Create a Roof Deck up to 15 Inches off of TPO

Grad Concept USA has announced the North American launch of the Grad Rooftop Decking System.

The thermoplastic polyolefin (TPO)-friendly system makes installation simpler, easier, and up to 50 percent faster than conventional decking, while requiring fewer people to do the job. Utilizing screw-adjustable pedestals, the waterproof system raises the deck floor off the TPO as high as 15 inches. The subdeck remains easily accessible since boards can be individually removed no matter where they are located.

The Grad system comes with clips that are already pre-fastened into place and cannot be moved. When specially profiled boards are snapped onto the clips, they are always straight and gaps are even, therefore eliminating the need for control checks. Boards can be removed, replaced, and updated at any time. The modular system is easy to move around, adjust, and remove, if necessary, which is not typically possible with traditional decking. 

Grad’s attachment components are virtually maintenance-free, offering maximum resistance to rot. The polypropylene pedestals, which meet ASTM D1929 and D635 standards, provide a stable, durable, and stiff infrastructure for attachment, while the polyoxymethylene fasteners (which are not exposed to direct UV light) offer strength and flexibility.

The Grad Rooftop Decking System, which can also be used for poolside decking, is compatible with many different Grad-approved decking brands, including a wide range of natural wood and thermally modified wood species, bamboo, and aluminum options.
