Insulation Plates, also called Stress Plates, are designed for use with #12 diameter Roof Deck Screws and 1/4" dia. Roof Spike anchors. Stress plates are used when attaching insulation and single ply materials to distribute load and prevent the material being fastened from pulling over the head of the fastener. In addition to the stress plates, a EPDM bonded stainless steel backed sealing washer is also available for use with flashing and termination systems.

Powers Insulation Plates Insulation plates are used when mechanically attaching rigid form insulation to roof decks. They are manufactured in 3" diameter for use with No.12 Deck Screws and 1/4" Spike anchors. The design of the insulation plate allows it to flex during installation if a fastener is overdriven preventing fracturing of the insulation board and facer. Sharp edges which could protrude above the insulation surface are eliminated by the round design. For corrosion resistance, a Galvalume coating is applied to the carbon steel plates. This coating, comprised primarily of aluminum and zinc, provides a degree of corrosion resistance which allows the material to meet the corrosion resistance required by FM Global Standard 4470.
