Columbia offers two curb mount fastening systems

  • Columbia manufactures outside and inside fastening skylights (the method by which the skylight is fixed to the curb).
  • We recommend the outside fastening as it allows for a cleaner application of drywall in the lightwell, with the PVC frame of the skylight hardly visible.
  • For GL VCM OF skylights. Measurements are always taken from the outside finished (flashed) curb dimensions.
  • All skylights are reversible, and should be specified when ordered.

    Durable extruded exterior aluminum frame with baked enamel paint finish. 7 standard colours and unlimited custom colour matching – bring in a paint chip to your dealer and we will match it.
  2. Base Frame

  • Columbia manufactures outside and inside fastening skylights (the method by which the skylight is fixed to the curb).
  • For GL VCM IF skylights, measurements always taken from inside curb rough opening.
  • Inside fastening is a previous Columbia design, and if you are replacing skylights with this type of fastening flange, it may be preferable to replace them with the same, to avoid interior finishing work.
  • All skylights are reversible, and should be specified when ordered.

The Benefit of Natural Light
  • Living in the north we all need more natural daylight in our homes, particularly during the winter months when days are shorter, there are fewer hours of sunlight, and the sun is at a lower angle than during the summer.
  • Natural light has been proven to increase happiness and productivity.
  • Increasing the amount of natural light in your home offsets the impact of Seasonal Affective Disorder, which affects many people in the winter when they do not receive enough sunlight.
  • Natural light has been shown to lower the risk of nearsightedness in children and young adults by helping the eye produce dopamine, which aids in healthy eye development.

Efficient ENERGY STAR® Low E Double or Triple Glazing With Argon Gas
  • For maximum energy efficiency select from Columbia’s wide range of ENERGY STAR® LoE3 366 with advanced triple LoE coated glazing options – double and triple glazed. All options are available with laminated inner lite.
  • The space between the glass panes is filled with argon gas, a natural, non toxic, high performance insulator.
  • Because argon is denser than air it is superior at insulating your home than a conventional double pane skylight. It reduces cold or hot temperatures from transmitting through the glazing unit.

Economical and Adds Value
  • Columbia curb mounted skylights are manufactured in Canada using North American materials, making them more economical compared to foreign products.
  • Skylights add to the value of your home investment as it is highly desirable to bring natural light and fresh air into your home.
  • Today’s ENERGY STAR® certified skylights save you money compared to older models of skylights with inferior design, and provide more comfort.

Frame Colours To Match Every Roof
  • Seven standard frame colours are available on all models, fixed and venting, including custom sizes.
  • Architects design natural light into the interior of the home; however, they want the skylight to blend with your roof covering to highlight their roof design. Contrasting the skylight frame with your roof colour can be unattractive and an eyesore.
  • Bring in a paint chip to your dealer, and we will match it. Ideal for large colour selection of steel and other roofing materials.

Curb Mounted Skylights, the Professional’s Choice
  • The preferred skylight mount for any type of roof, primarily for use on tile, shingle or wood shakes. Recommended by roofing professionals as the optimum choice for a long lasting, trouble free installation.
  • Curb Mount is the top installation choice across North America. It allows the roofer to adapt to the specific need of the situation, ensuring the perfect watertight bond between the roof, the curb, and the skylight.
  • Installed on all types of site built curbs, whether pre-existing or new. For additional weather tightness, ensure you use roofing membrane in addition to recommended flashing on the curb.

Columbia is the only skylight manufacturer offering triple glazing on all skylight models, fixed & venting, standard and custom sizes.

The benefits of Columbia’s laminated glass

Offering the extra strength and protection of laminated glass on all Columbia glazing options. Consider our most popular choices – double glazed LoE3 366 Tempered/Laminated and triple glazed LoE3 366 Tempered/Tempered/Laminated.
Sound reduction airplane
Superior Sound Reduction

Reduces the effects of sound by up to 30% compared to standard double pane glass, and up to 50% less than a acrylic dome skylight.

Bring natural light in without additional noise such as traffic or planes.

Hammer resistant security glass
Additional Security

Laminated glass is far harder to break and penetrate than traditional glass.

So, if you are concerned about security it is worth considering. The innermost interlayer holds the glass together in case of breakage.

Uv protected glass
Best in class UV Protection

Laminated glass lets the light in but protects your home from UV rays. The ideal choice to prevent fading of your floors, furniture and artwork.

triple-glazing
We offer triple glazing on all models

Why Columbia

Canadian made skylights, designed for our harsh climate

Columbia skylights are specifically designed for life in our Canadian climate. Whether subjected to snow, ice, wind, hail, or intense heat, our products are engineered to outperform these demanding conditions.

Many imported skylights are designed for a more temperate climate and lack the performance and durability. Columbia has spent many decades manufacturing premium quality skylights that have stood up to the test of time in our Canadian climate.

Every aspect of the skylight has been studied, engineered, and tested.

Columbia utilizes the best materials available, including the latest glass technology.

Energy efficiency is a concern for Canadian homeowners because of our extreme climate. Columbia is the only Canadian manufacturer to offer Triple Glazing on all our skylight models, fixed and venting. We offer more ENERGY STAR® glass options than any other manufacturer.
