IBS Quantum Select
Prefabricated Curtain Wall Panel System (Insulated Building Envelope)

IBS Quantum Select is not just a cladding – it is a unitized curtain wall system that integrates the performance of several wall components for providing the essential, environmental separation controls of heat / air / moisture / fire, strength, durability and aesthetics, all in one lightweight, energy efficient, cost-effective wall assembly. IBS is the new trend in energy efficient exterior curtain walls. It brings significant advancements to the conventional, architecturally limited, glass, stone or other material curtain walls through a water-managed, pressure-moderated and energy efficient wall system.

  • Pre-engineered Lightweight Panel Design
  • Speed of Construction
  • Pressure Moderated Rain Screen Design
  • Air/Water tight Building Envelope Design
  • Geometrically Defined Drainage Cavity (GDDC)
  • Superior Thermal Performance
  • 1 Hour Fire Rated System ULC W-489
  • 2-Hour Fire Rated System ULC W-485
  • Non-combustible base coats
  • Continuous Insulation - (CI) Factor = 0.65 RSI/in (Type1 EPS)   0.70 RSI/in (Type 2 EPS)

IBS Quantum Select provides the best wall solution for all types of construction, be it institutional, residential, commercial, industrial and/or temporary. IBS features a lightweight, wall assembly panel with a high strength to weight ration, eliminating the need for super structural elements such as beams and columns. IBS’s lightweight and flexibility make it an ideal solution for applications in high seismic/wind zones.
