Xtratherm ThinR XT/CW Partial Fill Cavity Wall Insulation is the best solution when designers or regulations demand additional thermal insulation in external masonry walls, without a substantial increase in the width of the cavity. Xtratherm Thin-R boards achieve high standards of insulation whilst maintaining a residual cavity to prevent moisture penetration, without a substantial increase in the width of the cavity and of the overall wall thickness.

APPLICATION

CHARACTERISTICS

  • The board comprises a CFC/HCFC free rigid Polyisocyanurate (PIR) core between low emissivity foil facings.
  • Square Edge
  • Clear cavity maintained
  • No exposure restrictions
  • Extra thermal performance Refer to NBS clause F30 155, F30 12

The Low emissivity foil facing on Xtratherm boards improve the thermal performance of the wall. The residual cavity is the most effective method of preventing rain penetrating a wall from the outside. The wall insulation shall be installed in accordance with instructions issued by Xtratherm.
