Roofs, Skylights, & Canopies

Skylights and Canopies
 
 


The design flexibility of Pilkington Planar and the elimination of metal framing, which can cause maintenance problems over time, makes Pilkington Planar the perfect choice for horizontal and overhead glazing. Pilkington Planar overhead glazing has undergone extensive seismic, bomb blast, impact, water and wind load testing.
 
 


We exclusively use cast-in-place (CIP) liquid resin in lieu of PVB to laminate our glass. The CIP resin used to laminate our glass has successfully undergone 2,000 hour accelerated life cycle testing. The use of CIP allows us to expose the edges of our glass to the weather and silicone sealants.
 
 


Backup structures can be supplied as a completely engineered sole source package for guaranteed performance of the complete skylight or canopy.
 
 


TECHNICAL CONSIDERATIONS
The backup structure is required to carry snow loads and resist negative wind pressures through the fixing locations. Large spans are possible if underlyiing purlins are reinforced with cable tension rod rigging (see Orlando Airport). Pilkington Planar requires a minimum of 3 degrees of slope to eliminate ponding of water in the center of the glass.
