Xtratherm Thin-R Pitched Roof PIR Insulation Board

Xtratherm Thin-R Pitched Roof PIR Insulation Board. The leading loft insulation board. This is also known as Xtratherm XT/PR insulation board

  • Effective insulation of roof area
  • Board size: 2400 X 1200mm
  • Reduces thermal bridging
  • Avoids intrusion into living area
  • Price per sheet


Using Xtratherm on sloped roof areas can provide the most efficient U-values with minimal intrusion into valuable living space. Warm Roof construction is a particularly effective way of insulating complex roofs. Insulating above and between the roof timbers ensures that the structure is kept at, or near the internal environmental conditions, reducing thermal stress and condensation risk.

Placing Xtratherm Thin-R between and/or below the rafter creates a Ventilated Roof. A continuous 50mm ventilation space is required between the insulation and the roof tile underlay to allow any moisture to be vented out of the construction. The high performance to thickness ratio of Xtratherm gives the maximum insulation values with minimal intrusion into the living area below.

The Hybrid Roof follows the same construction as the Vented Roof - but an approved Vapour Permeable underlay is used above the rafter allowing the 50mm ventilation space to be dispensed with. A 25mm unvented void should be maintained.
