Yes, PUR can be used as insulation either for partial-fill cavities or fully-filling cavities. For many years PUR injected into cavity walls has been used, not only as a highly efficient insulant but also as a means of stabilising masonry cavity walls where wall ties have corroded or failed. It has also been used by many local authorities and housing associations for stabilising and insulating high rise buildings.

PUR/PIR insulation products meet a wide range of fire performance requirements as stipulated by both the Building Regulations and the insurance industry. For more information click here.

PUR and PIR are widely used in the insulation of pipes, ducts and vessels. Typically, depending on the formulation they can withstand high temperatures of up to 130°C.

PUR/PIR Insulation has been used successfully to insulate pipes and storage vessels in cryogenic applications at temperatures of –190°C. The insulation also has the flexibility to withstand temperature cycling from cryogenic temperatures to ambient.

Some products, such as roofboards, pipe insulation and insulated plasterboard are available through builder’s merchants. For more detailed information, contact please contact the manufacturers directly who will be able to put you in touch with your nearest stockist.
