Made of high-durability polypropylene, the TFP-904 washer has been designed to firmly fasten insulation panels to a structure.
Its large 2” diameter (50 mm) and interior cone design greatly increase panel stability. Inserting the screw in the cone allows non-thermal bridging and reduces the risk of fasteners corrosion.
The TFP-904 will work with or without adhesives, and permits the continuation of work immediately after installation with no waiting period.
