Daylighting roof hatches provide the security and convenience of a roof hatch with the added benefits of a skylight. Products feature an impact resistant cover that does not require an additional fall protection screen. The capflashing, fully welded corners, EPDM rubber gasket, fiberglass cover insulation and rigid fiberboard curb insulation ensure weathertightness and energy efficiency. Every roof hatch is designed with the proper number of compression spring operating mechanisms to provide smooth, easy, one-hand operation. Compression spring tubes are made from an anti-corrosive composite material and all other hardware is zinc plated and chromate sealed for corrosion resistance.
Uses and Applications
Access to roof areas is critical to every building maintenance department as HVAC systems and other roof mounted equipment require frequent maintenance and service. BILCO Type GS Roof Hatches provide safe and convenient access to roof areas by means of a fixed interior ladder. Other models are available for ship stair, service stair or equipment access.
Assembly and Installation
Installation of BILCO roof hatches is simply a matter of placing the hatch over the roof opening and securing it to the roof deck through the holes provided in the base flange. The integral capflashing readily accepts roofing felts for built-up roofing applications, and Bilco's patented Bil-Clip® flashing system simplifies installation in single-ply roofing applications.
Materials and Finishes
Roof hatches are available in 11 gauge (2.3 mm) aluminum construction and feature a polycarbonate dome cover design. Double dome covers are also available.
