Flashing and solid closures should be used at slope changes. For more information on slope change, please read the ONDURA Installation Guide found in the Downloads section under Resources in the main navigation at the top of every page.
Yes. In high wind areas, fasten the TUFTEX panels on every crown of the corrugations.
The best way to compare costs for roofing materials is based on a “roofing square,” which is 100 square feet. Calculate the cost of material to cover 100 square feet, and then compare the costs. ONDURA will cover 100 square feet with 4.5 sheets.
8 ft. panel = 25 fasteners; 10 ft. panel = 30 fasteners; 12 ft. panel = 35 fasteners; 14 ft. panel = 40 fasteners; 16 ft. panel = 45 fasteners NOTE: All fastening holes must be predrilled and must be 1/8 inch larger than the diameter of the fastener.
In roofing applications, fasteners should be at least 1-3/4” long and placed on the raised ridge of the corrugation profile because water will channel into the valleys of the corrugation profile. The raised ridge is also known as the crown.
In a siding or wall application, fasteners should be positioned in the panel valleys, which will be in direct contact with the supports.
All fastening holes must be predrilled. All fastening holes must be 1/8 inch larger than the diameter of the fastener to allow for expansion and contraction of the panels from changes in surface temperature.

ONDURA Premium Series is manufactured in four colors – Red, Brown, Green and Black.
TUFTEX panels should not overhang the support structure on the sides or the top. Panels may overhang the bottom of the support structure by up to 3″. Excessive overhang creates improper support which could lead to damage to the panels from impact, loads or wind uplift.
A minimum slope of 1 inch per foot is recommended for proper water drainage off TUFTEX panels. A slope of 2 or 3 inches per foot will provide better drainage.
TUFTEX PolyCarb™ panels are made with a tough polycarbonate thermoplastic polymer. These panels can withstand surface temperatures up to 270° F and down to -40° F. The support structure for the panels must be light colored and well ventilated to prevent damage to the panels from excess heat buildup between the support structures and the panels.
Install TUFTEX vinyl panels (SeaCoaster™) over a maximum of 24-inch span on center cross bracing. TUFTEX PolyCarb™ panels can span 36-inch on center cross bracing. SeaCoaster and PolyCarb panels all require 24-inch spacing on rafters. Be sure to check local building code requirements before starting any project.
