Aluminium Sealing Tape for Multiwall Polycarbonate 38 mm x 25 m

Aluminium sealing tape 38 mm × 25 m is a high-quality, self-adhesive tape designed to seal the upper edges of multiwall polycarbonate sheets. It protects the open channels from dust, debris, moisture, and insects while preventing water penetration from the top. This ensures your polycarbonate panels remain clean, transparent, and durable over time.

Important: Use Aluminium Sealing Tape on the top edge of panels, while the bottom edge should have Breathable Tape to allow ventilation and condensation drainage. This combination prevents trapped moisture and extends the sheet’s lifespan.
