More about this product

Kalwall is a translucent, structural sandwich panel which uses prismatic glass fibers embedded in the panels face sheets. The glass prisms refract sunlight to provide a balanced, diffuse wash of glare-free light. Kalwall offers a wide range of pre-engineered Skyroofs® including: shed roofs, ridge roofs, pyramids, barrel vaults, low-profile vaults.

  • Kalcurve® 180° and low-profile 90° come in one-foot curb width increments

Kalwall panels are extremely lightweight compared to glass, at less than 3 lbs/ft2, thus support framing requirements are minimized. Only thrust-bearing curbs designed to accommodate local live, snow and wind load designs are required. The rugged skylights are all mansafe and OSHA fall thru compliant, meaning no safety cages are required.


  • Standard, aluminum or thermally broken interlocking I-beam panel grid core
  • Standard or thermally broken aluminum Clamp-titeTM fastening system
  • U-factors range from 0.53 - 0.05 (3.01 to 0.28 W/m2K)
  • Solar Heat Gain Coefficients (SHGC) from 0.65 to 0.04
  • Visible Light Transmission (VLT) values from 3% to 50%
