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
