How to fix a profile for a siding? Distance between profiles for siding

To obtain a perfectly flat surface of the facade cladding, a siding needs a reliable and durable frame capable of withstanding the weight of the entire structure and dynamic loads. It is easier to assemble the crate more easily than to level the foundation for the installation of the coating. Its installation and cladding with finishing material must be carried out in compliance with the rules on how to fix the profile for the siding.

In addition, when finishing all try to insulate the house and ensure the internal ventilation of the facade.

Which material to choose for the frame?

Among the other materials, the galvanized profile for mounting the siding took the leading position, thanks to such qualities as:

• Corrosion resistance;
• High strength;
• Fire resistance;
• Convenience of transportation and installation;
• Ease of processing and quick installation;
• Low cost;
• Non-waste;
• durability.

For skeletons under the lining, wood is also used, but it is not so stable when decorating the facades, as metal, because the finished structure is subject to rain, sun and wind all year round.

To qualitatively cover the walls, you need to properly prepare the frame. For this, it is necessary to properly observe the technology, since the lath performs three functions at once:

• Wall alignment;
• Keeping heat insulation and cladding;
• Ventilation of the facade.

Siding accessories

The supporting P-shaped profile for mounting the siding is made of galvanized metal with dimensions of 60x27x300 cm. The thickness of the sheet steel reaches 1 mm, which provides high strength.

Due to the high price, many apply profiles for drywall, the reliability of which is lower, but they can withstand the weight of the siding with a heater if light lining panels are used, and additional reinforcement with jumpers is used.

The profile of the battens is mounted in an upright position if the siding panels are horizontal. The distance between profiles for the siding is 40-60 cm.

If the cladding panels are made of heavy material, the interval between the posts is reduced to 25 cm. Double corners are installed on the corners. The frame is supported by U-shaped suspensions, fixed on concrete walls with dowels, and on wooden ones - self-tapping screws. Their number is determined by the distance between the points of the support, which is 60-80 cm. If significant dynamic loads (winds) are assumed, it can be reduced. Instead of hangers, you can use self-made consoles made from pieces of the profile. The frame can also be attached using retractable brackets and guides.

The distance between the profiles for the siding under the socle, located horizontally, is 46 cm (the height of the panels). The frame is reinforced by vertical bridges. Often a metal profile for siding is used under the socle, as it is more durable and resistant to atmospheric influences.

To fasten the profiles to the hangers, short metal screws are used. Plates of insulation are fixed with dowels.

The metal frame is installed in three stages:

• Preparation of walls;
• Base surface marking;
• Installation of profiles.

Each stage is important, since the design has significant weight and wind load. Here you can not save on materials.

Preparing for wall decoration

1. Creation of free space for work near the house and construction of scaffolding.
2. Removal of disturbing objects: shutters, platbands, gratings, drain pipes, branches of plants.
3. Restoration of worn surfaces: replacement of peeling plaster, old boards, parts of masonry, sealing of cracks and chips. Large cracks are strengthened by locks of metal profile.

Heater

Common types of thermal insulation under the ventilated facade are mineral wool, foam and ecowool. Polyfoam is convenient for installation, has good technical characteristics, but has low vapor permeability and serves no more than 15 years. Minvat should be taken in the form of semi-rigid slabs, as rolls can slip over time. Ecowool requires special equipment and it is advisable to use it for internal insulation of dry premises.

The heater is laid in three ways.

1. Pasting on the wall before installing the battens.
2. Stacking between the pillars of the crate.
3. First, the second installation is carried out, after which the perpendicular installation of the next crate is carried out from above, with the laying between the profiles of the next layer of insulation. The method is the most expensive, but effective, since the joints between the thermal insulation plates are overlapped by the top layer.

The insulation is retained by profiles, glue or plastic fungi.

Mounting the frame

One of the most common ways of installing the frame is as follows.

