Insulation by Izoplatom, features of thermal insulation, its advantages and disadvantages, rules for installing plates and technologies for their installation by frame and frameless method. Sheathing a house with Izoplatom is an excellent way to heat and sound insulation. Thanks to the outstanding characteristics of this material, it is possible to erect or modernize any buildings in an extremely short time. How to use Izoplat for exterior cladding of a house, we will tell you today in our article.
Features of works on thermal insulation Izoplatom
ISOPLAAT boards are made only from natural raw materials, the composition of which does not provide for the presence of any chemical components and glue. The raw material is wood fibers, which are obtained by crushing coniferous wood and then moistening them to maximum saturation with water. Then the mass is spread in an even layer and compressed by hot pressing.
Thanks to this treatment, wood fibers release lignin - the only substance that can act as a binder. The presence of this resin in the composition of the raw material eliminates the need to add glue to obtain boards of the required density. For this reason, the finished product has an undeniable environmental friendliness.
In addition to compaction, at the stage of pressing, a "carpet" of wood fibers is formed, which is then cut into products of standard sizes. The resulting slabs are 1200 mm wide, 2700 mm long and 8, 10, 12, 25 mm thick.
Then the products are sent for several hours for hot drying, after which they acquire all the necessary sound and heat insulation properties. To protect against moisture, the outer and inner sides of the plates are treated with paraffin.
A distinctive feature of Isoplat® from other types of fibrous plates is the presence of a smooth side suitable for finishing. This makes it a cost-effective alternative to traditional OSB, drywall or plywood.
Three types of Izoplat boards are used as an insulating coating: sound and heat insulating, windproof and universal products with tongue-and-groove joints. For external insulation, windproof and heat-insulating plates are used, all of them have a layered structure that provides the material with durability and strength.
The main function of Izoplat thermal insulation products is to protect the building from the cold. The thermal conductivity of such plates, depending on their thickness, is 0.053-0.045 W / m2… This indicator determines the amount of heat that 1 m passes through2 material area at a temperature difference of one degree.
Ideally, for frame construction, fiber insulation should be located between the interior and exterior trim of the exterior structures. This approach to the installation of Isoplat boards will make the energy efficiency of the house flawless. In winter, it will require few resources to heat it, and in summer, insulated walls will perfectly keep the coolness in the premises.
Isoplatom wall covering with a thickness of 12 mm has the same thermal insulation characteristics as 200 mm brickwork or 450 mm wood. As for the sound absorption of plates of this type, it should be understood that this indicator directly depends on the thickness of the products. The larger it is, the higher the soundproofing of the coating. This is especially true if this parameter is the criterion for choosing Isoplat. Using such slabs for cladding external structures, it is possible to reduce the sound permeability up to 50%.
The use of windproof panels for wall insulation has certain features. Such Isoplat products are specially designed for the climatic conditions of the North, where wet weather prevails and it is often necessary to block the wind to protect houses.
In this case, the material serves as insulation, wind protection, sound insulation, steam and hydro barrier for roofs of buildings, as well as external walls. The resistance of the windshield plates to bad weather is ensured by the addition of a waxy component to the fiber mass in the production of products. It increases the moisture resistance of the slabs, which is extremely important for the exterior decoration of the house.
Using Izoplat windproof panels, you can easily turn an old cottage into comfortable housing for year-round living. Walls insulated in this way can be plastered or equipped with a ventilated facade.
In order to distinguish windproof plates from other Izoplat heaters when choosing a material, you should pay attention to their color: on both sides of the products it is dark green. This marking is specially applied by the manufacturer solely for the convenience of identifying the type of material. The size of the windproof slabs is 1200x2700 mm, their thickness is 12 or 25 mm, the edge along the perimeter of the slab is straight.
Advantages and disadvantages of Izoplatom insulation
Plates Izoplat, being a 100% environmentally friendly material, carry their useful properties both to the enclosing structures of the house and to the people living in it. Therefore, every year more and more developers want to use this particular material for insulation of walls, roofs and ceilings.
