The PolyX PVC Sheet End Closure is an essential component for DIYers and professional roofers working with 16mm polycarbonate roofing systems. Its primary benefit is providing a clean, weather-resistant finish that prevents dust and debris from entering the sheet flutes while directing rainwater effectively into the gutter. While it offers superior protection, it must be installed after the proper application of anti-dust breather tape to prevent internal condensation and algae buildup within the roofing panels.

No, this specific profile is engineered exclusively for 16mm polycarbonate roofing sheets.
Generally, the profile is designed to be a friction fit. However, you can use a small amount of neutral-cure silicone if you want extra security against high winds.
It is finished in white PVC. While it can be painted, the surface may require a specific plastic primer, and paint may flake over time due to thermal expansion.
The tape allows the sheet to breathe while preventing dust, insects, and mould from entering the internal flutes of the polycarbonate.
It is designed to manage water flow and provide a physical barrier against debris, but it is not a pressurized waterproof seal.
Ensure that the anti-dust breather tape is not too thick; if it is, the profile may not seat fully. If it remains loose, apply a small amount of clear silicone adhesive to the inside of the profile before fitting.
Check that the sheet is positioned correctly so the drip lip extends far enough over the guttering edge. Adjust the positioning of the polycarbonate sheet if necessary.
To install, ensure the 16mm polycarbonate sheet edge is clean and dry. You must first apply anti-dust breather tape to the open end of the sheet to ensure proper ventilation; omitting this step can lead to trapped moisture. Once the tape is applied, push the PolyX profile firmly onto the end of the sheet until it is flush. No heavy adhesives are required, though a small bead of neutral-cure silicone can be used if you require a semi-permanent bond. For care, simply wipe down the profile with a soft cloth and mild soapy water during your seasonal gutter cleaning to maintain the finish.
