36" x 30" Skylight Ladder Access Roof Hatch - Aluminum - Bilco

GS-50 36" x 30" Skylight Ladder Access Roof Hatch – Aluminum – Bilco 

The Bilco GS-50 is a multi-purpose roof hatch that allows service staff to quickly access the roof to check and maintain the HVAC system, solar panels, and other units installed on the top. At the same time, it also provides natural light to the structure's interior, which significantly helps reduces the energy consumption of the building.  

Why Install GS-50? 

Material: The GS-50's polycarbonate dome is a durable and practical material that helps reduce artificial light by letting the natural light pass through the access roof panel, which can improve the ambiance of the building's interior and, at the same time, reduce the structure's energy consumption. 

The 11 gauge (2.3 mm) lightweight aluminum and its durability also help make the skylight consistently efficient all year round. It is corrosion-resistant and can withstand different weather conditions. Utilizing polycarbonate and aluminum materials makes the GS-50 the best skylight ladder access roof hatch for your building.  

Weathertight: Bilco designs GS-50 to prevent water leakage and keep harmful chemicals and elements from infiltrating the building, which may cause extreme damage to the structure in the long run. The weather tightness of the equipment roof hatch also helps regulate the building's  

temperature, minimizing air leakage and temperature fluctuations. 

Accessibility: The GS-50's uncomplicated and user-friendly design allows authorized building personnel to quickly and safely access the roof. The access roof door's compression spring operators and automatic hold-open arm feature also help prevent the cover from accidentally opening or closing, which may cause injuries to people using it.
