of 80-90%. This property of the roofing material, combined with very low weight and high strength, allows you to make maximum use of the possibilities natural light in a buiding.
Please note that the possible shape of an arched roof directly depends on the chosen roofing covering. Cellular polycarbonate has the maximum bending radius, which is most often used to cover structures of this shape. In addition, this material is quite easy to install using special profiles, and also weighs little.
Installation of an arched polycarbonate roof
Translucent roofing made of lightweight but durable polycarbonate is a popular technological solution for greenhouses, greenhouses, shopping pavilions, gazebos or other elements of urban infrastructure. Installation of such structures is carried out according to the following algorithm:
- Before making an arched roof, it is necessary to calculate the load-bearing capacity of the frame and the optimal distance between the elements.
- Next, according to the calculation and drawing, a frame is made from a light aluminum profile. It is important that each arc has the same shape. To do this, first use a template.
- The frame arcs are fixed on the top trim of the house in increments of 1-1.5 meters. First, the first and last trusses of the structure are installed, and all the others are aligned with them.
- Using fixing strips, cellular polycarbonate is secured to the trusses, not forgetting to take into account the gaps for thermal expansion of the materials.
- The ends of cellular polycarbonate are protected from the penetration of moisture and dust using a special end profile.
Remember that cellular polycarbonate must be laid so that its profile is located along the bend of the arch, otherwise condensation will accumulate in the honeycombs, which will not be able to escape from there.
Video instruction
We analyze the features of the device and how to independently make an arched rafter system.
The most common forms of roofs for cottages are “hip” and “double-pitched”. This is explained by the fact that this roof shape is well known to many builders, and all stages of manufacturing are described in detail in any methodological publication.
However, many private developers would like to move away from the “clichés”. There is a growing interest in domed, semicircular and pointed roof shapes. In addition to attractive appearance, such a roof has a number of significant advantages:
- High strength and load bearing capacity;
- High resistance to strong winds;
- Snow does not accumulate on the surface of such a roof and does not stagnate. rainwater;
- Larger volume of internal usable space and ceiling height in the residential attic;
- Elements of an arched rafter system (especially if they are made in the form of trusses) can become spectacular decorative element interior decoration attics.
Thinking about how to make a semicircular roof from wood, and understanding the many advantages of a “bent” roof, many developers are put off by the high price of an arched rafter system, the complexity of its calculation and manufacture: in industrial conditions, lamellas (from which laminated veneer lumber is made), steamed to 100 °C, at high humidity(which gives the wood elasticity) are bent according to a special template, then glued together and dried in drying chambers.
Along the bend line of the beam, you can make special cuts - “to a cone” or “to a rectangle”. This simplifies the process of bending wood.
In private construction conditions, such a technological stage is difficult and economically unfeasible to repeat. And when using parts industrial production– in the form of bent laminated veneer lumber, steel and wooden curved trusses, etc. – the cost of such a rafter system increases many times over. That's why FORUMHOUSE users They offer their own, more “budgetary” methods for making arched rafters and semicircular roof rafters.
Nikofar User FORUMHOUSE, Moscow
I decided to build a frame outbuilding with a semicircular pointed roof. To do this, I had to become one person: an architect, a designer, a customer, an estimator, a “sponsor” of construction, a foreman, a technical supervision specialist and a builder. But the result was worth it. I managed to realize all my ideas. And for several hundred thousand rubles (260 thousand of which were spent purely on the “frame”) to build a house with a “pointed roof”, 3 bedrooms, a kitchen-living room, an entrance hall, a separate bathroom and a small hall on the second floor.
What the forum member ended up with can be seen in this photo.
Of particular interest are the stages of manufacturing a “bent” rafter system.
In the classical sense, this “rafter” does not have the usual rafter legs.
There are also no glued elements in it. If you look at the photographs, you can say that the rafter system uses elements borrowed from shipbuilding.
