Polyurethane board, more commonly referred to as PIR or simply PU board, is a highly efficient rigid insulation material. Widely used within the construction and automotive industries, it is formed through a specific chemical reaction; the creation of a closed-cell structure being the defining feature. A near perfect combination of various properties makes this material the preferred choice for many professionals.
Key Advantages of Polyurethane Board
Exceptional Thermal Insulation
One of the lowest thermal conductivity values common insulation materials can achieve is possessed by polyurethane board. The aforementioned closed-cell structure traps inert gases, effectively providing near complete resistance to all forms of heat flow. Consistent temperatures inside buildings or vehicles are maintained, with direct associated reductions in both heating and cooling costs.
High Strength-to-Weight Ratio
Lightweight as the board may be, remarkable structural rigidity and some level of compressive strength are exhibited. Easy handling and installation (physical or otherwise) do not compromise on durability; roofing, wall panels and to a point vehicle bodywork, all benefit from this characteristic.
Moisture and Water Resistance
Again due to the closed-cell nature, moisture absorption is inherently limited. Fibrous insulation fails in damp conditions, sagging, rotting and losing said insulating properties; polyurethane board will not. Long term performance and near constant protection against mold are both ensured.
Durability and Longevity
Aging, various weathering factors and near infinite chemical exposure are all well within the board’s resistance – structural integrity and all round insulating performance can be maintained for many years.
Common Applications
Building/Construction
Insulated roof and wall panels, facade systems.
Automotive
Commercial vehicle bodies (reefers being a prime example).
Cold Storage/Warehousing
Cold rooms and/or all round temperature controlled spaces.
Conclusion
Polyurethane board is and will always be to me, a superior insulation material. Energy efficiency and all that it enables, is a part of its true value.
