EXTECH’s LIGHTWALL 3440® – Interlocking Polycarbonate Wall System

EXTECH's LIGHTWALL 3440® system features 40mm polycarbonate “tongue & groove” panels. The panels click together for clean appearance and easy installation. This system offers a host of benefits including energy savings via daylighting, outstanding insulating value, and high-impact resistance. The panels are environmentally friendly, made from recycled polycarbonate, and available in multiple colors and translucencies. Vertical panels extend up to 54 feet long to eliminate leak-prone horizontal joints.Backed with a 10-year warranty, the LIGHTWALL 3440 possesses some of the highest performance numbers in the industry due to its advanced framing. This system does not require framing members within the field of the glazing, which allows for a clean, modern architectural aesthetic. LIGHTWALL 3440 meets demanding performance specifications, including high wind loads, impact resistance, fire rating, air infiltration, water penetration, thermal (0.25 U-Factor) and structural performance. The diffusing characteristics of the cellular polycarbonate glazing provides energy-efficient daylighting, lowers dependence on electric lighting and reduces solar heat gain to keep people comfortable within the building envelope. Viewed from the exterior, these diffusing characteristics also reduce light pollution emanating from the building.LIGHTWALL 3440 uses highly insulating, 100 percent recyclable, 40 mm structural cellular polycarbonate glazing and 38.95 percent recycled aluminum framing. Because it is a dry-glazed system, VOC emissions also are reduced.EXTECH engineers and manufactures its daylighting products at its facility in Pittsburgh to ensure performance as specified. As part of its shop drawing and fabrication process, EXTECH ensures a weather-tight building envelope by pre-fabricating all the corner miters and sloped head/sill/jamb conditions to exact angles before shipping to the job site. This is a quality control measure to guarantee each piece fits precisely, without the need for field measuring and cutting. This substantially accelerates the installation process for construction teams and provides greater peace-of-mind for building owners.
