Greenhouse Lexan^* Thermoclear^*

^*Trademarks of Sabic Innovative Plastics^TM

Overview

Sabic Innovative Plastics^TM Lexan* Thermoclear* sheet range combines the impact strength and superior light transmission of polycarbonate, with excellent thermal insulation and spanning capabilities. Lexan Thermoclear sheet features a proprietary UV surface treatment that is superior to traditional UV protective technologies. These features make Lexan Thermoclear an excellent, cost-effective alternative to materials such as glass.

Features

• Outstanding hail impact resistance.
• Comprehensive written warranties.
• UV protected glazing profiles.
• Easily curved.
• Excellent thermal insulation.
• Light weight.
• Minimal glazing bars for maximum light transmission.
• Customised coatings and gauges.

Testimony

“I have been growing roses under my greenhouse clad in Lexan Thermoclear for over 18 years. I now experience better yield from 21,000 roses, as I did from 35,000 roses growing in broad-acre crops! I would recommend the product to any grower seeking maximum yield, long life-span and the peace-of-mind of a storm resistant product!”

Superior Weatherability

Lexan Thermoclear SunXP sheet, in addition to the inherent properties of the Lexan Thermoclear Plus range, offers UV protection as standard on both sides, but with even higher resistance to UV radiation, yellowing and loss of light transmission. Lexan Thermoclear SunXP sheet comes with a 15 year written limited warranty. 

Anti-Drip 

Lexan Thermoclear Dripgard sheet features a specifically developed hydrophilic coating on the inner surface which reduces the formation of condensation droplets, thus helping to prevent crop spoilage in commercial greenhouses. This coating technology can be combined with either the Lexan Thermoclear Plus sheet, Lexan Thermoclear SunXP sheet or Lexan Thermoclear Easy Clean sheet.

Self-Cleaning 

Lexan Thermoclear Easy Clean sheet is the world’s first self-cleaning polycarbonate sheet. UV protected on both sides, Lexan Thermoclear Easy Clean sheet features a unique hydrophobic coating on the outside surface that reduces the surface tension of polycarbonate and increases the contact angle of water to the sheet. This causes large droplets to form and wash away dirt, leaving the sheet almost spotless. Furthermore it stays clean longer, thereby improving light transmission levels and reducing the frequency and the associated cost of cleaning.

High Impact Strength

The inherent properties of polycarbonate give Lexan Thermoclear up to 250 times the impact strength of tempered glass, resulting in greater resistance to hail and stones.

UV Protected Both Sides of Sheet

Both sides of the sheet have Sabic Innovative Plastics^TM patented surface coating technology to provide high resistance to yellowing, hail and loss of light transmission. This feature eliminates the problem of sheets being installed with an unprotected surface exposed to the weather with resultant UV damage.  Angle cuts can be reversed, so there is also an economic gain when cutting requirements are high.

Spanning / Weight

The multiwalled structure of Lexan Thermoclear allows the sheeting to display excellent spanning capabilities. When compared to glass, this can mean far fewer glazing bars, thus increasing light transmission and reducing costs. 

Lexan Thermoclear is also up to 8 times lighter than 4mm float glass. The lighter weight results in a far less substantial structure being required to support the material, reducing costs and maximising light transmission. 

Thermal Insulation 

The multiwalled structure of Lexan Thermoclear sheeting, allows the product to display excellent thermal insulation properties. This results in high energy savings, especially important in heated greenhouses. Greater insulation also means lower levels of condensation.

* The K-Value for 4mm float glass is 5.8 W/m².K.

Light Transmission 

Lexan Thermoclear sheet displays excellent light transmission and clarity. With GE’s patented surface coating technology, Lexan Thermoclear sheet is also warranted to maintain a high light transmission level over a long period of time.

Note: Other factors also contribute to overall light transmission such as the level of supporting structure, orientation and the shape of the structure itself. Unlike glass, Lexan Thermoclear sheet features excellent spanning capabilities to reduce supporting structure, and can be curved to minimise shaded areas.

Curving

Lexan Thermoclear sheet can be curved to a minimum radius, 175x the gauge. For example, 6mm sheeting can be curved to a 1050mm radius.

Sheet Sizes

Lexan Thermoclear sheet is available in structures from 4.5mm to 32mm. For the majority of greenhouses, 6mm, 8mm or 10mm gauges are used. Sheet widths are available up to 2100mm, with lengths available up to 11.8m. For stock availability, please contact your nearest Ampelite office.

Installation

The light weight of Lexan Thermoclear sheet makes installation easy and efficient. A range of installation options are available depending on the structure and application. Aluminum glazing bars with rubber gaskets are available, as well as translucent polycarbonate connecting bars. For more information on installation, please contact your nearest Ampelite office.

Warranty 

Sabic Innovative Plastics^TM Lexan* Thermoclear* patented surface coating technology allows Lexan Thermoclear sheet to display superior resistance to hail damage and loss of transmission. Lexan Thermoclear features a limited 10 year warranty against hail damage and a loss of light transmission of only 4% over the same period. A limited 15 year warranty is available for the new SunXP product.

For full warranty details, please contact your nearest Ampelite office.
