Green-tek GT IR/AC MAX 4-Year Greenhouse Film - 6mil - 40ft x 100ft - 75% Diffusion

4-Year Film Combining IR Heat Retention, Anti-Condensate Coating, and High Diffusion

A basic clear greenhouse film covers the structure but leaves heat retention, condensation, and light diffusion to chance. Green-Tek GT IR/AC MAX addresses all three in one 6mil film: infrared-blocking additives reduce nighttime heat loss, an anti-condensate coating channels moisture into a thin runoff film instead of dripping droplets, and a diffusion rating scatters direct sunlight into soft, even canopy-penetrating light.

Supplied and distributed by Green-Tek at 40ft x 100ft per roll with a 91% light transmission rating and 650g dart impact strength, GT IR/AC MAX is built for commercial greenhouse operators who want a feature-complete single-layer film rather than stacking separate additive treatments.

Key Features & Benefits

• Infrared (IR) Heat Retention: Thermal-blocking additives reduce nighttime heat loss through the film, lowering heating energy consumption.
• Anti-Condensate (AC) Coating: Directional condensation control minimizes dripping onto crops, reducing disease pressure from overhead moisture.
• 91% Light Transmission with High Diffusion: Scatters direct sunlight into soft, even illumination that penetrates deeper into the plant canopy.
• Bee-Compatible Light Spectrum: Formulated to support pollinator visibility and activity for crops relying on bee pollination.
• 650g Dart Impact Strength: Strong resistance to puncture from hail, branch impact, and installation stress for a 4-year service life.

Who Should Use This

Commercial greenhouse operators who need maximum light transmission, energy efficiency, and crop protection in a single 4-year film are the direct fit for GT IR/AC MAX, particularly for year-round production of vegetables, ornamentals, and specialty crops.

Green-Tek, Inc., headquartered in Beloit, Wisconsin, distributes GT IR/AC MAX as its most feature-complete single-layer greenhouse film, alongside its standard GT4 clear film and ThermaGlas polycarbonate lines.

Frequently Asked Questions

What does the anti-condensate (AC) feature do?

The anti-condensate additive modifies the film's surface energy so condensation forms as a thin, even water film that flows down the sheet rather than collecting into droplets that fall onto crops. This reduces overhead drip, which can cause crop damage and disease spread.

How does infrared (IR) retention improve energy efficiency?

The IR-blocking additives reflect a portion of the greenhouse's long-wave thermal emissions back into the growing space at night rather than letting them pass through the film. That passive thermal retention lowers the temperature differential between inside and outside, reducing nighttime heating requirements.

What does the diffusion rating mean for plant growth?

A high diffusion rating means the film scatters a large share of incoming direct sunlight into diffuse radiation rather than passing it through as a direct beam. Diffuse light penetrates deeper into the plant canopy, improving photosynthesis efficiency across the whole plant and reducing leaf burn on upper canopy surfaces.

When would I choose GT IR/AC MAX over standard GT4 clear film?

Choose GT IR/AC MAX when nighttime heat retention, condensation control, and diffused light are priorities for your crop and climate. Choose standard GT4 when a straightforward, high-transmission clear film meets your needs at a lower cost.
