Making the right choice in attic insulation can make a big difference in your home’s energy efficiency, year-round comfort, and usability. Spray foam insulation stands out as a top-tier option, and we’ll tell you more about it today. We’ll also tell you how combining it with fibreglass insulation offers a cost-effective and highly efficient hybrid solution.
Here’s why these are two top choices for your attic.
Why Spray Foam Insulation Stands Out
Spray foam insulation is renowned for its high performance, particularly in attic applications:
- Unmatched Thermal Resistance: Spray foam boasts the highest R-value (thermal resistance) per inch of any insulation material. This means it provides superior insulation, keeping your home warmer in the winter and cooler in the summer.
- Usable Attic Space: One significant advantage of spray foam is its application flexibility. It doesn’t compromise the attic’s usability when applied to the top side of the ceiling. You can still walk in the attic and use it for storage, maintaining functionality while enhancing insulation.
- Comprehensive Air Sealing: Spray foam expands to seal every crack and crevice, creating a complete air seal. This seal can stop drafts, improve energy efficiency, and potentially qualify you for air sealing rebates.
A Spray Foam and Fibreglass Insulation Hybrid
For Vancouver Island homeowners hoping to balance performance and cost, a hybrid insulation approach using spray foam and fibreglass could be the way to go:
- Spray Foam as a Base Layer: When you apply spray foam as the first layer, it offers both insulation and a vapour barrier. It provides a robust shield against temperature fluctuations and moisture ingress.
- Adding Blown-In Fibreglass: You can add blown-in fibreglass to the spray foam base. This combination offers a more cost-effective solution with a high thermal performance. The fibreglass adds additional insulation without the need for multiple layers of spray foam, which can help keep costs down.
