Installation Notes: A mechanically attached system using underlay and Russ strips is useful where the decking is not going to be replaced and the the ballasted system is not chosen. The geo-textile underlay is first laid on the roof followed by reinforced EPDM strips known as Russ Strips form a grid system at 1 metre intervals. These strips are attached to the roof using metal discs and screws screwed directly into the roof decking. The one piece EPDM membrane is then adhered to the grid system using seam adhesive and finished with edge trims leaving a professional long lasting finish.
