Thermax™ 4-Year IR/AC Greenhouse Film — 6mil, 50ft x 100ft, Clear

Superior Thermal Performance for Year-Round Growing — Thermax™ IR/AC Greenhouse Film, 50ft x 100ft

Thermax™ 4-Year IR/AC Greenhouse Film combines infrared heat retention and anti-condensation technology in a single 6-mil poly film, delivering superior thermal efficiency and a condensation-free growing environment. This 50ft x 100ft roll covers 5,000 square feet of greenhouse or growing structure surface, making it an ideal choice for commercial growers who demand maximum light transmission, energy savings, and a dry, healthy canopy environment throughout the growing season.

The IR (infrared) layer retains heat within the growing space at night, reducing heating costs and protecting crops during temperature swings. The AC (anti-condensation) treatment causes water droplets to sheet off the film's inner surface rather than dripping onto plants — reducing disease pressure, crop losses, and the labor cost of managing condensation-related problems in enclosed growing structures.

Key Features & Benefits

• 4-Year UV Stabilization: Rated for 4 years of continuous outdoor use — provides long-term return on investment for greenhouse covering applications without annual replacement costs.
• 6-Mil Thickness: Heavy-gauge 6-mil construction delivers durability against wind, hail, and physical wear in demanding outdoor and semi-outdoor growing structure applications.
• Infrared (IR) Heat Retention: IR-additive layer reflects radiant heat back into the growing space at night, reducing overnight temperature drops and heating energy requirements for year-round growing operations.
• Anti-Condensation (AC) Treatment: Hydrophilic inner coating causes condensation to sheet down the film rather than drip onto plants — significantly reducing botrytis, mildew, and other moisture-driven disease pressure.
• 50ft x 100ft Coverage: 5,000 square feet of premium greenhouse film per roll — sized for commercial bays, hoop houses, and full-coverage growing structure applications.
• High Light Transmission: Clear formulation maximizes natural light delivery to the crop, supporting photosynthesis and plant development throughout the growing season.

Who Should Use Thermax™ IR/AC Greenhouse Film

Commercial greenhouse operators, hoop house growers, and large-scale controlled environment agriculture producers who need maximum thermal efficiency combined with anti-condensation performance. Ideal for year-round growing operations in climates with significant temperature variation or high humidity environments where condensation management is critical to crop health.

Installation & Compatibility

Suitable for use on commercial greenhouse structures, Quonset hoop houses, gothic-profile greenhouses, and other covered growing structures. Install with the AC-treated surface facing inward (toward the crop) for anti-condensation performance. Use appropriate greenhouse poly clips and wiggle wire to secure the film to the structure frame. Overlap seams by a minimum of 12 inches and seal with UV-stabilized greenhouse tape where required.

Frequently Asked Questions

How long will this film last outdoors?

Thermax™ is rated for 4 years of UV-stabilized outdoor performance under normal greenhouse covering conditions. Actual service life may vary with climate, UV exposure levels, and installation quality.

Which side of the film faces inward?

Install the film with the anti-condensation (AC) treated surface facing the interior of the growing structure. The AC coating causes water to sheet down and away from the crop rather than dripping as isolated drops.

Does the IR layer affect plant light levels?

The IR additive is designed to be spectrally selective — it retains long-wave infrared (heat) radiation while maintaining high transmission of photosynthetically active radiation (PAR) for healthy plant growth.

Can this film be used for double-layer inflation greenhouse systems?

Thermax™ is suitable for single or double-layer applications on compatible greenhouse structures. For double-layer inflation systems, verify compatibility with your specific greenhouse design and inflation blower specifications.
