Bonus Rooms
Comfort Above the Garage—All Year Long
Many homes feature a finished room above the garage, often called a bonus room. While it adds valuable living space, this area can be difficult to keep comfortable. In summer, it can become excessively warm, and in winter, uncomfortably cold.
When the temperature in your bonus room mirrors the weather outside, it’s a sign of inadequate insulation and air sealing. BASF’s spray foam solutions—WALLTITE® closed-cell and ENERTITE® open-cell—provide high-performance insulation systems that help create consistent comfort and energy efficiency all year round.
High-Performance Insulation for Bonus Rooms
The key to improving comfort in rooms above garages is controlling air movement and temperature transfer between the garage ceiling and the floor above. BASF spray foam insulation expands on contact, filling every gap and joint to create a seamless air barrier that prevents drafts, condensation, and energy loss.

WALLTITE® Closed-Cell Spray Foam
WALLTITE® is a high-performance closed-cell spray polyurethane foam that acts as an insulation, air barrier, and vapour barrier in one. Applied to the underside of the garage ceiling or within wall cavities, it creates a durable, continuous layer that stabilizes the room’s temperature while protecting against moisture and condensation.
Ideal for:
-
Garage ceilings beneath bonus rooms, areas with temperature or moisture imbalance, and projects requiring vapour barrier performance.
Benefits of WALLTITE®:
- Superior Thermal Performance: High R-value per inch ensures maximum efficiency with minimal thickness.
- Air & Vapour Barrier Protection: Reduces drafts and moisture infiltration to improve indoor air quality.
- Long-Term Energy Savings: Helps lower heating and cooling costs throughout the home.
- Durable & Long-Lasting: Closed-cell structure resists sagging, settling, and deterioration over time.
ENERTITE® Open-Cell Spray Foam
ENERTITE® is an economical open-cell spray polyurethane foam designed for interior wall and ceiling applications. It provides excellent air sealing, thermal insulation, and sound attenuation—ideal for enhancing comfort and reducing noise in living spaces above garages.
Ideal for:
-
Bonus room walls and ceilings, interior partitions, and applications where sound control and flexibility are desired.
Benefits of ENERTITE®:
- Comfort & Efficiency: Reduces air leakage and maintains consistent indoor temperatures.
- Acoustic Control: Absorbs sound for a quieter, more peaceful living environment.
- Lightweight & Expansive: Fills irregular cavities completely for seamless coverage.
- Cost-Effective Insulation: Provides comfort and energy efficiency at an accessible price point.