Among the advantages of such thermal insulation are the following:
- Isoplatom wall cladding creates acoustic comfort in the space, providing reliable sound insulation of rooms from outside noise.
- Porous insulation is able to regulate the microclimate. Plates Izoplat can "breathe", drawing in excess moisture from the premises and releasing it back when the air dries out due to the operation of heating devices.
- Insulation with Isoplatom counteracts the formation of condensation and mold, accompanying it, causing diseases and immunity disorders.
- There are no chemicals or glue in the material.
- The energy consumption of this insulation is quite high. By accumulating heat in itself, the insulating layer maintains a stable temperature in the room, does not allow it to cool down quickly in winter and heat up in summer heat.
- When installing, the insulation plate is easy to handle. It is not difficult to drive a nail into such a product or screw in a screw. The material is cut effortlessly with an electric jigsaw, hand saw or circular saw.
The disadvantages of Isoplatom insulation for external cladding include the need for careful work with the material: it is rather fragile, you cannot step on the plates and drop them. The product may be damaged from pushing or any impact. In this case, it will have to be replaced or cut off.
Another disadvantage is the lack of protection of the end parts of the plates from moisture. Therefore, after mounting several products on the wall, the places of their joining must be immediately sealed with polyurethane foam, the excess of which can be cut off the next day.
Installation rules for Izoplat plates
In frame construction, Isoplat slabs serve as a material designed to close cold bridges. This must be done due to the fact that the wooden elements of the frame have a higher thermal conductivity than the insulation distributed between them (expanded polystyrene or mineral wool).
Installation of slabs on the walls or frame of the house is carried out most often in the vertical position of the products, that is, their short sides are located at the foundation of the house or its basement.
The frame elements are mounted with a 600 mm pitch. Therefore, the Izoplat plate will be installed between three profiles or bars. This makes it possible to conveniently fix it and eliminate the need for unnecessary cutting of the canvases.
The standard slab length of 2,700 mm allows for easy sheathing of walls with heights of 2, 7 m or less. If they are higher, there will be a gap between the floor and the upper edge of the sheathing. In this case, wooden blocks are installed between the frame elements from the side of the walls, fixing them at a height of 2.68 m. It becomes possible to fasten the upper part of the mounted panel with screws and build it higher with the same canvas, but shorter.
The insulating or windproof panel is fixed to the base with nails or self-tapping screws. The second method is preferable, since working with a hammer can damage the stove. Due to the fact that it does not differ in particular hardness, self-tapping screws are screwed into it no closer than a distance of 10 mm from the edge of the canvas. Otherwise, the section of the fastener may crumble.
Additional fixation of the slabs is carried out by stuffing wooden blocks over the products, which in the future will serve as the basis for a ventilated facade. At the same time, Izoplat can be fixed only in 3 places on the frame elements adjacent to the slab. To fix the products, special staples 40x5, 8 mm for a pneumatic stapler are used. When fixing boards of t. 12 mm, the length of screws and nails should be 40 mm, for boards t. 25 mm - 70 mm.
As a support for mounting Izoplat on the wall, you can use a bar with nails, half driven into it. In this case, it is fixed on the element of the lower trim of the lathing in the place of the future installation of the slab.
Isoplatom exterior cladding technology
In areas with mild climatic conditions, a single-layer Izoplat thermal insulation coating will be sufficient to insulate houses. But for regions with cold, long winters, such insulation of buildings is insufficient: it will be necessary to lay this insulation in 2-3 layers.
Preparatory work before installation Izoplat
Isoplat sheets for wall insulation can be installed either on the frame or by gluing directly onto the prepared surface. In the first case, there is no particular need for careful alignment of the walls. The frame for sheathing with slabs is made of a wooden bar with a section of 45x45 mm or more, the pitch of the racks depends on the thickness of the products used.
The installation of the bars when they are fixed to the base surface should be controlled by the building level, ensuring that all the elements of the lathing are in the same plane. In this case, the insulating sheathing will not have pronounced protrusions or depressions, which can significantly facilitate the finishing of the walls.
