Xtroliner - Thermal PIR

The advanced PIR formula of Xtroliner PIR achieves high R-Value performance in a thin, slimline, rigid board profile and is approved for use in specific commercial building applications such as concrete soffits and concrete wall systems.


Xtratherm is a high performance building insulation that achieves significant thermal performance in a slimline, rigid board profile.

The product is made from an advanced thermoset polyisocyanurate (PIR) foam which is sandwiched between two layers of embossed aluminium foil facings. Its high thermal performance, slimline profile and high compressive strength, allows it to be efficiently designed into a building as a continuous thermal barrier across concrete soffits and concrete walls.
