Three new polycarbonate glazing options are available for the LIGHTWALL 3440 interlocking translucent wall panel system from Exterior Technologies Inc. (EXTECH): Anti-Reflective, Infrared-Blocking and Anti-Graffiti.
- Anti-Reflective – When high-efficient light transmission is paramount for a building's design, EXTECH offers anti-reflective polycarbonate glazing. Systems using this UV matte option facilitate a better distribution of light throughout a building's interior, while reducing reflections and glare. This option is also ideal for entertainment venues that want to project high-resolution images and lighting effects onto a translucent backdrop.
- Infrared (IR) blocking – When high light levels and solar control are equally important, EXTECH provides polycarbonate glazing with an external surface that filters out unwanted IR and UV waves. EXTECH systems use this material to reduce solar heat gain, ensure comfortable interior temperatures, protect interior finishes from accelerated fading, reduce demand on the HVAC system and save on electric lighting costs.
- Anti-Graffiti – When a project is in a high-traffic area and is at risk of damage or vandalism, EXTECH can enhance daylighting systems with anti-graffiti glazing that resists vandalism and scratching. Anti-graffiti glazing is also more resistant to natural weathering and typical chemicals, and is easier to clean.
In addition to these functional glazing choices, EXTECH's LIGHTWALL systems contribute to commercial buildings' aesthetic, performance, and sustainability goals. Lightweight and easy to install, the LIGHTWALL system helps construction teams facing condensed schedules, and facility managers seeking low-maintenance longevity.
"As our most popular product, the LIGHTWALL 3440 offers beauty, durability and economy with vertical panels that can extend up to 54 feet long and eliminate leak-prone horizontal joints," says EXTECH Director of Product Application and Development Kevin Smith, R.A. "Our LIGHTWALL system does not require framing members within the field of the glazing, which allows for a clean, modern architectural aesthetic."
In addition to enhancing a building's appearance, the 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 LIGHTWALL 3440 possesses some of the highest performance numbers in the industry due to its advanced framing. These attributes support energy efficiency and sustainability goals, such as the U.S. Green Building Council's LEED rating systems.
Smith adds, "The diffusing characteristics of the cellular polycarbonate reduces dependence on electric lighting and reduces solar heat gain into the building envelope, as well as reduces light pollution emanating from the building. Because it is a dry-glazed system, VOC emissions also are reduced."
LIGHTWALL 3440 also uses highly insulating, 100 percent recyclable, 40 mm structural cellular polycarbonate and 38.95 percent recycled aluminum framing manufactured in Pittsburgh.
