A SUMMARY OF SPECIFICATIONS for 2-3/4" (70mm) and 4" (100mm) unless noted.

Panel Width: 4' and 5' (1220mm and 1524mm) standard. Other widths from minimum 1' (300mm) up to 5'0" (1524mm) are optional and cost more.

Panel Length: 3' to 20' (914mm to 6096mm) standard, 16' max. (4880mm) for Skyroof® systems; lengths may be more limited for optional grid patterns; FM, windborne debris, and ATFP designs.

Panel Thickness: 2-3/4" (70mm) standards; and 4" (100mm) optional. NOTE: 1" (25mm) for window glazing only is custom. NOTE: Aerogel insulated panels are 2-3/4" (70mm) only.

Weight: Most panels and systems weigh under 3 p.s.f. (14.65 kg/m2).

Color: Standards are Crystal, White; Optional Kal-Tint faces; translucent insulation can be virtually any color to create dazzling results. White only available for extra-high-impact options.

Surface Texture: Flat is standard.

Standard Grid Patterns: Nominal grid size — 12" x 24" (300mm x 600mm) standard; 8" x 20" (200mm x 500mm) optional for flat and curved panels. Other designs and grid sizes available and may be required for some optional panel types. Please note that spans will vary with different grid patterns. Consult factory.

Materials: Translucent FRP faces. Other options include opaque faces, windows (HC2000 Thermal Break) (E-Series) and louvers, aluminum grid, composite grid, fiberglass or aerogel insulation, aluminum and thermally broken installation systems.

High-Performance Aluminum Architectural Coatings: Corrosion-resistant finishes in standard and custom colors. View color samples.

U-Value Range: .53 to .05 (U-value SI conversion: 1.0 w/m2k=0.176 Btu/(hr / ft2 / °F)) for panels; NFRC system certification range .43 to .10. View NFRC values chart.

Light Transmission: 0 to 63%. View chart.

Solar Heat Gain Coefficient (SHGC): 0.10 to 0.65. View chart.

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 at even higher resistance.

Chemical Resistance: Most anything allowed by EPA and OSHA will not affect the standard panel systems.

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: : 31 dB to 35 dB depending on panel thickness and insulation type.

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 (SWRI). 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 and exterior 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 and the European Technical Community; 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 20-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.

NEW! Tested assemblies by AAMA 1503.1-09 "Test Method for Thermal Transmittance and Condensation Resistance Factor of Windows, Doors and Glazed Wall Sections". Panel Resistance Factor (CRF) of 81 demonstrates the superior performance of the Kalwall Thermally Broken I-beam. Overall U-factor was 0.19, including vision glazing.


NFRC Certified U-Factors and Solar Heat Gain Coefficients (SHGC)

All projects will be quoted on the basis of the NFRC certified system U-factor. For identification purposes we will still refer to the panel U-factors based on the NFRC 100 testing of the panel alone. The important distinction is that the certified U-factors are based on a model of the system, 79" x 79" and consist of 2 panels, a center batten as well as head, sill and jamb members. Most site-built window wall, curtainwall, sloped glazing and skylight systems are modeled at this size, allowing direct product comparisons.

  1. Other combinations available.
  2. Approximate values by ASTM E-972. Light transmission values over 30% not recommended for most applications.
  3. At 0° incident angle. Bold values are NFRC Certified, others are calculated based on tests. Shading Coefficient (SC) is equal to 1.15 times the Solar Heat Gain Coefficient (SHGC). Refer to NFRC Table for complete NFRC System Values.
  4. U-values determined by NFRC test method (ASTM C-1363, E-1423 and C-1199 or simulated at certified lab). Expressed as Btu/hr/ft2/°F for aluminum grid / thermally broken grid, nominal 12" x 24" (300mm x 600mm). Perimeter aluminum excluded. Test temperature at 15 mph wind (6.7 m/s): 0°F (-18°C) cold side and 70°F (21°C) warm side.
  5. SW, Type A and White High-Impact face sheets are similar in light transmision and solar heat gain properties.

Check with Technical Services Department for further clarification. Since this table is of a very technical nature, please consult your heating and ventilation engineer for proper interpretation.
