Purlin Tape 24mm x 20m roll

Polycarbonate is a dynamic material that naturally expands and contracts with shifting outdoor temperatures. Without a buffer, this movement against timber or metal rafters can create irritating creaking, clicking, or “chattering” noises. This Purlin Tape solves the issue by providing a soft, low-friction interface. By applying this tape to the top of your rafters or purlins before laying your EZ GLAZE or multiwall sheets, you effectively dampen vibration and eliminate the friction noise caused by thermal movement.

Beyond noise reduction, the 24mm wide foam strip serves as a vital thermal break. It prevents the roofing sheets from coming into direct contact with dark-coloured or heat-absorbing rafters, which can otherwise lead to localised heat build-up and potential warping or “stress-crazing” of the polycarbonate.

Key Features and Benefits

• Noise Suppression: Eliminates the creaking and clicking sounds associated with the thermal expansion of polycarbonate sheets.

• Single-Sided Adhesive: Features a high-tack adhesive backing for quick and easy application to the tops of rafters or purlins.

• Anti-Friction Surface: Allows the roofing sheets to glide smoothly over the structure as they expand and contract.

• Thermal Protection: Acts as a barrier against heat transfer from the subframe to the glazing material.

• Durable Foam Material: Resists moisture, rot, and UV degradation, ensuring it remains effective for the life of the roof.
