ROOF HATCHES - TYPE NB FOR SHIP STAIR ACCESS
DESCRIPTION:
All Bilco roof hatches are ruggedly built for long, dependable service. Covers
feature a box-type design to support a 40 lb/ft2 (195 kg/m2)
live load. The capflashing, fully welded corners, thermoplastic rubber gasketing,
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 NB Roof Hatches provide safe and convenient access to roof
areas by means of an interior ship stair. The large opening permits easier movement
of maintenance personnel, tools and equipment. Other models are available for
ladder, 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 unique Posi-Flash™ flashing system
simplifies installation in single-ply roofing applications.
MATERIALS and FINISHES
Bilco roof hatches are available in either 14 gauge (1.9mm) paint bond G-90
galvanized steel construction or 11 gauge (2.3 mm) aluminum construction.
Bilco steel roof hatches are supplied with an alkyd based red oxide primer
finish from the factory. Aluminum roof hatches are supplied with a mill finish.
