Insulation saves energy and reduces GHG emissions, but to be effective, it is especially important to reduce air leaks and heat loss by installing the right insulation in the right place. Attics, walls, floors and foundations all have their own specific requirements, based on their structure and exposure to humidity. No matter where the insulation is being installed, you should always choose the one with the highest R or RSI value.

Our recommendations :

1. Insulation saves energy and reduces GHG emissions, but to be effective, it is especially important to reduce air leaks and heat loss by installing the right insulation in the right place. Attics, walls, floors and foundations all have their own specific requirements, based on their structure and exposure to humidity. No matter where the insulation is being installed, you should always choose the one with the highest R or RSI value.
2. If the concrete slab has to be re-poured, install a layer of rigid insulation panels underneath, as well as a polyethylene membrane.
3. If the concrete slab is not insulated from the outside, installing insulation inside under the floor covering will keep the basement warmer and dryer.
4. Adding a subfloor is especially important if the concrete slab lies directly on a gravel bed. First cover the concrete with a polyethylene membrane before laying down joists and plywood. Choose low-emissions wood products from certified forests.
