Frame houses from SIP panels are a Canadian construction technology that allows you to get comfortable housing in 3-4 weeks at quite reasonable prices. Such terms can be achieved due to the correct organization of labor, the availability of skilled workers, modern equipment and in favorable climatic conditions.

SIP panels for construction
SIP panels are made of OSB sheets, between which there is expanded polystyrene. The elements are firmly glued to each other with polyurethane glue and represent a rigid structure capable of withstanding longitudinal loads up to 10 tons per linear meter, the maximum lateral forces can reach 150 kg / m 2 . Due to the low thermal conductivity of OSB and expanded polystyrene, the heat transfer coefficient does not exceed 3.
94. This means that a panel with a thickness of 120 mm in terms of heat saving is comparable to a brickwork of 250 cm. Due to the fact that OSB panels are made from natural wood shavings, the external surfaces must be protected from harmful atmospheric influences. How and with what can external walls of buildings be finished?
Advantages of self-supporting insulated wire panels
House from SIP panels
There are several methods of finishing the facades of such buildings, each of them has not only advantages but also disadvantages. Consider commonly encountered technologies.
Table. Methods for finishing the facade of a house from SIP panels.
|Finishing method||Brief performance characteristics|
| The most successful, according to professional builders, option for finishing the outer surfaces of self-supporting insulated wire panels. The existing huge selection allows you to choose the right option, the cost refers to the budget. Plastic, metal and natural wood elements can be used as finishing materials.
| One of the disadvantages ventilated facades - bulkiness and relatively large weight of supporting structures. SIP panels are used quite often for finishing external walls. Allows you to simultaneously carry out additional insulation during finishing - a very important point for the northern regions of the country.
| External walls are lined with special facing brick in a quarter. The method is used quite rarely due to its complexity and high cost.
In addition, even during the construction of a house from SIP panels, it is necessary to provide for a large load on the foundation, which increases the estimated cost of the structure. But for all performance indicators, this option is considered the best.
| Decorative plasters can be applied for finishing slabs, but we do not recommend using them.The fact is that none of them can protect the self-supporting insulated wire panels from moisture, even the plasters react negatively to difficult operating conditions. If there is a great desire to plaster the walls, then a full range of measures should be taken to protect the plates from moisture penetration.
| The cheapest way, special materials are used for outdoor work.

During the construction of a house from SIP panels, their vertical position is constantly monitored. The surface of the slabs is flat and does not require any additional preparatory measures before finishing. These factors make the work much easier and faster. The tile is fixed on self-tapping screws, it is easy to repair it in case of critical mechanical damage.
The tightness of the joints eliminates moisture penetration - a very important factor for OSB boards. A large selection of different options allows designers to choose any option for the design of facade walls, the tile is not afraid of sudden temperature changes, is resistant to dampness and harsh ultraviolet rays.

Step 1. Measure the area of the front walls and decide on the nomenclature and quantity of finishing materials. Subtract the dimensions of windows and doors from the total area.
It is recommended to add about 5% of materials for the inevitable losses, there is no longer a need. The tile finishing technology is considered economical, the amount of unproductive waste is minimal.
This is how a house from SIP panels will look like after finishing decorative facade tiles
Step 2. Purchase materials, prepare tools. When purchasing, remember that you need to have special elements for decorating the inner and outer corners, starting and finishing profiles, etc.
The specific list of additional elements depends on the brand and manufacturer of the tile. For the installation of the battens, you can use wooden slats, boards or metal structures. The choice does not matter - neither wooden nor metal structures will lower their initial performance for a long period of time. This is explained by the fact that they are protected from moisture. In addition, the features of the fixation method contribute to the appearance of natural ventilation between the wall and the cladding.