The essence of the technology used Nikofar is as follows:
- The main load is borne by the “gable truss”. In this truss, the outer radius edge is made of “frames”. “Frames” are made of short lamellas assembled in two layers and fastened together with screws.
- Horizontal “stringers” are laid between the gable trusses, running from the upper edge of the vertical wall to the roof ridge.
- In the spaces between the stringers there are spacers made of lamellas. These lamellas have an outer radius that matches the radius of the roof.
The slats were cut out with a chainsaw. To simplify and speed up the marking of lamellas, a special template was made - a semicircle of two slats and plywood 12 mm thick.
Such a template is cut to a specific and pre-calculated radius of curvature of the roof. Also, before you start making a curved rafter system, you need to make a full-size radius template. Check at the installation site whether the required radius is observed, whether everything is calculated correctly, and only after that proceed to the manufacture of the remaining rafter legs. This will allow you to avoid defects, as well as timely make appropriate adjustments to the dimensions of the rafter system and template.
If you get the hang of it, it will take you to make one “radius” lamella, including marking and selection the desired board, it took the workers about 3 minutes.
After the construction of the rafter system was completed, sheathing was installed along the roof frame. For the sheathing (to save money), instead of plywood or OSB, I used second-rate edged board- 10x2.5 cm. The step between the boards is 5 cm. Then it was mounted roof covering from ondulin.
The proposed method of making “bent” rafters and the process of constructing an inexpensive frame house for permanent residence found a wide response on the forum. Forum members also expressed their pros and cons. economic feasibility construction of such a pointed roof. They also talked about the excessive consumption of wood. Let's see how true this is:
Thanks to the arched section pointed roof, with comparable costs for lumber, internal useful the volume of such a residential attic under the arch is greater than an attic of a traditional design, as well as an attic with increased overhangs.
Nikofar drew all the above drawings not in a specialized graphics program, but using the “old” MS-paint.
The arched roof, due to its shape, can withstand very heavy loads, which the builders of antiquity knew well.
Also of great interest is the project of a house with a semicircular roof from a member of our forum crazy-tortilla.
crazy-tortilla User FORUMHOUSE
I want to build a house with a semicircular roof. According to the project, it is necessary to block an unsupported span of 11x8 meters. I'm thinking of using wooden I-beams for this. Then make OSB flooring on top and lay soft roof. There will be no attic. Help me to understand, how to make a semicircular roof out of wood.
To prepare the base for installation flexible tiles on a radius roof you can use moisture-resistant plywood or OSB boards up to 9 mm thick. Plates of this thickness bend “in place” without using special devices. To obtain the required thickness of the base, slab material of small thickness (6 mm) can be laid in two layers, with the seams of the bottom layer overlapping the top layer.
After brainstorming at the forum and disputes about the type of construction of the truss system of such a roof, a decision was made: instead of horizontal I-beams use a bent laminated wood truss. After this, the forum member ordered a farm design from the designer. The photo below shows finished drawings of these trusses.
A Belarusian company has developed a unique construction startup for the production of houses with unusual architecture. Their project for a low-rise building has already become a laureate of a national architecture competition and a winner of Active House 2017 in the category best design. Tamago 115, which has a rounded roof instead of walls, is not only a product of architectural thought. The project is based on an invention that allows the construction of energy-efficient buildings of dome, tent and hemispherical shapes. We met with the creators of Tamago and found out why they call it “an antibiotic for construction,” when they will build a prototype and how much such housing will cost.
Another wheel has been invented
It all started with the fact that Konstantin Urbanovsky, a designer and businessman in one person, figured out how to make a pointed arch (represents a figure of two semicircular arches intersecting at a certain angle) from two prefabricated wooden beams. For what? So that it is possible to build buildings with a domed roof without the use of special equipment.
