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

Infrared Heat Retention and Anti-Condensation Coating, 6mil 50ft x 100ft

Overnight heat loss through a single-layer greenhouse film drives up heating costs, and condensation that drips directly onto the canopy adds disease pressure on top of that. Thermax IR/AC Greenhouse Film addresses both in one 6mil covering: an infrared additive layer reflects radiant heat back into the growing space at night, while a hydrophilic anti-condensation coating on the inner surface causes moisture to sheet down the film instead of dripping onto plants below.

The IR layer is spectrally selective, so it retains long-wave infrared heat while still passing photosynthetically active radiation the crop needs. Rated for 4 years of UV-stabilized outdoor use, this 50ft x 100ft roll covers 5,000 sq ft and installs with the AC-treated surface facing the interior of the structure.

Key Features & Benefits

• Infrared (IR) heat retention — reflects radiant heat back into the space overnight, reducing heating energy needs.
• Anti-condensation (AC) inner coating — sheets moisture down the film rather than letting it drip onto the canopy.
• Spectrally selective IR layer — retains heat wavelengths while passing photosynthetically active light through to the crop.
• 4-year UV-stabilized rating — multi-season outdoor performance for commercial growing structures.
• 50ft x 100ft roll, 5,000 sq ft — 6mil clear film sized for large commercial greenhouse bays.

Who Should Use Thermax IR/AC

Growers in climates with cold nights or high humidity, running large-bay year-round operations where heating cost and condensation-driven disease pressure are both concerns, are the direct fit for this larger Thermax IR/AC roll.

About AT Films / Berry Global

Thermax is manufactured by Berry Global under the AT Films brand, engineering IR and anti-condensation technology into the same film specifically for growers who need both thermal performance and condensation control across a range of bay sizes.

Frequently Asked Questions

How do I orient this film during installation?

Install with the anti-condensation treated surface facing the interior of the growing structure. That orientation is what causes water to sheet down and away from the crop rather than forming drips.

Does the IR layer reduce light reaching the plants?

No, the IR additive is spectrally selective, targeting long-wave infrared heat radiation while maintaining transmission of the photosynthetically active light plants use for growth. The two functions work on different parts of the light spectrum.

Why choose the 50ft x 100ft size over a smaller roll?

A single 50ft-wide roll covers a large greenhouse bay with fewer seams than piecing together narrower rolls, which reduces installation labor and minimizes light loss at overlap zones. Match the roll width to your structure's bay span before ordering.

Can this film be used on a double-layer inflation system?

Thermax is suitable for single or double-layer applications on compatible greenhouse structures. Verify compatibility with your specific structure design and inflation blower specifications before installing.
