Impact: Standard exterior faces will withstand 70 ft.-lbs. impact. Optional hi-impact faces will withstand 230 ft.-lbs. (311J) impact, Hurricane-Resistant and Blast-Resistant Systems also available.

Chemical Resistance: Most anything allowed by EPA and OSHA.

Weathering: Kalwall's exterior face is made with innovative super-weathering and colorfast resins the full thickness... not a low-grade substrate overlaid with thin plastic film or gel to simulate weatherability. All standard exterior faces include a permanent glass veil erosion barrier to prevent "fiber bloom"! This is just one built-in quality bonus not offered by look-alikes!

Sound: Average transmitted by test, excellent performance.

Fire: Although some Kalwall panels contain combustible binder resins (ignition temperature greater than 800ºF), they will withstand a 1200ºF flame for one hour with no flame penetration. Kalwall panels pass the Class "A" Burning Brand Test (ASTM E-108). A special configuration of Kalwall is a UL Listed Class A Roof system. All interior faces are 1 in. or less Burn Extent, by ASTM D-635. Several categories of interior flame-spread/smoke developed by UL 723 tunnel tests, including Class 1, are available. Kalwall is listed by: ICC #PFC-1705; several state and local areas and U.L. Canada. British Standard 476, Parts 3, 6, 7. FM Class I and NFPA 268 – Radiant Panel Test-Exterior Walls. Whenever reference is made to fire tests, the numerical rating is not intended to reflect hazards presented by this or any other material under actual fire conditions.

Bond Strength: Panels are a specially engineered composite designed for maximum architectural and structural life. Panels and adhesives are tested according to the stringent requirements of "Criteria for Sandwich Panels" issued by ICC (International Code Council) and must pass severe tensile and shear tests before and after numerous exposure conditions. Before specifying an alternate, insist on actual field proof of bond integrity over a 25-year period. Caution is urged in accepting "look-alikes" as equivalents.

Expansion: The coefficient of linear thermal expansion of Kalwall is 1.24 x 10^-5 in/in/ºF. (2.23 x 10^-5 mm/mm/ºC). An 8' panel will expand lengthwise approximately 1/8" when the temperature rises 100ºF or a 2 m long panel will expand approximately 2 mm when the temperature rises 40ºC.

NFRC Certified U-Factors as of 2004:

For identification purposes, we refer to the panel U-factors based on the 1994 NFRC test. Certified U-factors are based on a model of the system, 80" x 80" and consist of 2 panels, a center batten as well as head, sill and jamb members. All site-built window wall, curtainwall, sloped glazing and skylight systems are modeled at this size, allowing direct product comparisions.

Kalwall Light Transmission, Solar Heat Gain Coefficients and U-Values For 2-3/4" (70mm) Panels

Contact us for info for 4" (100mm) and 1-9/16" (40mm) panels

Kalwall is a composite sandwich; various combinations are possible, and test data should be interpreted from this point of view. Consult Sales Service Department for further clarification. Since this table is of a very technical nature, please consult your heating and ventilation engineer for proper interpretation. Listed below are the light transmission, solar heat gain coefficients and U-values for some Kalwall Panel face sheet combinations. Others are available. Blue values indicate thermally broken panels.