Practical advice.It is much better to use boards with a thickness of about 20 mm for lathing, you can take unedged ones. The main thing is that the thickness parameters are maintained, the spread should not exceed ± 2 mm per linear meter. The width of the boards is between 10-15 cm. Why do we recommend boards? Firstly, such material will be much cheaper than other options.
Secondly, the process of installing the lathing will be significantly accelerated, they can be fixed with both self-tapping screws and ordinary nails. Thirdly, the boards simplify the sheathing process, due to the large width, possible errors during the installation of the battens are leveled. If additional insulation of the panels is planned, then the boards are not used for sheathing, it is necessary to buy metal brackets with a length slightly more than the thickness of the insulation layer.
Step 3. If you are afraid of high humidity, you can treat the wooden crate with an antiseptic, the brand does not matter.
All modern drugs are highly effective. You need to impregnate the boards in two layers. Lay them out on stands and apply the preparation with an ordinary brush without gaps.
Step 3. Mark the position of the battens on the walls of the house.
Work must be performed only under the level. The distance between the boards is selected taking into account the type of tiles. Each manufacturer gives its own recommendations, taking into account the specifics of the placement of fasteners, study them and strictly follow.
Installation of battens, vapor barrier
Step 4. Installation starts from the corner and is carried out in rows from bottom to top.
In the first row, each tile is fixed with four self-tapping screws with rubber washers. Self-tapping screws are sold as a set and have a protective anti-corrosion zinc coating. Monitor the position of the rows at all times. If minor deviations are found, they can be corrected during the installation of the gaps between the rows. Only it is not necessary to correct relatively large non-parallelism in one pass, each row can level about 1-2 mm of deviations.
The upper rows are inserted into the lock with the lower ones and are fixed with only two self-tapping screws to special galvanized metal elements.
Installation starts at a corner and runs in rows from bottom to top
Go to the second wall
Practical advice. If there are difficulties with the tight abutment of the locks, then they can be cut a little with a grinder. Inside, the gap will not be visible, and its presence will allow you to install the tile in the desired position.
Important! Always start decorating your home from the basement.
For this site, buy material with increased physical strength and resistance to atmospheric precipitation.
Finishing must always start from the basement

Step 5. On the upper plane of the basement row, fix a special decorative strip. It covers the fastening of the basement tiles and has a groove for fixing new ones.Some of the tiles have side fastening, which can cause difficulties during installation.
Problems arise when the vertical posts of the battens do not lie strictly in the same plane. How to solve them? Very simple. Do not reach the end of the side fasteners, move one tile a little and insert a new one into the locks. Now insert a screwdriver or screwdriver into the gap between them and tighten the self-tapping screws, move the new tile all the way to the old one.

If you are pre-insulating the walls, then first you need to prepare the crate for the heat insulator.
The distance between the bars should be about 5 mm less than the parameters of the insulation. Mineral wool or foam is used as a material. What exactly should you choose? Let's talk about their advantages and disadvantages.
One more thing - cotton wool does not emit harmful chemical compounds into the air. But this advantage is not of great importance when facing external walls. Disadvantages - high cost and extremely negative reaction to increased relative humidity. Wet wool not only significantly increases thermal conductivity, but also negatively affects nearby wooden structures. Such features require the complication of the installation technology and an increase in the cost of work.
It is imperative to install a windbreak between the mineral wool and the counter batten. The fact is that when cotton is blown with natural ventilation air flows, heat losses increase several times, which significantly reduces efficiency.
Example of laying mineral wool
A membrane is stretched over the bars and cotton wool and a counter-lath is attached
True, today there are foam plastics on sale that do not support an open fire. Fire authorities only allow the use of foam boards for facades of low-rise buildings. Another problem is that foams are damaged by rodents. It is necessary to take measures to prevent their penetration; in the case of ventilated facades, metal gratings are used.
Finishing of door and window openings. During the installation of the battens around the perimeter of these architectural structures, it is imperative to install boards or slats. The distance between the openings and the lathing depends on the characteristics of the tiles and is indicated in the manufacturer's instructions.
Window openings must be dealt with separately

Step 7. Install the window sill.
All framing elements are sold complete with facing tiles.The ebb is fixed with self-tapping screws to the crate, carefully check its position with a level.
Step 8. Fix the platbands around the perimeter of the window, if holes need to be drilled to fix them, then they are subsequently closed with plastic plugs. The joints of individual parts are sealed with a sealant for outdoor use.
Excess must be removed immediately, no need to wait until the material has completely hardened.

Installation of corners can be done in two ways: by means of new corner elements or by joining two tiles. The lathing for corner tiles should be aligned with the lathing for the wall.
A way to fit the tile to the desired wall width. We cut a wide tile and joined it with the corner elements
Example of corner decoration
When adjusting the position of the tile at the joints architectural elements have to be trimmed.
When trimming, metal plates are removed for fixation. In these cases, for fixing, it is necessary to drill holes in the plane of the tile and screw in screws into them. Subsequently, the holes are sealed with sealant in the color of the material.

