Technical resources for specifying polycarbonate systems — NBS clauses, U-value data, CAD details, lux guidance, and 48-hour spec support.
Specifying polycarbonate correctly takes about fifteen minutes if you have the right information. Most of the confusion — about U-values, yellowing, structural ratings, and installation details — comes from specifying based on a distributor's catalogue rather than a manufacturer's engineering data.
This page puts everything you need in one place. If you can't find what you're looking for, our technical team responds to spec requests within 48 hours.
What lux level does the space require? What orientation is the aperture? What's the thermal budget?
