Kalwall & Fiberglass Skylights

Kalwall Skylights

Kalwall skylights are made with FRP, or fiber-reinforced polymers, commonly known as fiberglass. All fiberglass constructed skylights require maintenance. Cleaning the skylights periodically is helpful in removing pollution and light-blocking dirt from the exterior surface.

Fiberglass skylights have an exterior gelcoat that helps reduce damage from UV rays, but this wears away over time. It depends upon the manufacturer and even when it was manufactured to determine how often the fiberglass gelcoat needs replaced or re-coated. This is critical to fiberglass skylight care, as it prevents fiberbloom, which leads to water infiltration, discoloration, bacterial infection and unpleasant odors.

Fiberglass skylights are commonly used on commercial buildings because they are much more cost effective than glass. They also provide diffused light, which reduces heat gain, glare and other discomforts usually caused by glass glazing.

Polycarbonate is another option to consider. Like fiberglass, it is much more cost effective than glass glazing, and provides improved energy efficiency over both glass and fiberglass glazing. It also has reduced maintenance costs, and doesn’t need UV gel coats.
