How to Apply Aluminium Tape

1. Choose the Correct Tape – Ensure the tape matches your sheet thickness.
2. Cut to Size – The tape should be 50mm wider than the sheet width (allowing a 25mm overhang on each side).
3. Prepare the Sheet – Peel back the protective film on both sides and clean the sheet’s edge to remove dirt and moisture.
4. Apply the Tape –Stick the tape to the top surface, aligning it evenly along the sheet width.
5. Fold it over the open flutes, pressing down firmly to create a secure seal.
6. Ensure an equal overhang on both sides.
7. Seal the Ends – Fold and stick down the 25mm overhang at each end to create a neat, secure seal.
8. Attach End Closures – Always fit a sheet end closure over the tape to prevent water ingress and enhance durability.

Following these steps ensures your sheets remain clean, ventilated, and long-lasting.

Which Tape Do I Need If I’m Cutting My Sheets?
If you are cutting down your polycarbonate sheets, you will generally only need perforated anti-dust tape to reseal the bottom edge. This allows moisture and condensation to escape, maintaining sheet clarity. However, if you cut both ends, you will need both solid aluminium tape for the top and perforated tape for the bottom.

Do the Top and Bottom of the Sheets Use the Same Tape?
No. The top edge of multiwall polycarbonate sheets is sealed with a solid aluminium tape to prevent debris and moisture ingress. The bottom edge requires perforated anti-dust tape, which allows ventilation and helps condensation escape.
