How to properly insulate your house

The energy performance of a house is judged by its insulation. Good insulation will help reduce energy costs. The construction of new houses and housing is now subject to compliance with different standards. It is true that the owner has every interest in insulating his house as much as possible. Insulation must be combined with good ventilation to fight against condensation and humidity in the house.



The heat moves from the hot areas to the cold areas. When a room is heated, the hot air expands and escapes through walls, ceilings, windows ... The insulation will help limit this exchange between the interior and the exterior by attacking to the most sensitive areas such as windows (double glazing for example).

The thermal coefficient determines the quality of an insulation. The lower this is, the better the house is insulated.

Heat emitted from the back of a radiator will escape through the wall it is attached to. To prevent this, put aluminum foil on the back of the radiator.

Insulation solutions


Loose insulation such as glass wool is useful for insulating sensitive areas such as attics and roofs.

Strip insulators are used to insulate flat surfaces and are used for rafters, for example.

Aluminum-based insulation prevents heat loss to the outside.

In order to choose the right insulation, take into account the selling price, the ease of installation, its thermal qualities and the place where it will be installed. For small so-called DIY jobs such as caulking doors or windows, these are simple and useful things to do. Regarding major insulation work, it is advisable to contact a professional.
