50mm Unilin ThinR XT/CW Partial Fill Cavity Wall Insulation Board is a PIR insulation board with a high thermal performance whilst maintaining a residual cavity in the external walls. This board achieves high standards of insulation with a certified thermal conductivity of 0.022W/mK with the optional benefit of fully engineered jointing and pre-formed corners to ensure insulation continuity and avoid thermal bridging. The closed cell structure and gas tight facings provides excellent thermal performance and moisture resistance. The residual cavity is the most effective method of preventing rain penetrating a wall from the outside.

Note: This product is formerly known as 50mm Xtratherm Thin-R XT/CW Partial Fill Cavity Insulation

  • partial fill cavity wall insulation

CHARACTERISTICS

  • Low emissivity foil facings,
