How to properly insulate your home to consume less energy?

Insulating your home is the best way to limit heat loss. If heat loss is too great, it will make your home uncomfortable and difficult to heat, and will also increase your energy bills. For optimal insulation, it is often mandatory to use the services of a professional.

Identifying the main heat leaks

It is difficult to properly insulate your home if you don’t know where the heat loss comes from, because heat loss can be varied. A heat survey, carried out by a professional, will allow you to pinpoint the areas of the house where heat is escaping and where the insulation should therefore be the most important. In the majority of cases, it is through the floor, walls and attic space that it leaks most easily, at rates of 10, 20 and 30% respectively of the total heat produced by your heating appliances. With an average of 30% of energy lost, the attic is the main cause of poor insulation in a house and must therefore be treated as a priority.

Call on a professional

For good quality insulation, it is necessary to entrust your renovation work to a professional, whose experience and know-how are indispensable. A professional, indeed, will know how to best adapt your insulation to your needs as well as to the characteristics of your home. In particular, he will know whether it is preferable to opt for interior or exterior insulation, as each has its advantages and disadvantages in terms of efficiency and cost. Of the various insulating materials such as mineral wool, cellulose wadding, phenolic foam or polystyrene, the professional will choose the most suitable, as well as its shape: foam rolls, rigid panels, granules to be poured or foam to be sprayed. Mastery is necessary to successively lay mesh, vapour barrier, insulating layer and finishing coat while guaranteeing the best durability.

Favouring roof insulation

As we have said, attic insulation is the most important part of the house and must therefore be carried out with care. Neglected, it would have little effect on your energy consumption and would even make the insulation work undertaken on the other parts of the house, walls or windows, seem insignificant. It is therefore essential that the roof is properly protected, especially at the thermal bridges formed by the roof corners, through which heat leaks more intensely. Insulating the attic of the house correctly will have an immediate effect on your heating bills, which can be reduced by almost a third, but also on the overall comfort of your home, which is quicker to heat and less humid. The energy class of your home will be permanently improved, and your home will therefore increase in value over the long term.
