ADVERTORIAL: COVER STORY extensive on the market today, SABIC’s offering include hundreds of possible combinations of structures, colours, coatings and finishes. LEXAN™ sheet helps architects and builders to meet tough challenges in demanding environments. Applications for LEXAN™ sheet include atriums, canopies and walkways, greenhouses, skylights and overhead glazing, industrial glazing solutions, pool cover enclosures, partition walls, mega roof structures, stadium cladding and roofing, security glazing, and storm protection, to mention a few. SABIC’s robust product LEXAN™ THERMOCLEAR™ sheet. creating a more aesthetically pleasing working or living environment while saving on electricity for artificial lighting. However, while letting light in, the material also offers ultraviolet (UV) protection for occupant health and exceptional thermal insulation to enhance energy conservation. With new LEXAN™ THERMOCLEAR™ nine- wall sheet, U-values as low as 0.89W/m 2 K (acc. ISO 10077 test) can be achieved surpassing the insulation performance of double – and even triple – pane glass. Improved insulation reduces the use of energy for heating during cold periods and air conditioning during hot periods. The use of specialised PC sheet that blocks infrared radiation (IR) can reduce the build-up of interior heat for lower energy consumption, while permitting plenty of light. This material is an excellent choice for skylights, walkways and roof domes where it is important to admit high light levels while reducing heat that would otherwise require air conditioning. LEXAN™ THERMOCLEAR™ sheet also conserves energy in handling. This lightweight material – at least three times lighter than a comparably sized glass panel with the same thermal insulation value – saves fuel in shipping and installation. Less weight also allows LEXAN™ sheet to be supported by lighter-weight glazing bars and substructure, reducing the amount of support material required. Even during manufacturing, LEXAN™ sheet offers environmental advantages over glass. Typical operating temperatures during the sheet extrusion process are in the 240°C range. Therefore, the energy used during the extrusion process in which LEXAN™ resin is converted into LEXAN™ sheet, is just a fraction of the energy needed to manufacture the flat glass that goes into the same building and construction applications. During the LEXAN™ sheet extrusion process, up to 15% of recycled content is used to produce virgin material. By incorporating LEXAN™ sheets into designs, architects can now make any building more sustainable affording them the opportunity to tap into the green building market. Advanced properties for demanding applications Decades of proven performance and global expertise For more than a quarter of a century, LEXAN™ PC sheet glazing materials have helped to deliver measurable returns on investment through ease of installation, lower insurance costs through resistance to break-ins, weather damage and vandalism; and less need for replacement due to UV degradation and weathering. Most of the LEXAN™ products are covered by a minimum 10-year limited warranty against excessive yellowing, loss of light transmission and loss of strength due to weathering. Building on a legacy of leading-edge products, SABIC continues to push forward with state-of-the-art materials designed to support customers to achieve competitive differentiation through new designs, safety and durability. Virtually unbreakable, high optical quality, solid and multiwall LEXAN™ sheets with highly specialised properties are often a top choice for answering the specific needs of a variety of structures.
