Kalwall products have long been proven to stand up in the harshest conditions, including hurricanes and tornadoes, and the recent certification from National Accreditation and Management Institute of the E-Series window once again confirms that.
The E-Series window manufactured at Kalwall’s Candia Road facility in Manchester, N.H., passed Missile D testing, absorbing the impact of 8-foot long 2 by 4 shot out of a missile at 50 feet per second and still remaining weather tight after impact.
The certification allows the window to meet the stringent standards of building codes in hurricane zones to resist large windborne debris. These codes affect buildings along the East Coast upwards of a mile and a half inland.
Kalwall translucent systems have previously been certified for hurricane resistance, but the E-Series windows allow the integration of clear vision glass with translucent panels. Kalwall is the only translucent system meeting these specifications.
Designers get all the benefits of Kalwall, such as controlled daylighting along with high insulation values, plus clear vision to the outside, an important component of LEED certification. The production of the windows at Kalwall’s Candia Road campus allows for a faster delivery and more custom designs.
The clear glazing is 5-feet wide and can be up to three feet high, offering a variety of options to designers. All are certified to TAS 201, 202, and 203 as well as ASTM E1886 and E1996 in fixed and project-out sash models.
Additionally, when properly installed, E-Series Windows meet the ADA (Americans with Disabilities Act) and UFAS (Uniform Federal Accessibility Standard) criteria. The window takes less than 5 lbs. (2.2 kg) of force to open and close and the single window handle is a comfortable curved, open loop design that can be effortlessly operated.
