Thermal Insulation

The application of insulation from the outside is the most recommended way for the Portuguese climate. Insulation from the inside is also recommended if the previous solution is not possible.

In some cases, the insulation of the air box can also be considered by injecting, for example, polyurethane.

There are several materials on the market that can be used as insulation, such as expanded polystyrene, polyurethane and cork.
