Quantum Select
Advanced-Drained Moisture-Managed Exterior Insulation and Finish System (Adhered)

Quantum Select is an exterior insulation and finish system consisting of expanded polystyrene insulation with factory-cut channels, insulation adhesive, glass fibre reinforcing mesh, non-combustible base coats, and a finish texture coat which can be selected from any one of the available Durex® Architectural Coatings. Quantum Select system is ULC rated as non-combustible cladding, meeting building code requirements for non-combustible construction.

  • CAN/ULC S716 compliant
  • CCMC listed (13103-R)
  • Continuous venting at floor lines and horizontal terminations, using pre-manufactured vented boards
  • Positive drainage (through a network of vertical and horizontal channels)
  • Continuous water resistive barrier
  • Simple interfacing with other pressure equalized
  • 2-hour fire rating in accordance with ULC W456
  • Economical
  • Aesthetic design flexibility
  • Continuous Insulation – CI Factor = 0.65 RSI/in (Type1 EPS)  - 0.70 RSI/in. (Type2 EPS)

Quantum Select is suitable for use over a wide range of structurally sound substrates and is recommended for use in buildings which require moisture managed cladding.
