Attic Insulation and Ceilings

Cathedral ceiling and attic insulation is essential to maintain a comfortable temperature and optimize your home's energy efficiency. Spray foam offers an effective solution for these hard-to-insulate spaces.

Cathedral ceilings, triangle-shaped under the roof, and attics require effective insulation to avoid significant heat loss. Up to 25% of a home's heat can escape through the roof if insulation is inadequate.

Why insulate your attic and ceilings?

Heating savings

Reduce roof heat loss which can reach 25%.

Summer comfort

Keep your home cool by blocking sun heat on the roof.

Winter protection

Avoid ice dams and condensation problems in the attic.

Livable space

Transform your attic into comfortable living space year-round.

Air tightness

Return on investment

One of the renovations with the best return in energy savings.

Types of ceilings we insulate

Cathedral Ceilings

Cathedral ceilings, with their sloped shape following the roof pitch, are particularly difficult to insulate with traditional methods. Spray foam is applied directly between rafters to create a continuous thermal barrier.

This method eliminates thermal bridges and offers superior insulation in reduced space, essential when ceiling height is limited.

  • Between-rafter insulation
  • High R-value per inch
  • Thermal bridge elimination
  • Tight spaces

Lofts and Attics

Attic insulation can be done either on the attic floor (if the space isn't used), or under the roof (for finished attics). Spray foam is ideal for sealing the many penetrations and junctions present in these spaces.

Good attic insulation also prevents condensation and ice dam problems in winter, thus protecting your roof structure.

  • Attic floor
