CANADA’S Choice for
Canadian Made Skylights White

Columbia has engineered its skylights to withstand the demands of the extreme Canadian climate and meet the current ENERGY STAR Canada standards.

Aluminum Exterior Frame
Durable extruded aluminum frame with baked enamel paint finish.
Double or Triple Glazing
Choose from Cardinal Glass Industries Double and Triple glazing options to meet ENERGY STAR requirements.
PVC frame
Highly efficient long lasting PVC frame, thermally broken. It doesn’t conduct cold from the exterior to your home’s interior.
Adhesive ‘wet’ seal
Columbia recommends sealing your skylight to the curb with long lasting flexible silicone caulking or glazing tape - this ensures no air leakage, water infiltration or heat loss. Provides additional protection over rubber gaskets that do not adhere to uneven curb surfaces.
Aluminum flashing is the primary protection against water penetration. Can be supplied by Columbia or your installer. Integrates the curb to your roofing system and protects against moisture, snow, ice and wind. Designed for Columbia’s Fixed and Venting Curb Mount Skylights. Features pre-cut aluminum steps and pre-formed head and sill flashings. Ask your contractor about an insulated curb.
Roofing Underlayment
Rugged puncture resistant self-adhesive membrane eliminates air and water penetration.
Curb mount
Lifts the skylight off the roof deck to minimize snow and ice build up. The curb is structurally part of the roof, so it creates a secure water tight bond for the skylight to sit on.

Energy Efficient Skylight Installation

For maximum energy efficiency, professional installation and advice is critical

  • Much of the energy loss associated with a skylight comes from choosing the wrong skylight for the application or poor installation (causing air leakage).
  • The insulation of a skylight needs to integrate into a properly designed and installed building envelope system.
  • Ensure the building envelope meets current ENERGY STAR and building code standards for all material incorporated in your home.
