This not only improves energy efficiency but also boosts the overall durability of your home. When you find them, seal them up using suitable materials like spray foam insulation, caulk, or weatherstripping. It’s wise to inspect your walls and framing for these gaps. Gaps in Framing & Sheathing: Any gaps in the framing and sheathing of your home can cause issues like energy inefficiency, moisture problems, and even structural concerns.Consider using airtight and IC-rated fixtures to maintain a proper seal and prevent heat loss. Be cautious with insulation around these fixtures if they’re not rated for direct insulation contact (non-IC rated), it can be a fire hazard. To prevent conditioned air from escaping your home and to stop outside air from entering your home, you need to seal them correctly. Recessed Light Fixtures: You might know these as can lights or downlights.

This not only helps with insulation but also helps to seal around any gaps. To do this, you can use gaskets or foam inserts behind the outlet cover plates. It’s essential to make sure they’re sealed properly to keep out drafts, moisture, and pests. Outlet Boxes on Exterior Walls: These outlet boxes are the ones you see on the outer walls of your home, often used for electrical outlets or switches.In any home, hundreds or thousands of tiny little gaps in the building envelope add up to a LOT of air leakage and infiltration. Why Sealing Air Leaks in Your Home is so Important On our path to net zero, we’re taking more time and care to get the details right.Įven after the insulation and vapour barrier is done, we’ve still got one major step that’s going to dramatically improve the performance of the house - we’re going to be partnering with Aeroseal to do a whole-home air sealing application.įor someone who’s spent the better part of 4 years manually running around houses with a caulking gun trying to seal up leaky areas, I couldn’t be more excited. These are all things we won’t see when the house is done but is critical for how the house feels and performs. It’s been a busy time of stuffing wall cavities with batts and taping up our air and vapour barrier. The past few weeks at the house have been all about insulation and air sealing.