The main part of the technology is the UrbanBlock elements from which the beam is assembled. They are composite elements made of moisture-resistant plywood. Each lamella is cut on a machine and has a small radius. The slats are assembled into blocks and fastened with metal pins and bolts. It turns out a detail small size, weighing about 20 kg. These blocks are assembled into a “tenon and groove” into a radius (“bent”) beam of the required length. If the beams are joined, the required arch is obtained. The sizes of the blocks are unified, and, in fact, this is a constructor. Serial connection elements allows you to create yourself load-bearing frame Houses.
Unlike Russian domed houses under trademarks“Dobrosfera” and “Skydom”, which are assembled from rectilinear elements, structures made from UrbanBlock are devoid of the main drawback - visible “ribs” of the structure.
Dome from "Dobrosphere"
It was decided to patent the development of Konstantin Urbanovsky. It turned out that the invention was unique and no one in the world had ever thought of such a thing. “It’s like inventing a wheel,” jokes Yana Urbanovskaya, founder of the young company Tamago. — Now the blocks have the status of an invention, we are engaged in patent protection in 151 countries, as well as obtaining international certificates. They decided to test the technology on small architectural forms - in the spring of 2017, a gazebo was assembled near Gomel next to the experimental production. On it, the inventor's team studied the possibilities of the design. She performed very well.
Gazebo from UrbanBlock
— Next we developed architectural project gazebo, which was based on these pointed arches,” says the company’s general director Dmitry Alkhimovich. — The result is a very reliable and attractive design. As a result, we realized that this promising direction, and registered the company Tamago (translated from Japanese as “egg”). We continued to work on the architecture and study of the application of UrbanBlock technology. It turned out that they are practically limitless. You can build buildings of absolutely any shape: hemispheres, domed, conical, tent-shaped buildings, combinations various forms and sizes.
House project for 76 square meters
The project has several directions. The first is private housing. This includes projects of houses, baths, gazebos. The second is objects for the urban environment. Tamago offers innovative solutions for modernizing urban facilities. For example, we already have options for add-on attic floors on the roofs of Khrushchev buildings.
A separate area is facility projects Catering. It is worth noting that the interest in the project is serious - the famous architect Lev Agibalov works on the development team.
House in a container
The development of the idea is to create a factory production of house kits that can be sent to the client in a container. That is, a person orders a house, it is manufactured, the selected options are added and sent. It is assembled on site by turnkey installers.
Project Tamago 115
A house kit is a real construction kit with a specific set of parts. All elements are numbered and indicated in the assembly instructions. There is no need to cut anything or buy more. After assembly, all that remains is waste in the form of packaging. Ordered, assembled and live - the set is complete, with all communications, finishing and even built-in furniture.
House area - 115 square meters
“There are examples of the implementation of such an idea in the world, but they are isolated,” says Dmitry Alkhimovich. - The problem is that traditional house It is assembled from long and large-sized elements, so it is sometimes physically impossible to load it into a container. Our house kit can be called small-piece, and when disassembled it fits compactly into a sea container. A unified element (UrbanBlock) makes it easy to calculate required amount for the ordered frame with an accuracy of one. The modular dimensions of the elements - 600−1200 mm - allow installation manually without using lifting mechanisms, which significantly reduces installation costs.
The creators call their project an “antibiotic against construction.” — As soon as a person says “I want a house,” he immediately becomes a participant in a quest in which he must first find an architect, then communicate with the builders, periodically swear for missed deadlines and the quality of work, and get upset about the ever-increasing estimates. Sheer stress. Our product allows us to bypass all these people. I just came and, like in a car dealership, chose the one that was suitable from several projects, ordered the necessary options: roofing - shingles, tiles or metal, color gray, white or any other, furniture. Builders are needed only at the stage of making the foundation. Assembly is carried out by certified installers. Depending on the size, the house can be assembled in 2-4 weeks. And this will already be a completely finished housing.
When will the first house be built?
