What is the proper cross-brace and rafter support for TUFTEX?

Install TUFTEX vinyl panels (SeaCoaster™ & UltraVinyl™) over a maximum of 24-inch span on center cross bracing. TUFTEX PolyCarb™ panels can span 36-inch on center cross bracing. SeaCoaster, UltraVinyl, and PolyCarb panels all require 24-inch spacing on rafters. Be sure to check local building code requirements before starting any project.
