Prefabricated Curbs - Skylights

Prefabricated Curbs

Economical and Convenient Alternative to Site Built Curbs

Wasco’s prefabricated curb mounted skylights are fully welded and assembled to reduce installation time and cost, with no chance of missing parts and no field assembly. Available in structural uninsulated or nonstructural insulated models.

Our structural curbs eliminate the need for costly structural reinforcement by eliminating the need for structural steel sub frames when mounted to the steel joists of the building prior to deck installation.

Curbs come standard with an impact tested security screen. The screens are fabricated in a 6″ x 6″ welded grid pattern using 3/16″ cold-rolled galvanized steel rod.
