Foam to insulate the cellar : Is it safe ?

Features premises

Each building has a basement - the space between the ceiling and the ground.It can be quite a comfortable height for the device in its economic purpose room.The height depends on the size and height of the foundation plinth.On average, it is equal to two meters, so do not use this space simply irrational.

known that the temperature at a depth of a stable performance throughout the year, but it is far from optimal.To bring it to the norm, it is necessary to insulate the basement.This will not only benefit from the use of the basement, but also reduce the cost of heating the building.Insulate the basement can be a variety of ways, but the most effective is the outer insulation.

With this method the material is mounted on the outside, thereby preventing freezing of the walls.For internal insulation of insulation material at the joints and walls will be formed condensate, which will ruin the entire coating.Therefore it is necessary to do a thorough waterproofing the entire surface of t

he walls.Also, the insulation material itself must have a good moisture transport, so the foam - a great option for those purposes.

Important!If you do not do waterproofing, any, even the waterproof material, quickly come into disrepair.

all "pros" and "cons" of the material

deciding to make foam insulation of the basement, you need to know about all the pros and cons of this material to use it with maximum efficiency.To begin, consider the advantages of:

  • This material is an excellent heat insulation;
  • very light weight, which gives a minimum load on the foundation and walls;
  • inexpensive compared to other materials.This factor is especially important when insulation of the basement, because this area of ​​the room is large, and therefore need a lot of material;
  • When exposed to moisture does not change its characteristics;
  • Material ten centimeters thick replaces the brick wall thickness meter.

Now look at the disadvantages:

  • If used for external insulation foam, it heats up and emits an unpleasant odor;
  • low fire resistance, light up almost immediately and combustion provides life-threatening substances;
  • This is not the most environmentally friendly insulation.

Important!The foam can be used only with high fire safety premises.Taking into account all these characteristics, it is possible to conclude whether the foam suitable for insulation of the basement in each case.

How warm the cellar foam

For installation is best to use a foam density of 25.Along the edges of desirable quarters, which will facilitate the docking of dense sheets, even if the attachment is minimal.Be sure the first waterproofing layer should be, which is placed on the prepared surface.foam sheets are attached with an adhesive composition.

Once the entire surface is lined with foam, on top of cement is fifty millimeters thick.To screed had good strength, is the reinforcement mesh with a mesh of 5 mm.For screeds can be used cement grade M 100 . Note!Cement screed to lean on the wall, which will reduce the pressure on the ground insulation.

After all these works is not superfluous to make another layer of waterproofing, as the basement - it is very damp room.Thereafter, the finished surface, depending on the purpose of premises, stoning wall panels or tiles.
