MEI’s published reference describes rigid polyurethane foam as a predominantly closed-cell insulation material used against temperature extremes. Its properties depend on the exact grade and test method.
Properties to review
- Thermal conductivity and density
- Water absorption and water-vapour transmission
- Closed-cell content and dimensional stability
- Compressive strength, friability and fire classification
The live reference provides example values and test methods for these categories. Obtain current certified values for the exact product, thickness and application before specification.
Confirm the current specification
Published charts and examples are useful starting points. Final material selection must follow current approved technical documentation and the project design.
