Do I really need to buy SUNDECOR's recommended closure strips and screws?
In order to ensure long-term warranty coverage, it is highly recommended to use SUNDECOR-approved fasteners and accessories. SUNDECOR corrugated products, fasteners and accessories should be thought of as a system meant to provide the best possible installation. Proper use of the complete system (panels, closure strips, fasteners, etc.) greatly reduces the possibility of problems and insures that product warranty will be honored. Please see the installation instructions for the specific product for details.
Why do I have to predrill fastener holes?
Predrilling the holes insures the panels will have room to expand and contract properly with temperature change. Skipping this step can lead to distorted or warped panels. Please be sure to read the installation instructions located on the specific product’s document page.
