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

Wider-Coverage Foil Seal for Overlap Seams and Broader Polycarbonate Profiles

Standard 1in tape covers a single panel edge well, but overlap seams and wider polycarbonate profiles need more adhesive surface area for a reliable seal. Green-Tek's 2in Aluminum Tape delivers that extra coverage, sealing the top ridge edges of multiwall polycarbonate sheets with the same moisture-impermeable, UV-stable aluminum foil as the standard tape, just twice as wide.

The 150ft roll covers multiple panels or overlap joints in one continuous run, making it a practical choice whenever the standard 1in width falls short of the coverage a specific installation needs.

Key Features & Benefits

• 2in Wide Coverage: Twice the width of standard tape, for wider profiles, lap joints, and extra sealing margin.
• Aluminum Foil Construction: Moisture-impermeable, UV-stable seal that lasts the service life of the installation.
• 150ft Roll: Enough tape for multiple panels or a full greenhouse installation from one roll.
• Silver Finish: Reflects UV at the sealed edge and matches the look of standard Green-Tek tape products.

Who Should Use This

Greenhouse builders and growers installing Green-Tek ThermaGlas twinwall or triplewall polycarbonate who need a 2in sealing width, whether for overlap seams, structural edge protection, or profiles where the standard 1in width is insufficient.

Frequently Asked Questions

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

Use it when you need wider coverage for broader polycarbonate profiles, when creating overlap seals between sheets, or when extra adhesive surface area will improve the weather seal at a structural connection. For standard 8mm twinwall edge sealing alone, either width works.

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

No, the bottom eave edge should use ventilated tape or U-Profile so condensation can drain out of the channels. Solid tape at the bottom traps moisture inside the cells, leading to algae growth and reduced light transmission over time.

Is this tape UV resistant for permanent outdoor use?

Yes, the aluminum foil construction is inherently UV stable and doesn't degrade or lose adhesion from sun exposure over the life of the installation, making it suitable for permanent exterior use. It performs the same way in this wider format as the standard 1in tape.

How do I get the best adhesion when applying this tape?

Clean and dry the polycarbonate edge surface first, then press firmly across the full width to eliminate air pockets. Applying the tape before the sheet goes into the greenhouse frame gives the easiest access for a complete seal.
