New 9-wall, energy efficient and highly aesthetic sheets for flat glazing solutions to replace multipane glass windows

To address drawbacks associated with installing multipane glass windows, SABIC Innovative Plastics has developed a new 9-wall Lexan* Thermoclear* sheet as an excellent candidate for applications such as flat glazing of sunrooms, conservatories, and rooflights, shopping centers, office buildings, and factories. This new glazing solution reduces heating and cooling costs and cuts energy usage, CO2 emissions to benefit the environment. The new Lexan Thermoclear sheet is a unique, 9-wall product and the first multiwall sheet in the glazing industry to deliver a U-value of less than 1.0 W/ m2K. The sheet offers superior insulation properties vs. multi-pane glass, plus light weight, extremely high impact resistance, stiffness and ultra violet (UV) protection. Moreover, the 9-wall X-structure of the new material creates more air pockets between the outside environment and the interior of the building, while enhancing strength and stiffness which enables material deliver industry-leading energy efficiency. A reduction in U-value of 0.1 W/m2K can yield annual energy savings of up to 1.5 cubic meters of natural gas. The company claims installing 50mm Lexan Thermoclear sheet with a U-value of 0.99 W/m2K instead of double-pane glass with a U-value of 1.4 W/m2K could save up to 4.40 Euro per square meter of window surface each year. Available in opal white, solar control green and transparent, both the sides of the sheet are treated with proprietary UV protection against outdoor weathering to help ensure long-term optical quality and high light transmission. In accelerated 4,000-hour weathering tests (DIN53387 / ASTM G26) - comparable to 10 years of outdoor exposure in moderate climate conditions - results obtained by the company demonstrate Lexan Thermoclear sheets' superior ability to maintain color, light transmission and impact strength vs. competitive products.
