Quinn Therm QL Foil PIR Insulation is a high performance, fibre free insulated board, suitable dry-lining walls. It has a low emissivity composite foil facing on the inner side and plasterboard on the outer side.

The low emissivity foil facing increases the thermal resistance of an unvented cavity adjacent to the board improving the overall thermal performance of the element. It also minimises the board thickness required to achieve the design U-value.
