Most people think spray foam is only about R-value.

The truth is, one of its biggest benefits is creating an air seal that helps keep conditioned air in and unwanted drafts out.

Hybrid Roof Insulation System 🏠

Every roof is different, and this one had limited cavity depth. Our solution was a high-performance hybrid system that maximized insulation while remaining cost-effective.

✔️ 3” of closed-cell spray foam to create a continuous vapour barrier and add R-value.
✔️ An additional 5.5” of closed-cell spray foam to complete the hot roof assembly.
✔️ 8” of blown-in cellulose where cavity depth allowed to further increase the overall R-value.

Up to 30% of heat loss comes from air leakage.

This is one of the areas we address👇

Closed-cell spray foam is being applied to the roof deck, creating an unvented roof system.

• Stops air leakage
• Insulates at the same time
• Improves overall efficiency

Traditional insulation slows heat transfer.
Spray foam does both — it seals and insulates.
