Flexlite Select
Flexible Moisture Managed Exterior Insulation & Finish System (Adhered)

Flexlite Select is an exterior insulation and finish system consisting of a moisture barrier, a 10mm geometrically defined drainage cavity, expanded polystyrene insulation, glass fibre-reinforcing mesh, base coats, and a finish texture coat which can be selected from any one of the available Durex Architectural Coatings.

  • CAN/ULC S716 compliant
  • CCMC evaluated (13103-R)
  • Easy installation
  • Positive drainage
  • Lightweight
  • Versatile
  • Flexible
  • Continuous Insulation – CI Factor = 0.65 RSI/in (Type 1 EPS)   0.7 RSI/in (Type2 EPS)

Flexlite Select is primarily suitable for residential work.
