How to insulate the ceiling with foam
Where to begin
As everyone knows, the temperature in the room is an important factor affecting the pleasantness of spending time in the house, therefore, special attention should be paid to thermal insulation. The greatest heat loss is carried out through the ceiling, therefore, when repairing the ceiling, almost every home owner makes its insulation.
How ceilings are insulated
When carrying out finishing work with the help of polystyrene, one should remember its advantages, but do not forget about the disadvantages. In general terms, we have already indicated the most significant pros and cons, however, it seems to us that this issue should be studied more closely.
Advantages of foam:
Insulation using this material does not need mandatory vapor and waterproofing, since this insulation itself has zero hygroscopicity and vapor permeability.
A distinctive feature of foam is its ability not to cake over time, which cannot be said about mineral wool. It is able to fully preserve its thermal insulation characteristics for the entire operational period.
Polyfoam has a unique structure, due to which, with an equal thickness of layers of insulation materials, it demonstrates the best qualities, in contrast to mineral wool.
Low thermal conductivity for a long time. This guarantees reliable heat retention inside the building.
As you can see, there are many advantages. But, when performing interior design at home, you should also know the disadvantages:
This material costs significantly more than mineral wool.
It is slightly more difficult to equate polystyrene in the parameters of the made crate.
As we already recalled above, foam plastic does not provide complete fire safety, since it is highly flammable. An unpleasant odor is emitted during combustion. Although, this can be attributed to the pluses – by the smell it will immediately become clear that something is wrong in the house.
Having weighed all the advantages and disadvantages, one conclusion suggests itself: the scale with pluses outweighed the scale with minuses. So, do not be afraid to make renovation using this material – if you do not care about the price of insulation, it will be an ideal option.
Foam insulation methods
There are several methods of foam insulation. Let’s take a look at one of them.
Most often, insulation is used in private houses with a cool attic, where the ceiling is connected from below to wood beams with OSB or plywood. Insulation stages in such a situation:
cleaning surfaces from debris and dust;
installation of foam plates from above into the area between the beams, the gap should be minimal; thorough foaming of the seams between the beams and the insulation;
covering the ceiling with OSB or beams, if the attic will be used.
In this example, we have shown the general principle of foam insulation. However, in different situations and approaches are different, so it is still better to consult with specialists .