Today, the team of a construction startup is working on the implementation of a house according to the Tamago 115 project. All stages of production and assembly will be worked out on it - work is now underway to create all technological maps. To bring house production to production, every detail and action needs to be described.
The presentation of the house should take place in August 2018 in Milan. The site for it has already been chosen - in the Molodechno district on the banks of the Udranka River, in a picturesque place near the forest. The prototype will be made from a Swedish insulated slab (although it could also be built on a cheaper pile foundation).
In-line only mass production makes it possible to reduce costs. The house will not be cheap because high-quality materials and high-tech technology are used in its assembly. engineering equipment. New technologies will allow you to achieve high energy efficiency at home, thus reducing utility costs to a minimum. House of the future, gadget. This house should be a reflection of rationality.
— Today, a completed Tamago 115 house is priced at 1,200 euros per square meter, says Yana Urbanovskaya. — And this price is normally perceived by potential customers in Estonia, Poland, Germany, Finland and Russia. However, this cost can be realistically reduced to an acceptable 500-600 euros during industrial production.
Active, energy efficient
Except highest awards national architectural competition, the project already has international success - it won the Active House 2017 competition (Active House is an international alliance promoting energy-efficient technologies) in the category for best design.
— Next fall we are expected at the Milan Active House exhibition, but already with ready home, says Dmitry Alkhimovich. — To win this competition, we need to assemble a house that will meet the highest European energy efficiency criteria.
The developers claim that their houses are capable of producing more energy than they consume. This is possible thanks to the use energy efficient technologies and the architecture itself.
— Everyone knows that the smaller the area of cooled planes in a building, the less heat loss it has. In this regard, domed houses seriously outperform traditional rectangular buildings with a triangular roof. Their energy consumption is at least 20% less due to the architecture alone.
It is planned to equip the houses with supply and exhaust mechanical ventilation with a recuperator, an air-to-water heat pump for heating and photovoltaics on the roof for generating electricity. Engineering solutions The newest ones will be used, taking into account their development in the near future. That is, they will not become obsolete in the next five years.
High energy efficiency indicators are achieved by a solid layer thickness mineral wool insulation in the walls and roof of the building - 30−35 cm.
Differences from an ordinary “framework”
— If we superimpose the projections of a traditional house and Tamago 115, we see that effective area they are almost the same,” Dmitry Alkhimovich explains the difference. — But if we compare construction volumes, the number building materials and types construction work, then for a vaulted house these figures are 15-20% less. The fact is that the arched structure does not require internal load-bearing walls; the placement of partitions inside the vaulted shell is free. Its design does not have roof overhangs, Mauerlats, drainage system, roof connection units and load-bearing walls. This is a significant saving in materials during construction. load-bearing structure. There are no costs for finishing the facade.
To build a frame house, more materials will be required for a post-and-beam structural system, plus struts, stiffening diagonals, beams... If we set a goal and build a Tamago using similar materials which are used for budget frames - 15 cm of insulation, cheap bitumen roofing, budget window systems, then the cost of our house will be even lower. But we are not going to build cheap houses and compete with manufacturers frame houses We don't plan.
Who's new?
The developers from Tamago say that in our country they are interested in the new architectural form, they like the houses, but they don’t want to become “pioneers” en masse.
“There is a stereotype of what a traditional house should look like, and it’s difficult to step over it,” says Dmitry.
- But we already have our first Belarusian customer - he will build a house in Tarasovo near Minsk. His site is on a mountain with a height difference of 10 meters. So “Tamago” will be visible from afar.
In addition to houses, the production of gazebos will also be established - there is already a demand for them.
Tamago at the Budprogress exhibition
However, it cannot be said that the manufacturer of domed houses is counting only on Belarusian customers. Tamago is initially aimed at the European market - there is a demand for such architecture there. The company plans to enter our market as a European brand.
