Columbia has decades of experience producing a skylight that can withstand the harsh Canadian climate – the result is a superior energy efficient skylight with a proven history of durability.

Columbia offers an ENERGY STAR® option on every
skylight model and size we manufacture

ENERGY STAR® Canada has one of the most demanding ratings criteria in the world (introduced January 1st, 2020 – Version 5). Columbia is the only Canadian skylight manufacturer to meet the current certification standards.

Columbia’s range of energy efficient fixed and venting skylights

Curb mounted skylights sit on top of a framed wood opening in the roof (the curb). The installation requires an integration into your roofing system - most commonly with metal step flashing and adhesive watertight underlayment (membrane). The advantage of the curb - it is an integral part of the roof and the installer can build to suit the location.

A Self Flashing Skylight is a skylight that comes with a built-in durable PVC vinyl roof curb. Self Flashing skylights are designed for the do-it-yourselfer - you don’t have to build or flash a curb, saving you time and money. Easy to install on any composition shingle or shake roof.

3 variables establish the energy performance of our skylights

Solar Heat Gain Argon
SHGC (Solar Heat Gain)
  • The percentage of solar radiation admitted through a skylight, expressed as a number between 0 and 1. The lower a skylight’s SHGC the less solar heat it transmits.
U Value Argon
U-Value (also know as U-Factor)
  • The rate of heat loss. The lower the number the greater a skylights’ resistance to heat flow.
Visible Transmittance Argon
VT (Visible Transmittance)
  • The amount of visible light transmitted. A high VT is desirable to maximize daylight levels in your home.
The Columbia Skylights listed below have been rated at a 20° slope. Testing is according to the NFRC program requirements.

Energy savings of double & triple glazing
  • Columbia recommends two options of Cardinal high efficiency glass, selected for the extreme demands of the Canadian climate.
  • LoE3 i89 provides close to triple glazed performance in a double glazed unit.
  • Triple Glazed LoE3-366 Temp/Temp/Temp is the choice for most customers in harsh climatic conditions, for those looking for maximum energy efficiency. It is also available with a laminated glass option, Triple Glazed LoE3-366 Temp/Temp/Laminated (the innermost interlayer holds together in case of breakage).

Utilizes two panes of Cardinal’s LoE3 glazing
  • For maximum energy efficiency Columbia’s triple glazed (Temp/Temp/Temp) incorporates two panes of LoE3 glass.
  • LoE3 creates an excellent all climate skylight because it offers superior performance in colder weather (U-Value) and enhanced performance in summer (SHGC).

Aluminum Frame Icon

Robust aluminum frame
  • Our frames are constructed of rigid extruded aluminum for additional strength and durability. Some manufacturers use thinner gauge rolled formed aluminum coil stock.
  • Aluminium, glass and PVC are easily recyclable.

Reduce Exterior Sound Icon

Reduces exterior sound
  • Double and Triple glazing with argon gas filled air spaces reduces exterior noise transmission. If you require the best sound protection, choose triple glazing including a pane of laminated glass.
  • Sound pollution causes stress and anxiety, turn your home into a quiet relaxing sanctuary.
5
Argon Gas Filled Icon
5
Argon gas filled air spaces
  • Argon gas has natural insulating properties and is inserted into the air spaces of the glazing unit to increase energy efficiency. Argon gas is denser than oxygen and reduces heat loss in the winter, heat gain in the summer and sound penetration, dampening the resonance of exterior noise.
  • Invisible to the human eye and non toxic, argon gas does not impact the clarity of the glass, but does reduce your energy use and costs.
6
Pvc Base Frame Icon

White PVC base frame
  • PVC is the most popular material utilized in window and skylight frame construction. It possesses superior thermal conductivity properties.
  • Columbia Skylights include an integrated 4-sided interior gutter to accumulate condensation and drain to the exterior of the skylight.
  • Condensation is caused by difference in temperature from the outside to the inside, combined with airborne moisture from the heating system, kitchen and bathroom, and can stain your interior skylight lightwell.
  • Some imported skylights utilize a flexible EPDM rubber gasket with a soft narrow gutter, typically on just one of the four sides of the frame with a minimal return, which does not capture and direct moisture to the exterior of the skylight. This approach is not suitable for a northern climate.
