Scope of foam
As it turned out, this material is used not only for finishing walls and ceiling of buildings, but also for insulation of equipment( including refrigeration).However, everything in order. First of all, it should be said that the foam is used as a heater for the foundation, pipeline, walls, roof. For example, in modern foundations it is used in the form of a fixed formwork.
Plates are laid in one or more layers and poured with concrete. This ensures that the structure is protected from freezing.
Also used polystyrene, as a heater between the walls. It allows you to achieve significant heat and sound insulation. The coating is fixed with cement mortar, mastic, glue. If the foam wall panels were mounted indoors, they must necessarily be protected with hypocarcarton sheets. In the case when they were fixed from the outside, they are protected by a layer of decorative plaster. If the foam is laid on the floor, then a concrete mixture is applied over the top or a wood plate is fixed.
Excellent foam for both heat insulation of the pipeline( water supply and sewerage), telephone lines, ventilation ducts. Thanks to it you can lay pipes at a much smaller depth. This allows you to reduce the amount of excavated soil.
Plus, it allows you to give the designs almost any shape, and this expands the functional fitness. The foam is also used for the finishing of refrigeration equipment, storefronts, warehouses, as this material provides excellent indicators for moisture absorption and thermal conductivity.
Properties of polystyrene
Polyfoam is not just so widely used in construction. The fact is that he has a number of advantages that allow him to apply it in many areas. So, let's enumerate the main:
- This is an extremely light material, because it is simply mounted, conveniently mounted and installed.
- Does not release any toxic substances during the operation of .That is why it is used even in the food industry for food packaging.
- Is a good heat and sound insulator. It is used even in the harshest climatic conditions.
- It is not susceptible to the development of microorganisms in it, therefore no additional treatment with antiseptic materials is required.
- Can easily be used in conjunction with other inorganic materials, such as cement, sand, lime, concrete.
- Has high resistance to high mechanical loads .Its compressive strength is from 0.05 to 0.16 MPa.
Warming walls with foam: several tips
Wall insulation - polystyrene - is attached to a pre-prepared surface. But first it is necessary to select it for some parameters( in terms of thickness and density).The average thickness varies from 25 to 150 mm, and the density varies from 25 to 50 kg / m3.The choice of these parameters depends on what characteristics of the thermal insulation you want to achieve. For example, it is worthwhile to know, a foam plastic with a density of 25 kg / m3 and a thickness of 50 mm is commensurable with the masonry in one brick( 250 mm).
After the material is selected, proceed to the installation itself. This requires dowels and special glue( sold in stores).To impose foam plates it is necessary first on those walls where windows and doors are least located. It is best to start fixing the material from the bottom corner. Mount it can be using glue applied to the back side and dowels( an average consumption of 5 pieces per 1 sq. M.).Joints are covered with the same glue.
At the last stage, an isothermal film is fixed using dowels. Above it is a crate and siding. In the event that you intend to plaster the wall, you get a special composition for the foam.
