Breathable Tape for Multiwall Polycarbonate 25 mm × 5 m

Breathable Tape for multiwall polycarbonate is an essential accessory used during the installation of twinwall and cellular polycarbonate sheets. This perforated vented tape protects sheet channels from dust, insects, moisture, and debris, while allowing condensation and water vapor to evaporate naturally. Correct use of breathable tape helps maintain panel transparency, durability, and long service life, especially in greenhouses, roofing, pergolas, and outdoor constructions.

Key Difference from Aluminium Sealing Tape

• Aluminium Sealing Tape is applied to the top edge to prevent water, dust, and insect ingress, fully sealing the channels.
• Breathable Tape is applied to the bottom edge to allow ventilation and condensation drainage, without blocking airflow.
• Using both tapes together ensures clean, protected channels and longer service life for multiwall polycarbonate panels.

Reliable Protection for Polycarbonate Sheet Edges

Multiwall polycarbonate sheets have internal channels that require proper ventilation and sealing.
Breathable perforated tape creates a ventilation layer that lets moisture escape, while preventing dust, algae, and insect contamination.

Benefits of Using Breathable Tape:

• Prevents condensation inside sheet channels
• Blocks dust, algae, and insect ingress
• Protects edges from environmental damage
• Maintains optical clarity of panels
• Extends service life of polycarbonate roofing and greenhouse systems

Where and How to Use Breathable Tape

Breathable Tape is installed on the bottom edges of multiwall sheets to:

• Allow proper airflow and ventilation
• Facilitate condensation drainage
• Ensure channel protection without blocking moisture escape

Typical applications include:

• Greenhouse polycarbonate panels
• Roofing and canopy systems
• Pergolas and terrace covers
• Garden shelters and outdoor structures

Installation Instructions

1. Thoroughly clean and dry the bottom edge of the polycarbonate sheet.
2. Remove the protective film from the tape adhesive.
3. Apply Breathable Tape along the bottom edge, pressing firmly.
4. Smooth out any bubbles or wrinkles to ensure proper ventilation.
5. Seal the top edge with Aluminium Sealing Tape to prevent water and dust ingress.

Additional Tips:

• Always combine tapes: Aluminium Sealing Tape on top, Breathable Tape on bottom.
• Use perforated tape only on the bottom edge for optimal condensation drainage.
• Ensure surfaces are clean and dry for maximum adhesive performance.
