The Duro-Last Insulation Plate is a distribution plate designed to hold insulation and underlayment boards under the Duro-Last roofing system. The Duro-Last Insulation Plate includes a recessed diameter hole in the center, keeping the head of the fastener from coming into contact with the Duro-Last roofing membrane. In addition, there are tabs pressing against the fastener head to prevent the fastener from backing out. To maintain necessary strength and position, the Duro-Last Insulation Plate is manufactured with a thick center that embeds into the insulation and a thin flexible exterior to help reduce facer tear. The Duro-Last Insulation Plate is a long-lasting, durable plate that is available only from Duro-Last, Inc.
