Improving insulation
When the roof, foundation and exterior walls of your home are well insulated, they help your home resist better to cold in the winter and excessive heat in the summer. Optimal insulation also makes it easier to maintain a more comfortable indoor temperature and control heating costs. This explains why various renovations targeting the improvement of the home’s insulation are eligible under the Rénoclimat program.
The energy evaluation report that you will receive will indicate the most pertinent type of insulation work to carry out on your home.
