Systems We provide high performance building envelope systems designed to provide superior protection against the elements. These systems include the roof, exterior walls, foundation and fenestration system. They’re designed to prevent air, water, heat light and noise from entering the building, increasing the durability of the building’s structure and improving indoor comfort. No light source is more perfect than the sun for providing light. It’s naturally bright, free and, contrary to a light bulb, never burns out. Harnessing and transferring that perfect light indoors is the foundation of Solatube International, Inc., and it’s what inspired us to create the very first Solatube Daylighting System more than two decades ago. Polyiso can be installed on both commercial and residential structures, on the roof or in the wall. Polyiso is used as a continuous insulation and commands an impressive market share. It’s lightweight, cost-effective, and provides outstanding return on investment with significant energy savings. Extreme weather. Harsh heat. UV rays. Water swelling. Ponding. Take the worry away with our fluid-applied rubber roof restoration systems and equipment coatings. They have excellent permeability and elongation to maximize protection of roofs, recreational vehicles (RVs), industrial equipment and more for years to come. Elemex® offers the architectural industry new design possibilities with code compliant facade systems that are tested on our proprietary Unity® integrated attachment technology. Including other engineered fastening solutions and accessories, the TRUFAST® brand developed a reputation for high-quality products and outstanding customer service.
