Residential Attics

Create a More Comfortable, Energy-Efficient Home from the Top Down 

Your attic and ceiling assemblies are among the most critical components of your home’s building envelope. When left under-insulated or poorly sealed, these spaces allow heat to escape in winter, permit excess heat gain in summer, and increase the risk of condensation and ice damming. 

BASF’s WALLTITE® closed-cell spray foam insulation provides long-lasting protection, comfort, and efficiency for attics and ceilings of all types—helping you create a more energy-efficient and resilient home from the top down. 

Why Proper Attic and Ceiling Insulation Matters 

  • Energy Efficiency: Heated air naturally rises and can easily escape through gaps, joints, and penetrations in the ceiling. WALLTITE® forms a continuous air barrier that helps retain conditioned air and lowers utility costs. 

  • Ice Damming Prevention: When warm indoor air leaks into the attic, it melts roof snow that later refreezes at the eaves. Properly insulated and air-sealed attics help prevent ice dams, water intrusion, and roof damage. 

  • Moisture and Mold Control: Air leakage can carry humidity into cooler roof spaces, where condensation can lead to mold or rot. WALLTITE® helps regulate moisture and improve indoor air quality. 

  • Comfort and Temperature Stability: A well-insulated attic reduces drafts and temperature swings, keeping indoor spaces more consistent year-round.

WALLTITE® – Closed-Cell Spray Foam Insulation 

For maximum thermal performance and moisture resistance, WALLTITE® closed-cell spray foam provides a dense, continuous insulation layer that serves as both an air and vapour barrier. It offers a high R-value per inch, and proven resistance to condensation and ice damming—ideal for cold Canadian climates. 

Best for: 

  • Unvented or cathedral attics 
  • Roof decks requiring air and vapour control

Key Advantages: 

  • High R-value for compact, space-saving insulation 
  • Integrated air/vapour barrier reduces moisture risks 
  • Durable, closed-cell formulation adds strength and longevity 

Building Better from the Top Down 

With WALLTITE® closed-cell spray foam, homeowners can achieve superior energy performance, enhanced comfort, and long-term building durability. By sealing and insulating the attic properly, WALLTITE® helps improve overall home efficiency, reduce heating and cooling costs, and create a healthier indoor environment. 

Build smarter, build stronger—with WALLTITE® closed-cell spray foam insulation.
