Green-tek Aluminum Tape - 2in x 150ft - Silver - For Polycarbonate Sealing

Green-tek Aluminum Tape - 2in x 150ft - Silver - For Polycarbonate Sealing

Green-tek's 2-inch Aluminum Tape provides a wider sealing surface for polycarbonate sheet installations where additional coverage is needed. Applied to the top (ridge) edges of multiwall polycarbonate sheets, it creates a permanent moisture-impermeable barrier that prevents dust, debris, insects, and moisture from entering the cellular channels. The 2in width is ideal for applications requiring broader coverage than the standard 1in tape, including wider profile sheets and overlap sealing.

Key Features & Benefits

• 2in wide coverage: Wider than the standard 1in tape - provides additional coverage for wider polycarbonate profiles, lap joints, and applications where extra sealing width is needed.
• Aluminum foil construction: Moisture-impermeable, UV-stable seal that lasts the service life of the polycarbonate installation.
• 150ft roll: Sufficient length for multiple panels or complete greenhouse installations.
• Silver finish: Reflective surface matches the aesthetic of standard polycarbonate installations and helps reflect UV at the sealed edge.

Who Should Use This

Used by greenhouse builders and growers installing Green-tek ThermaGlas twinwall or triplewall polycarbonate where a 2in sealing width is preferred. Also useful for overlap sealing, structural edge protection, or any application where the standard 1in width is insufficient.

Compatibility

Compatible with all Green-tek ThermaGlas 8mm twinwall and triplewall polycarbonate sheets. Use at the top (ridge) edge only - bottom edges require ventilated tape or U-Profile to allow condensate drainage.

Frequently Asked Questions

When should I use 2in tape instead of 1in tape?

Use the 2in tape when you need wider coverage for broader polycarbonate profiles, when creating overlap seals between sheets, or when sealing structural connections where additional adhesive surface area improves the weather seal. For standard 8mm twinwall edge sealing, either width can be used effectively.

Can this tape be used on the bottom edge of polycarbonate sheets?

No. The bottom (eave) edge should use ventilated tape or U-Profile to allow condensation to drain out of the channels. Using solid aluminum tape on the bottom edge traps moisture inside the cells, leading to algae growth and reduced light transmission over time.

Is this tape UV resistant?

Yes. The aluminum foil construction is inherently UV stable - it does not degrade or lose adhesion from UV exposure over the service life of the installation, making it suitable for permanent exterior applications.

How do I ensure proper adhesion?

Clean and dry the polycarbonate edge surface before applying tape. Press firmly across the full width of the tape to eliminate air pockets and ensure complete adhesion across all channel openings. Apply the tape before installing the sheet in the greenhouse frame for easiest access.
