In what areas to use insulation for walls - foam ?

Scope foam

As it turned out, this material is not only used for the walls and ceilings of buildings, but also for insulation of equipment (including refrigeration).However, about everything in order.First, let's say that the foam used as insulation for foundation, piping, walls, roofs.For example, in its modern foundations are used as permanent formwork.

Plates stacked in one or more layers and filled with concrete.It provides protection against freezing construction.

also used foam as insulation between the walls.It allows you to achieve significant thermal and acoustic insulation.Fastened coating using grout, mastic, adhesive.If wall panels of foam mounted inside the room, they must be protected by sheets of giposkartona.In the case where they are fastened on the outside they are protected by a layer of plaster.If the foam is laid on the floor, then applied on top of the concrete mix or fix the wood board.

Excellent foam and insulation for pipes (water and sanitation), telephone lines, ventilatio

n channels.Thanks to him, you can lay the pipe at a much shallower depth.This reduces the amount of excavated soil.

Plus it allows you to make designs almost any shape, and it extends the functional fitness.Use foam for finishing refrigeration equipment, shop, warehouse, because this material provides excellent performance on moisture absorption and thermal conductivity.

Properties foam

Foam wonder so widely used in construction.The fact is that it has a number of advantages which allow its use in many areas.So, we list the main:

  • This extremely lightweight material, because it is easy to install, convenient to attached and installed.
  • Does not emit any toxic substances during operation .That is why it is used even in the food industry for packaging foodstuffs.
  • is a good thermal and sound insulator.It is used even in the most severe climatic conditions.
  • not subject to the development of microorganisms in it, so do not require any additional treatment antiseptic materials.
  • can easily be used in conjunction with other inorganic materials such as cement, sand, lime, concrete.
  • has high resistance to high mechanical stress .Its compressive strength is from 0.05 to 0.16 MPa.

foam insulated walls: a few tips

Insulation for walls - foam - is mounted on pre-prepared surface.But first is to pick it up on some parameters (thickness and density).The average thickness ranges from 25 to 150 mm, and the density - from 25 to 50 kg / m3.The choice of these parameters depends on what characteristics of thermal insulation you want to achieve.For example, it is necessary to know, with a density of foam 25 kg / m3 and a thickness of 50 mm is comparable to the masonry in a bricks (250mm).

Once a material is selected, proceed to the installation itself.This requires a special glue and dowels (sold in stores).Overlay foam boards must first be on those walls, where less than a total of windows and doors.It is best to start to fix the material with the lower corner.Attach it with glue can be deposited on the back side and dowels (an average consumption of 5 pieces on 1kv.m.).The joints smeared with the same adhesive.

At the last stage of securing the insulated film with dowels.Above it is a crate and siding.In that case, if you intend to plaster the wall, then it acquired a special composition for the foam.
