Green-tek® 4-Year GT4 Greenhouse Film — 6mil, 20ft x 100ft, Clear

Reliable 4-Year Greenhouse Film Coverage, 6mil Clear, 20ft x 100ft Roll

Annual-replacement greenhouse film adds a recurring labor and material cost that compounds year after year. Green-Tek GT4 Greenhouse Film solves that with a UV-stabilized 6mil clear poly film rated for 4 years of continuous outdoor exposure, sized at 20ft x 100ft per roll, giving commercial greenhouse operators a durable covering that maximizes natural light delivery while protecting against the elements across multiple growing seasons.

Supplied and distributed by Green-Tek for commercial horticulture applications, GT4 balances high light transmission with the structural durability needed to withstand outdoor weather, supporting strong plant development from propagation through harvest.

Frequently Asked Questions

How long will GT4 film last on my greenhouse?

GT4 is UV-stabilized and rated for 4 years of outdoor performance under normal commercial greenhouse covering conditions. Actual service life can vary with local UV intensity, installation quality, and structural design.

Is this film suitable for double-layer inflation systems?

GT4 film is compatible with standard single and double-layer commercial greenhouse applications. Verify compatibility with your specific structure design and inflation system specifications before ordering.

What is the light transmission percentage of this film?

GT4 is rated at 92% light transmission per Green-Tek's own product documentation. That places it among the higher-transmission clear 6mil greenhouse poly films commonly available.

When should I cut this roll to fit my greenhouse dimensions?

Cut the roll to length once you've measured your structure and confirmed overlap requirements at the seams. Use a sharp utility knife or poly film cutter, and seal any cut edges with UV-stabilized greenhouse tape to prevent tearing.
