Equalite Select Insulation Board is a Stone Wool (Mineral Wool) Insulation Board (as per CAN/ULC-S702) featuring geometrically defined drainage cavities on the back side of the insulation board, intended for use in Equalite family of EIFS Systems. Equalite Select Insulation is supplied in sheets which are 610 mm (2ft) x 1220 mm (4 ft), in thicknesses from 50.8 mm (2”) to 152 mm (6”) in increments of 12.5 mm (1/2”) and available as 8 lbs/ft³ (128 kg/m³) density board. Equalite Select Insulation can be applied over any substrate approved for our Equalite family of EIFS Systems and attached by mechanical fasteners as specified. The sheets are not to be applied directly to framing members when part of any Equalite family of EIFS System. All test results given herein, or any of those in our EIFS Systems are specific to use Equalite Insulation. Substitution voids all tests results and systems warranties offered. Special aesthetic shapes supplied by others are not incorporated in the EIFS System warranty.

  • 10mm drainage cavity
  • GDDC Factor 25% (Geometrically Defined Drainage Cavity)
  • CI factor 0.70 RSI (R 4.0) per inch (Continuous Insulation)
  • Fire resistant
  • Non-combustible
  • Water and moisture resistant (repels water)
  • Does not rot or promote the growth of mildew, fungi or bacteria
  • Provides superior compressive strength for job site durability
  • Excellent sound-dampening characteristics

For use as the Exterior insulation in all Equalite family of EIFS Systems requiring drainage. The use of the Stone Wool (Mineral Wool) insulation is governed by the applicable building codes.
