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).
  • For AC VCM IF skylights, measurements always taken from inside curb rough opening.
  • We recommend the inside fastening as it allows for a cleaner finish of drywall in the lightwell, with the PVC frame.
  • The PVC Base Frame is used for sizes up to 5’ x 5’. Measurements are always inside curb. Larger skylights require an aluminum outside fastening base frame for strength and rigidity.
  • All skylights are reversible, and should be specified when ordered.

Ac vcm_benefits 1
Larger Sizes Than Glass
  • One of the major benefits of acrylic is its ability to be used in larger skylights than are possible with glass.
  • If you’re designing a dramatic architectural skylight feature above a kitchen, living room or over an indoor pool acrylic is a great option.
  • For the larger sizes we provide an aluminum  interior base frame for additional strength and stability.

Can Be Used on Sloped and Flat Roofs

  • A horizontal installation gives you a unique and dramatic orientation of a view or the sky.

Ac vcm_benefits 5
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.

Ac vcm_benefits 6
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.

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.
