The panel fastening systems is uniquely designed to handle the potentially damaging effects of thermal movement. The clips have a moveable feature allowing the panel to expand and contract with temperature changes. The concealed clip system means fewer through roof fasteners, reducing the chances of leaks. It is designed as a water barrier. The raised seam assists drainage.
Organic sealants are factory applied inside the seams.
Automatic field seaming machines produce weathertight connections between metal roof panels. Systems accommodate up to 12 inches of heat and cold and minimizing condensation under roof panels. Concealed sliding clips handle thermal shock for permitting movement without damage. Roofs qualify for a class 90-wind uplift rating of new and retrofit construction, the highest rating given by Underwriters Laboratories. Standing seam metal roofs pay for themselves from the day they are installed.