In the case of gluing sheets, the base surface must be carefully prepared. To do this, concrete and stone walls must be cleaned of the old peeling coating, dirt, stains and dust must be removed from them, and then the revealed cracks, chips and surface dents must be repaired with cement mortar. If necessary, they should be leveled with putty or plaster.
Surface quality control is determined by a two-meter rail applied to the wall in different directions. The gap between them should not exceed 2-3 mm.
Sheathing the house with Isoplat frame method
Isoplatom frame house cladding technology provides for the sequential execution of several stages of work:
- Marking of the general sheathing level … Along the perimeter of the house on the elements of the lower strapping, you need to draw a line with a marker, which will serve as a guide for the installation of plates. In addition to a marker, you should use a building level and a square for work. With their help, the line will turn out to be strictly horizontal along its entire length.
- Marking plates for fasteners … If further wall decoration is planned on Izoplat slabs in the form of plastering or another that does not require the installation of a frame, marks should be applied to each product with a step of 150 mm, corresponding to the fixing points of the panels to the racks of the metal or wooden frame. This marking should be applied as each subsequent board is installed.
- Installation of Isoplat panels … Installation must start from the corner of the house. The panel should be mounted with its lower end along the general marking line. The long side of the product must be aligned with the corner post of the frame. During installation, each slab must be supported and secured first in the middle, and then on both sides of it. Docking of panels with each other should not be done closely, but with a distance of 2-3 mm. Such gaps are designed to compensate for changes in the size of products due to fluctuations in temperature and humidity in the environment.
- Sealing joints … Compensation gaps between Isoplat panels must be treated with mounting frost and moisture resistant foam or silicone waterproof sealant. After hardening of any of these aggregates, their excess on the surface of the slabs must be cut off with a knife.
At the locations of doors and windows, the edges of the slabs to be mounted must exactly repeat the lines of the openings, that is, the products are fixed flush with the corresponding sides of the bars that form the holes in the wall.
Sheathing the house with Isoplatom frameless method
This method is usually used to insulate concrete or stone walls. In this case, the supporting base must be flat, and its permissible differences are calculated within 2-3 mm. This requirement is easiest to fulfill with internal thermal insulation of the room. Therefore, fastening plates for Izoplat walls by the frameless method is very rarely used when sheathing a house from the outside.
The technology of installing insulation in this way consists of several sequential actions:
- Adhesive selection … For fixing the plates in this case, a moisture-resistant and frost-resistant binder is used. They can be glue Ceresit CT190 or Baumit Star Contact, the consumption of which is 5-6 kg / m2… The package contains 25 kg of the mixture. In addition, the boards can be fixed using Macroflex polyurethane foam and its analogues.
- Glue application … It is made on the rough surface of the panel and the area of the wall to be glued. The adhesive should be applied in stripes and spread over the surface with a notched trowel. The thickness of the binder layer should be 0.3-0.5 mm. Departing from the edge of the plate 25-30 cm, you need to apply the first strip of glue, then, stepping back another 20-25 cm, apply the next strip.
- Fixing the slab … After processing with the composition of both surfaces, the product should be applied to the wall and pressed for a while, which is indicated on the packaging of the glue manufacturer. To do this, you can use a board, one end of which abuts at an angle to the Izoplat plate, and the other to the wall.
After gluing the panels, their joints must be sealed with a sealing compound, which can be used as silicone paste or polyurethane foam.
Surface finishing
After wall cladding with Izoplatom, you can proceed to their finishing. First you need to putty the joints between the plates using a reinforcing tape.
They should first be cut with sandpaper to a depth of 2-3 mm and a width of 50 mm. Then put putty on the processed joints, and then lay the reinforcing tape on it in the longitudinal direction, smoothing it with a spatula and removing excess mixture.
After a day, when the putty is dry, you can apply a continuous layer of it to the boards, which is also kept until complete polymerization. After that, the coating must be sanded, construction dust removed from it and primed with water-based paint. This will give a good white base for light painting - in this case, the dark background of the insulation will not be visible through it.
In addition to painting, a ventilated facade can be mounted on Isoplat insulation plates, using frame bars for fastening it, or decorative plaster can be performed.
