Stop Air Leaks, Save More: The Overlooked Role of Air Sealing in Insulation Projects

Martha Laverde • July 21, 2025

Insulation alone isn’t enough. Here's why air sealing is essential for lasting energy efficiency.

Most people think adding insulation is the only way to improve energy efficiency. But without proper air sealing, even the highest R-value insulation can fall short.  In this post, we’ll explore why spray foam insulation is the ideal air-sealing solution, especially for Edmonton’s unpredictable weather.


The Hidden Problem: Air Leaks

Cracks, gaps, and poorly sealed framing let heated or cooled air escape, making your HVAC system work overtime. According to Natural Resources Canada, up to 30% of a home’s energy loss can come from air leakage.


Why Spray Foam Is a Game-Changer

Unlike traditional insulation, spray foam expands to fill every gap, acting as both insulation and a vapor/air barrier.
This provides a continuous envelope of protection, helping reduce:

  • Heat loss
  • Moisture buildup
  • Drafts and cold spots


Edmonton-Specific Benefits

With cold snaps, chinooks, and dry winters, Alberta homes demand a higher level of building envelope performance. Spray foam's airtight seal combats ice dams, mold growth, and shifting R-values better than any other solution.
