Can foam be insulated by putting foam on the balcony on the top floor of a house?

Yes, foam is a porous plastic product, and the micropores can store a large amount of air, and the heat conductivity is very poor, so the thermal insulation effect is better.

Hello! Foam boards can be insulated, but they are lighter and should be reinforced.

and counterweights.

It can be insulated, but the choice of thermal insulation foam board, it is best to have a higher density, at least above the density of 16 kilograms of cubic meters, light, thermal insulation effect, strength, are not satisfactory.

In the north, it should be 5--10 cm thick, and in the south it should not be less than 5 cm.

It is best to use extruded plastic board, which can achieve a density of more than 30 kilograms of cubic meters. And the price is comparable to foam board, with a density of more than 20 kg cubic meters, which is cheaper than foam board. Foam board can be insulated.

1.Use flame-retardant foam board as much as possible to prevent fire.

2.Clean the roof before laying.

3.It is necessary to make the foam board and the roof structure layer bonded well.

4.The top layer of the foam board should have a waterproof layer. If it is soaked in water, it will reduce the thermal insulation effect.
