Achieve energy savings with the VELUX CM curb mount commercial skylight
The VELUX CM curb mount commercial skylight provides high levels of visible light transmittance which has been shown to significantly reduce these energy costs through the benefits of daylighting. The payback from installing the CM curb mount commercial skylight in commercial and industrial applications is typically less than three years.

Quality construction
VELUX manufacturers the highest quality commercial skylights in the industry. We extrude only high quality acrylic that does not yellow over time like competitor's skylights. The CM curb mount commercial skylight also has an advanced weep system which minimizes condensation, and a full thermal break to maximize energy efficiency.

Commercial fall protection

The VELUX CAP and CM commercial acrylic or polycarbonate dome glazed skylights of certain size and construction have been tested by an independent third party to withstand the applied 200 lb load listed in OSHA 1910.23(e)(8)  The VELUX skylight type and size limits are CAP and CM units equal to or less than 6’ x 6’ or 4’ x 8’.  

The VELUX construction limits are that these skylights need to be made with the following glazing variants:  04D (clear over clear acrylic), 04F (white over clear acrylic), 04I (clear polycarbonate over clear acrylic), and 04V (clear polycarbonate over white acrylic).   Any other glazing thickness, glazing variants, or sizes greater than those listed above for CAP and CM unit skylights are not covered by VELUX "OSHA Fall Protection Test Reports"

Fall protection Screens
Screens provide OSHA fall protection for flat roof commercial skylights.  The screen system provides fall protection without damaging your skylight.  A special retaining bar locks to the domed skylight unit at the corners thus keeping the screen from damaging the integrity of the skylight.

Skylights come in a wide range of glazing options to meet the aesthetics and the budgetary constraints of a project.  Not all VELUX skylights are designed and tested to withstand OSHA fall protection loads.  To reduce the risk of someone falling through a skylight, it is recommended that screens and safety railings always be used to ensure long term compliance with OSHA’s fall protections regulations.
