Green-tek Aluminet Outdoor Shade Cloth - 30% Shade - Sold by the Square Foot

Green-tek Aluminet Outdoor Shade Cloth - 30% Shade

Green-tek Aluminet Outdoor Shade Cloth is a metallized HDPE knitted screen engineered to regulate greenhouse temperature, improve energy efficiency, and protect crops from light stress. The double-sided reflective design diffuses light evenly during the day to prevent heat stress, and provides passive frost protection at night by reducing radiative heat loss. Proven to reduce heating energy use by over 50%, Aluminet is a durable, recyclable fabric that delivers long-term value for greenhouse climate management.

Key Features & Benefits

• 30% shade / 70% light transmission: Optimized for crops and environments requiring 30% reduction in direct solar radiation while maintaining strong photosynthetically active radiation (PAR).
• Metallized double-sided reflective design: Reflects excess solar radiation away from the crop during the day to reduce heat stress, and reflects heat back toward plants at night to provide passive frost protection.
• Reduces heating energy use by over 50%: The reflective thermal barrier dramatically reduces heat loss from the growing environment, lowering heating costs in cooler months.
• UV-resistant HDPE knitted construction: Lightweight, long-lasting fabric that resists UV degradation for multi-season durability.
• Recyclable material: Aluminet can be recycled at end of service life, reducing environmental impact compared to non-recyclable shade materials.
• Sold by the square foot: Order exactly the coverage area you need without waste.

Who Should Use This

Green-tek Aluminet is the preferred shade cloth for commercial greenhouse operators and serious growers who need both daytime heat stress reduction and nighttime thermal retention in a single product. The 30% shade level suits crops that require moderate light regulation while maintaining strong growth rates. Its energy-saving thermal properties make it especially valuable in climates with both hot summers and cold winters.

Compatibility

Suitable for interior greenhouse shade screen systems, exterior shade structures, and overhead canopy installations. Compatible with standard greenhouse shade cloth hanging and tensioning hardware. Can be secured using Green-tek Knitted Shade Cloth Grommets, Shark Bite Gripper Fasteners, or standard cable and clip systems. Sold by the square foot - contact your supplier for minimum order quantities and roll widths.

Frequently Asked Questions

How does Aluminet provide frost protection at night?

The metallized reflective surface of Aluminet reduces radiative heat loss from the crop and surrounding air by reflecting thermal infrared radiation back downward rather than allowing it to escape through the greenhouse glazing. When deployed as a thermal screen at night, this passive heat retention can raise nighttime temperatures by several degrees - reducing frost risk and heating costs simultaneously.

What is the difference between Aluminet and knitted black shade cloth?

Black shade cloth absorbs solar radiation and converts it to heat at the fabric surface. Aluminet reflects solar radiation away from the growing area instead of absorbing it, resulting in lower temperatures beneath the screen on hot days. Aluminet also provides the nighttime thermal retention benefit that black shade cloth cannot, making it a more versatile year-round climate management solution.

Can Aluminet be used outdoors?

Yes. Green-tek Aluminet is specifically described as an outdoor shade cloth and is UV-resistant for long-term exterior applications. It is commonly used on exterior shade structures, over outdoor beds, and as a shade layer on the exterior of greenhouse glazing.

Is Aluminet sold in fixed roll sizes or by the square foot?

Aluminet is sold by the square foot, allowing you to order precisely the coverage area required for your application. Contact your Cannavista representative for available roll widths and minimum order quantities.
