What is Xtratherm Thin-R?

Xtratherm Thin-R XT/UF is a high-performance floor insulation product. Key characteristics include:

  • Composition: Made with a rigid Polyisocyanurate (PIR) core, it's sandwiched between low emissivity foil facings.
  • Manufacturing Standards: Manufactured to EN 13165 standards by Xtratherm.
  • Green Credentials: Achieves an A+ rating under the BRE Green Guide.
  • Technical Specifications:
    • Thermal Conductivity: 0.022 W/mK
    • Compressive Strength: >140 kPa
    • Reaction to Fire: NPD

Xtratherm Thin-R Applications

1. Ground Supported Floors:

  • Lay and level the hardcore.
  • Sand blind base for a levelled surface.
  • Apply a damp proof membrane (DPM) over the base.
  • Install the XT/UF across the DPM in staggered joint patterns.
  • Apply Xtratherm Perimeter Strips (XT/STR) for robust detailing.
  • Overlay with a thin polythene sheet as a separating layer.
  • If underfloor heating is needed, lay pipes according to guidelines.
  • Complete with a concrete slab or screed as required.

2. Suspended Timber Floors

  • Set up joists ensuring adequate ventilation.
  • Cut XT/UF to fit between the joists.
  • Mechanically fasten treated timber battens to the joists.
  • Insert XT/UF between joists and seal gaps using expanding foam.
  • Overlay with floorboards.
