Why Choose Lexan Thermoclear 15
Unmatched Durability
Guaranteed to outperform and outlast all other brands, the Lexan Thermoclear 15 multiwall sheet is engineered for longevity and resilience. This sheet is virtually free from yellowing and will not lose impact strength due to weathering. It maintains high clarity and comes with an industry-leading 20-year extended warranty.
Over a 20-year period, this sheet will not lose more than 4% in light transmission or experience a change greater than 5 Delta from the original yellowing index of 0. The warranty also covers breakage caused by hail for up to twenty years, offering 100% full replacement value for the first fifteen years.
High Light Transmission
The proprietary UV protection on the sheet’s outer surface guarantees long-term optical quality and high light transmission while providing superior resistance to outdoor weathering. This unique surface treatment helps maintain the toughness of the polycarbonate material, with UV protection available on one or both sides of the sheet.
Outstanding Impact Performance
The Lexan Thermoclear 15 panel is virtually unbreakable, boasting impact resistance that is 10 times stronger than acrylic and 200 times stronger than glass. Even when exposed to harsh weather conditions and extreme temperatures ranging from -40°F to +240°F, this sheet maintains its structural integrity over time.
DripGard™ Feature
Designed with a specially developed anti-condensate coating, the DripGard feature creates an optimal greenhouse environment. This anti-drip characteristic reduces moisture buildup by allowing condensation to spread into a thin film rather than forming droplets, which can lead to disease, burn spots, crop spoilage, and loss of light transmission.
High Light Diffusion
The advanced polymer technology of the Softlite multiwall sheet effectively scatters light, eliminating greenhouse “hot spots.” This even distribution of light reaches both top and bottom leaves, providing more usable energy to plants, enhancing color vibrancy, and virtually eliminating shadows. With 100% light diffusion, these sheets are an excellent choice for greenhouse glazing, ensuring uniform light delivery essential for successful production and higher crop yields.
Excellent Thermal Properties
The hollow channels within the panel’s structure offer exceptional thermal insulation, sound insulation, and impact energy absorption. These properties not only enhance a building’s winter heating efficiency but also help reduce utility costs.
Top Fire Ratings
Polycarbonate panels exhibit excellent flame-retardant properties. Classified as CC1 according to ASTM D-635 and rated Class A for interior surface materials under ASTM E-84, multiwall polycarbonate sheets offer higher fire ratings than acrylic. This results in lower insurance rates and enhanced safety.
Established Excellence
As a trusted brand for over 40 years, the Lexan Thermoclear 15 panel is an ideal glazing solution for various horticultural, architectural, industrial, residential, and agricultural applications.
Warranty Information
Our multiwall sheet is backed by a full 10-year warranty against yellowing and a 5-year warranty for breakage caused by hail.
