Green-tek® 4-Year GT4 Greenhouse Film — 6mil, 36ft x 150ft, Clear

Reliable 4-Year Greenhouse Coverage Built for Commercial Growing — Green-tek® GT4, 36ft x 150ft

The Green-tek® GT4 4-Year Greenhouse Film delivers dependable, long-lasting coverage for commercial greenhouses, hoop houses, and covered growing structures. This 36ft x 150ft roll of 6-mil clear poly film is UV-stabilized for 4 years of continuous outdoor exposure, providing growers with a cost-effective and durable covering solution that maximizes natural light delivery to the crop while protecting against the elements.

Engineered by Green-tek for commercial horticulture applications, the GT4 film balances high light transmission with the structural durability needed to withstand outdoor weather conditions across multiple growing seasons. Its clear formulation ensures that crops receive maximum photosynthetically active radiation (PAR) throughout the growing season, supporting strong plant development from propagation through harvest.

Key Features & Benefits

• 4-Year UV Stabilization: UV-inhibitor package rated for 4 years of outdoor service — delivers multi-season durability without the annual replacement costs of shorter-rated films.
• 6-Mil Construction: Heavy-gauge 6-mil thickness provides resistance to wind, abrasion, and physical wear in outdoor commercial greenhouse and hoop house applications.
• High Light Transmission: Clear formulation delivers maximum natural light to the crop — supporting photosynthesis and healthy plant development across all growth stages.
• 36ft x 150ft Roll Size: 5,400 square feet of coverage per roll — sized for commercial greenhouse bays, high tunnel structures, and covered row crop applications.
• Commercial-Grade Performance: Formulated by Green-tek to meet the durability and performance standards of professional commercial horticulture operations.
• Cost-Effective Multi-Season Coverage: 4-year rating reduces the total cost of greenhouse covering over time compared to annual replacement films, delivering strong ROI for commercial operations.

Frequently Asked Questions

How long will GT4 film last on my greenhouse?

Green-tek® 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.

What is the light transmission percentage of this film?

Refer to Green-tek's technical data sheet for specific PAR and total light transmission values for the GT4 film. Clear 6-mil greenhouse poly films typically transmit 85-90% of available light, though exact values vary by formulation.

Can I cut this roll to fit my greenhouse dimensions?

Yes — greenhouse poly film can be cut to length as needed for your structure. Use a sharp utility knife or poly film cutter, and seal any cut edges with UV-stabilized greenhouse tape to prevent tearing.