— Now in the country there are no conditions to engage in production and design of houses for our market. So we'll start there and then come here. UrbanBlock elements will be produced in Belarus, and they will be supplied to dealer and logistics centers in Europe (the first is planned to be created in Estonia). There they will be equipped with materials and equipment from manufacturers who operate in the dealer's market. The Tamago project received approval from the professional community. Now, to implement the plan, the developers unique technology looking for an investor.
Hobbit Hall in Russia from the Architectural Bureau of Roman Leonidov.
Small house, whose area is comparable to a Moscow “kopeck piece”, Roman Leonidov came up with as one of the options for expanding his dacha near Moscow. A spacious house has already been built on the architect’s site, and a small separate house was intended for the sunny lawn in front of it - the architect has been drawing various options for its development for some time.
An individual residential building for permanent or temporary residence of a family of three is a single volume, including an entrance hall, a bathroom, a kitchen-dining room and two bedrooms. From the dining room there is access to a terrace covered with a landscaped canopy. There is a storage room adjacent to the ends of the house. gardening tools, accessed from the terrace. The house has an important feature: every room is illuminated with natural light. Structurally, the building is a simple frame of bent laminated beams. The walls do not bear any load and are made of frame structures, filled with thermal insulation or sound insulation (for internal partitions).
Name: Hobbit Hall
Location: Moscow region, Russia
Architecture: Architectural Bureau of Roman Leonidov
Total area: 45 m2

Today, among the roofing structures familiar to seasoned craftsmen, the arched roof has taken a strong place. This roof design not only makes the house original and interesting, but also protects it from excessive wind loads. In addition, it is the arched ceiling that makes it possible to let in maximum light into the room if you choose transparent polycarbonate as the roof. Below are the advantages and disadvantages of such a domed roof and the principles of its installation in the material.
The use of arched roofs is widespread throughout the world today. Now in Russia they have begun to introduce such a design into the architectural field. In particular, such a roof is justified at the following facilities:
- Swimming pools and indoor sports grounds;
- Stop pavilions and shelters for transport;
- Greenhouses and conservatories;
- Arched country house;
- Capital buildings, such as powerful hangars, production workshops, etc.
Important: by the way, frameless roofs from metal profile. Such structures have greater rigidity and strength, which allows the installation of large rooms without the use of a complex rafter system.
Pros and cons of a semicircular roof
It is worth knowing that arched roofs carry a lot of advantages both for the house itself and for its owner. Main positive points such an arcuate ceiling are:
- Reducing the wind load on the roof of the house. That is, moving along a sloping roof, the wind does not experience resistance, which means it does not tear off the roof and does not loosen the rafter system.
- Unhindered descent of snow crusts from the roof. This point is important, since precipitation in the form of snow has an extra pressure to the ceiling.
- The ability to fill the room with natural light (provided that a transparent roof is used).
- Significant savings attic area. The absence of a complex rafter system ensures this.
But the semicircular roof also has some disadvantages. These include:
- Some complexity of installation. Especially if the master decides to make the load-bearing frame from wood.
- It is impossible to use any material you like as a roofing material.
Materials for covering the arched roof covering
As a rule, lightweight roofing materials that have a certain elasticity are used to cover roof arches. In particular, the following can be used as roofing:
- Galvanized steel sheets. Such a material, with its flexibility, is capable of simultaneously forming both a coating and a load-bearing rigid frame. Moreover, galvanized steel is resistant to corrosion.
- Plastic rolled slate. The coating is made of polymers and has excellent elasticity. This roofing material has smooth surface and a strong structure, which allows the master to use this material as an arched one.
- Arched profile flooring. In this case, the coating has the structure of a standard corrugated sheet. The only difference between these two types of coatings is their shape. The arched one already has an arched shape. Its advantage is that such material can be mounted on the roof frame in whole fragments.
Important: arched corrugated sheeting must be ordered from the manufacturer according to the parameters of the arched roof (span width, height of its walls and arc height).
