TFP-904 Polypropylene Washer

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.

Properties :

• Firmly locks insulation panels
• Creates a thermal break
• Adheres to the base coat insulator through the keys
• Excellent wind-load resistance
• Finger closures keep the base coat from penetrating the cone
• Made of polypropylene selected for its resistance to alkalis in cement as well as dryness from the sun
