- Custom lengths, thicknesses and compressive strengths are available upon request. Please contact your local Halo dealer or Halo representative.
- Typically, XPS and ISO insulation products are not guaranteed to maintain their published R-values over time. Halo meets or exceeds most XPS guaranteed R-Values (check the guaranteed R-value with your XPS supplier).
- Listed compression values are minimum requirements conforming to ASTM C578, and CAN/ULC S701. Halo Products meet or exceed the requirements of ASTM C578, “Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation”, and CAN/ULC S701, “Expanded Polystyrene Insulation Board and Pipe Covering”