- Glued beam. With careful installation and the correct profile, you can make a wooden beam roof. And although this option is not beneficial from the point of view of durability, from an aesthetic point of view such a roof looks environmentally friendly and attractive.
- Drywall or plywood. The materials will need to be covered on top with any roofing material type bitumen shingles etc.
- Light-conducting coatings(polycarbonate). Today it is the most popular for covering arches.
Roof frame materials
As for the materials to create the roof frame, a variety of different ones can be used. However, they should be divided into materials for use in capital industrial construction or for use in private work. So, for capital construction you can use:
- Reinforced concrete. To install such arches, complex special equipment is required, and the work will be very labor-intensive. Therefore, private craftsmen do not work with such material.
- Frameless profile sheets. It was written about them above that such material simultaneously performs both the function of a rigid frame and the function of a roofing covering.
In private construction, for the arch frame you can use:
- Wooden arched rafters. Creating such roof elements is within the capabilities of a carpenter. Or you can order such rafters from a carpentry workshop. Most often they look like arcs or half-arcs glued together from thin boards.
- Metal steel profile (square pipe). Durable and load-resistant material, but requiring some effort in bending the profile.
- Aluminum pipes. Perfect option for the arched roof frame. Aluminum is not subject to corrosion, is quite simple to work with and is easy to construct a frame. And when such legs are reinforced with spacers, the roof will be able to withstand any roofing material.
Important : pipes can be used to construct an arched greenhousesPVC.
Do-it-yourself arched roof on an aluminum profile
To build a semicircular roof with your own hands, you need to prepare aluminum pipes with a cross section of 5 cm and a length of 5-6 m. And to cover the roof in our case, we will take translucent polycarbonate of any shade. But it is worth remembering that although such a coating is modern and attractive, it is still better to use it for installing a canopy roof over a car, a pool roof or the roof of an extension. Since in the summer indoors It will be very hot under such a roof.
Important: polycarbonate tends to expand when heated under the sun. Therefore, when attaching covering sheets, it is necessary to leave a technical gap for the expansion of the roof.
Roof arc calculation
- To calculate the length of one arc and its radius, you need to take a sheet of graph paper and plot on it on a scale the width of the arch span (the distance from one wall of the house to the other) and its desired height above the span.
- Having measured everything and received the data, they are transferred to a sheet of graph paper.
- Now, in the center of the span in the diagram, we install a compass and, resting its second end with a pencil on the edge of one wall according to the diagram, we draw an even circle.
- Inside the circle you need to draw an even hexagon.
- The resulting lengths of the sides are on scale and will be the lengths of one arc, which will have to be added. In our case, for an arched roof, we will add three such lengths.
Important: the arcs of the arch can be made not from a single pipe, but from its parts. In this case, two half-arches can join at the top of the arch, forming a steeper or less steep bend.
Frame installation
The pipes must be bent using a special bend, first making cuts on the profile. It is important to remember that the more notches there are on the profile, the less steep the bending radius will be. And accordingly, the fewer notches, the larger the bending radius will be. The notches on the profile must be placed with the same spacing.
- The resulting arcs are attached with special brackets to a wooden Mauerlat. And they strengthen the structure with special stiffening ribs. You can use wood or a metal profile for this.
- The sheathing is attached along the entire perimeter of the arcs installed in increments of 50-70 cm. For polycarbonate, the lathing pitch can also vary within 70 cm. But it is better to make it equal to the width of one sheet. This will make installation of polycarbonate more convenient.
- When attaching roofing sheets, it is necessary to make holes in them for self-tapping screws in advance. Moreover, the holes should be several mm larger in order to expand the coating.
Important: to install polycarbonate, you need to use special self-tapping screws with thick washers and decorative covers.
- The roof gables are covered with any comfortable material. The one from which the house box is built will look beautiful.
Advice: if you are not confident in your abilities when calculating the parameters of the arch, then use the services of professionals or at least use a special program to calculate the parameters of the arch.
