Features / Benefits

BILCO Roof Access Hatches feature a thermally broken frame and cover design that minimizes heat transfer between interior and exterior metal surfaces. The result is a product that provides superior energy efficiency and resists harmful condensation.

Tested and approved to BS EN standards for weathertightness, sound rating and security.

Engineered with compression spring operators to provide smooth, easy, one-hand operation, regardless of size. BILCO hatches meet the requirements of Manual Handling Regulations.

Automatic hold-open arm locks the cover in the open position to ensure safe egress. Grip handle allows for easy, one-hand release and closing.

Overlapping cover design, fully welded corners on cover and curb, closed-cell EPDM rubber gasket, and fully insulated cover and curb ensure weathertightness and energy efficiency.

Constructed with corrosion-resistant materials to provide many years of trouble-free, dependable service.

Heavy gauge construction and positive latching mechanism maintain building security.

Curb features the Bil-Clip® Flashing System, an innovative method to quickly and easily secure single-ply roofing material to BILCO roof products.

Available in many sizes and curb configurations to satisfy any access requirement or installation.
