Frequently Asked Questions
Where should I start insulating?▾
With the attic and air sealing. That is where cost versus gain is best, and it is also what reduces ice dams.
My attic has old granular insulation. Is that risky?▾
If it was installed before the 1990s, have it tested before touching it. Some vermiculite contains asbestos, and disturbing it without precautions is dangerous.
Can more insulation cause problems?▾
Yes, if ventilation is blocked or air sealing neglected. Moisture trapped in a poorly vented attic condenses and damages the structure.
Is financial help available?▾
Energy efficiency programs exist in Quebec and change regularly. Check current conditions with the official bodies before ordering work.
How do I find air leaks?▾
With a blower door test, which locates them precisely. It beats guessing where air gets in.
Insulation in Quebec: what to know
With a heating season stretching past six months, insulation is the first lever on the energy bill and on comfort.
The attic first
It is almost always the best return for the cost. Heat rises, and an under-insulated attic lets a large share of your heating escape. It is also the cause of ice dams at the roof edge. Adding insulation is not enough on its own: ventilation from soffit to ridge must be preserved and air leaks sealed, otherwise moisture gets trapped.
Air sealing
Attic hatch, recessed lights, duct penetrations, window perimeters: that is where heat escapes, even in a well-insulated house. A blower door test locates those leaks precisely.
Vermiculite
In an attic holding beige or golden granular insulation installed before the 1990s, testing is required before any work: some vermiculite contains asbestos.
Ventilation
A tighter house must renew its air. The air exchanger belongs to the project, not to a later step.
