Foundation insulation involves installing rigid insulation panels on the interior or exterior of foundation and basement walls to help protect against frost penetration and heat loss. We typically use R-10 rigid insulation, which is designed to perform effectively in below-grade conditions.

By insulating the foundation, frost is prevented from penetrating the surrounding soil and concrete. This helps reduce the risk of frost-related movement and contributes to a more stable foundation. Foundation insulation also improves overall energy efficiency by reducing heat loss through basement walls, allowing your home to retain warmth more effectively.

In Alberta’s climate, foundation insulation plays a critical role in protecting both new and existing homes from temperature extremes. Whether you are building a new home or repairing an existing basement, proper foundation insulation is a smart long-term investment that enhances comfort, efficiency, and durability.

For homes with walkout basement designs, insulating the exposed frost wall is a building code requirement. Proper insulation in these areas helps maintain consistent temperatures and ensures compliance with current regulations.