1. Fastening of suspensions with the help of dowels or self-tapping screws. One support profile requires at least three fixtures. The upper and lower supports recede from the ends of the racks by 15-20 cm.
2. Mounting of upper and lower guide profiles PN 28x27. It is important to set them according to the level strictly horizontally. From the correct installation of the lower profile depends on the location of the siding. From the blind there is an indentation of 2-3 cm. For the puddled soil, the distance increases. Under the load-bearing profile, a free stroke of 0.5 cm is provided.
3. First of all, there are load-bearing stands on the corners of the house. For this purpose, the PP 60x27 profile is made doubled, by joining the slats at a right angle with screws.
4. The supporting profile is cut to the required length or is built up by means of a joint fixed with screws. In order not to weaken the frame in these places, the bars are placed with a successive alternation of the connection from above and from below.
5. Vertical racks are set in the guides and fastened with suspensions, with the "whiskers" covering on both sides. Before fixing them with self-tapping screws in the upper and lower guides, installation by level, and then fastening to the suspensions. To prevent scratches in the wind load on the frame for each end, plastic liners are installed.
6. On the perimeter of all the openings. If necessary, the racks are additionally fastened with transverse profiles. To do this, you can use trimming, so that the technology is non-waste. The shortest pieces go to make homemade hangers, which are more powerful than branded ones.
7. The base of the house is also siding. For the pile foundation, it performs the function of the vial, closing the base. The distance between the horizontal profiles is selected according to the size of the liner, and the gap is from the thickness of the insulation. Under vertical joints of siding elements vertical cross-members are made from the profile.

Calculating the amount of cladding

Before fixing the profile for the siding, you must first determine its number. First, the area of the skin is calculated. For this part of the house are divided into simple geometric figures and the amount is added to 10%.

Dimensions and methods of panel connections

When choosing a vinyl or acrylic profile for siding, the dimensions vary between:

• Length - 2,5 - 4 m;
• Width - 20 - 30 cm;
• Thickness of the sheet - 1 - 1.2 mm.

There are different profiles for siding (photo below): a herringbone, a shipboard (bar), a block house (log).

To cut the siding you will need an electric jigsaw, a hacksaw, a knife, a Bulgarian with a cutting disc.

Panels are connected with each other by lapping or locking. This is done carefully, making efforts, while the upper and lower fastener elements do not converge. The connection must be free, without interference. Otherwise, the panels may bend under temperature deformation. Do not violate the horizontal, which worsens the appearance of the facade.

Setting up a profile for a siding

1. The lower level is defined. To do this, along the entire perimeter of the building, the lower line (above the blind area by 3-4 cm) is drawn.
2. The starting profile for the siding is set at the marked level and fixed with self-tapping screws. Between its individual sections a gap of 6 mm is left.
3. The outer and inner corner elements are mounted below the edge of the starting strip by 6 mm. Above left is a place for installation of soffit - panels for covering the bottom of pediments and cornice roof overhangs. The corner piece must be free to hang on the fasteners. Screws are screwed in increments of 20-40 cm. Docking of the parts of the corner pieces is done by a 2 cm overlap. For this purpose, the inner part of the part is sawn and the front part remains.
4. Lining the openings is as follows:
   A) laying aprons waterproofing;
   B) fastening of platbands or J-profiles;
   C) connection of profiles.
5. The first panel of the facade is inserted into the corner and into the starting profile for the siding. Technological indentations for thermal expansion in warm weather are 6 mm, and in cold weather - 9 mm. The jointing is done overlapping or using H-profiles. The rest of the siding is mounted in the same way. Mounting is from the middle to the edges.
6. The last panel should be mounted only when the final profile for the siding is installed. It looks like starting, only a little thinner. At the end of the installation, cutting the last panel is necessary. Strips are also cut off when installing under windows.

Installation of the gable facings

Facing the pediment should be done the same way as fixing the profile for the siding. The front along the perimeter is covered with a starting profile or for internal corners. Panels are attached similarly to wall panels. Only each element is cut at an angle and inserted into the lock of the receiving profile. There are also technological gaps of 6 mm.

Helpful Tips

1. The fastener is screwed into the center of the holes on the panels.
2. The fastening of the fasteners should not be dense, so that the lining does not warp during temperature deformation.
3. Panels are attached from left to right with a strictly horizontal position.
4. When installing the siding, it is necessary to leave technological clearances.
5. Fastening of panels is made only through special holes. It is not allowed to drive nails or screw self-tapping screws through siding material.
6. The lining of wooden houses is made only after shrinkage.
7. The physical properties of the cladding depend on which profile for the siding is used. At a temperature below -10 ⁰ С, vinyl siding loses its plasticity and can crack.
8. When installing the panels are placed freely, without interference.
9. Fasteners and metal parts used in house paneling should be reliably protected from corrosion. Otherwise, the fastening will be unreliable, and rust stains will appear on the lining.
10. Sometimes the siding panels are fixed vertically. Then the crate under them should be placed horizontally.

Conclusion

Correctly executed skeleton will allow siding to be located in one plane. The panels must be installed without interference and with process gaps. Then the temperature deformation does not lead to its buckling.

Accurate compliance with the instructions on how to fix the profile for the siding, taking into account the creation of the necessary strength and features of the materials used, will allow you to perform the work with your own hands.