This finishing option allows you to immediately additionally insulate buildings, thermal panels have an effective insulator. Advantages: there is no need to make a lathing and counter-lathing, non-woven materials are not used to protect thermal insulation materials.
Manufacturers offer a large selection of panels, each of them fully provides products with components and additional materials. The standard list includes starting, mating, finishing and joining aluminum or metal strips, corner elements.
Thermal panels with clinker tiles
To decorate the external surfaces of the self-supporting insulated wire panels, you will need a metal profile for drywall, suspension and self-tapping screws. Before starting work, you need to prepare a hammer drill, a level, an electric jigsaw, metal scissors, a cylindrical grinder (grinder), a level, a set of screwdrivers or a screwdriver.
Mark the position of the frame on the surface of the slabs. The work is facilitated due to the fact that the plates have very flat planes; nothing special is required to adjust. The distances between the vertical bearing supports of the frame depend on the type of slabs and are indicated in the manufacturer's recommendations.At the desired distance, beat off the vertical lines with a blue rope, along which the profile holders are fixed.
Attach metal profiles to the holders, use self-tapping screws for metal. Check the position of the crate again, it is very difficult to correct errors in the future.
Fixing the metal profiles
Step 3. Fix the lower starter bar. The position should be strictly horizontal.

Step 4. Install the panel into the protrusion of the starting plate, at the bottom of the panel they have a groove. Attach it to the metal profile. The next panel is fixed in the same order. During fixing, make sure that the self-tapping screws do not turn in metal profiles, choose the optimal tightening torque.

If the length of the wall of the building is longer than the length of the panels, then special joint profiles must be fixed at the joints. Most manufacturers, along with the strip, sell a decorative element for closing it, the color and structure of the element correspond to the parameters of the panels. In this place, there must be a vertical rack of the crate, keep this in mind during marking and installation.

Step 1. Take a starter bar, cut a piece about 10 cm long.
Cut a ledge and bend the piece squarely.

Step 2. Fix the prepared corner to the wall of the building. Insert the groove of the corner panel element into the projections, fix it at the top with screws. Use the same principle to mount the corner panels to the full height of the facade wall.
An example of installing a corner panel
The decoration of door and window openings is done using special additional elements. They can be made to order or purchased with a preliminary fit. During installation, pay attention to the tightness and direction of the joints, do not allow water to enter the sheathing.
Next, the openings are finished
The finishing strip under the roof can be of two types: it is fixed on the profile and a panel is inserted into the groove or fixed on it, and then in the assembly is screwed to the bar.

The most budget-friendly option for finishing facades of frame houses, most often used for auxiliary buildings.
The main disadvantages include the fragility of the coating and the impossibility of additional wall insulation. How to paint the outer surfaces of SIP panels?
Home painting technique
Step 1. Prepare the surface. The house is assembled on a timber frame, pay attention to the condition of the bars. If there are cracks on them, then they must be putty.
In addition, carefully align the joints between the panels and the framing beams. It is desirable to make them invisible, but this will take a lot of time and effort. If there is no desire and skill, then the joints can be closed with special decorative strips to match the color scheme of the paint or choose contrasting options. During painting, the strips must be covered with masking tape, which will protect the elements from paint ingress.
Cover the surfaces with a primer, the grade is selected taking into account the characteristics of the paint. The primer should not only increase the adhesion coefficient between materials, but also serve as additional waterproofing.
Step 3. Start painting the surfaces. You will have to apply at least two layers, keep this in mind when calculating the amount of materials.
It can be painted with a pneumatic spray gun, brush or roller. We recommend using a roller. Why?
Front foam plaster
The easiest way to insulate a house is to sheathe it with foam. The material is inexpensive, installation is easy to do on your own, the energy-saving effect is obvious.
And in order to protect such a sheathing from the harmful effects of the environment, you need to choose a suitable coating for it. Read more here.
There are several guidelines to follow when working with the roller.
Secondly, drips may appear. It will not be possible to eliminate dried drips with a second layer of paint; you will have to grind them off with fine-grained emery cloth. The surface of the walls will still have to be covered with a second layer of paint and it will eliminate the translucent areas.

We talked about several methods of finishing the external surfaces of SIP panels, this will help you consciously choose the option that is acceptable for yourself. And one more practical advice. Remember that finishing methods that involve ventilated facades have a negative effect on the home's thermal performance. Natural ventilation is constantly present between the wall and the decoration, warm air is removed and cold air enters its place. Do not use various thermal panels for such decoration, there will be no actual effect from their use, only the cost will increase.
