structure of the raw material is welded beads with small gaps between adjacent elements.Different material is available value and excellent operating characteristics.

Specifications foam

used as the foam insulation due to the low thermal conductivity.The proximity of the granules and the presence of occluded air between the components of the raw materials ensure secure detention of heat indoors.External or internal (suitable for roofs, attics, balconies) insulation of buildings using foam can significantly reduce heat loss in the autumn and winter periods.There are following these specifications foam (depending on brand):

  • density of from 8 to 25 kg / cu.m (determines strength);
  • water absorption of up to 4% (even minimally absorbs water by direct contact);
  • compressive strength of from 0.04
    to 0.16 MPa (well keeps its shape);
  • flexural strength: from 0.06 to 0.25 MPa (slightly brittle and prone to damage);
  • burning time: about 4 seconds (non-flammable);
  • vapor permeability: 0.05 mg / (h * m * Pa) (carries minimal air).

special composition of the material makes it completely safe to use.Environmentally friendly raw materials does not emit harmful particles or smells, does not require weathering before installation.High biological stability ensures long-term preservation of material: rodents, insects will not damage the foam.Fungus between the beads or between the wall and the heater was not formed.

Benefits

According to the building regulations permitted the use of foam in areas of moisture I-III and climatic regions I-V (normal, medium and low humidity).Advanced regions use insulation foam allow virtually all cities.Other advantages of the material should include:

  1. fire safety;
  2. Easy installation (possibility of independent work);
  3. low cost;
  4. wide range of different purposes by make;
  5. Large operating temperature range from -60 to +80 degrees;
  6. Light weight (can be used for old buildings);
  7. long term preservation.

Disadvantages One of the disadvantages of foam can be considered low air conductivity.Because of this particular wall can be affected, which is attached to the heater.Accumulation of steam and condensation will lead to the formation of mold, which has a negative impact on the structure of the state.To solve this problem will need to create an additional qualitative forced ventilation.

Features of foam

To study the nuances of mounting, selection of auxiliary materials (backing, glue) should examine the video tutorials on the foam insulation of facades.Particular attention should be paid to the docking and mounting plates, creating proper ventilation.

Detailed photo reports on warming buildings of different materials (brick, concrete) will help to define the rules of preparation and mounting foam.In the case of already existing insulation (for example, the old mineral wool) should immediately remove damaged material and to conduct high-quality cleaning of walls.

special mixture should be used for bonding.Select the appropriate adhesive will help to customer reviews, the description of the technical parameters of adhesive (safety, flexibility in a frozen state).Additionally fix the sheets on the wall, you can use dowels.Above the foam experts recommend installing reinforcement fiberglass mesh: it will increase the strength of the layers.Work is being completed with a heater holding finishing.
