70mm Xtratherm FR/BGM is an insulation board suitable for partially or fully bonded, torched-on, built-up bituminous felt systems. Product is faced with a polypropylene fleece finished bitumen/glass fibre working surface and a mineral glass facing to the underside.

Xtratherm FR-BGM is BBA certified to the high performance flat roof insulation standards providing guaranteed quality solution to flat roof specification.

Boards are manufactured with CFC/HCFC free blowing agent that has zero ozone depletion potential (ODP) and a low global warming potential (GWP).

Application:

70mm Xtratherm FR-BGM provides effective thermal insulation in:

  • partially bonded, torched-on, built-up bituminous based water proofing systems typically including a BS 747 type 3G perforated base layer or proprietary system
  • fully bonded systems (Fleece side upper most). Guidance in regard to moisture and condensation should be in accordance with BS 8217: 2005 (Reinforced bitumen membranes for roofing)

Xtratherm FR/BGM is suitable for use on roof decks that are subject to limited maintenance foot traffic.

The construction should be protected from rain penetration during breaks in the process. With fully bonded applications additional care is required to ensure that the construction remains free from moisture. Failure to protect will result in blistering of the waterproof layer.

Advantages of 70mm Xtratherm FR-BGM Flat Roof Insulation Board:

  • High thermal performance rigid insulation (PIR)
  • Compatible with most bituminous based roofing systems
  • Compatible with most green roof systems
  • Non-deleterious material
  • Zero ozone depletion potential (ODP) and low global warming potential (GWP)
  • Manufactured without the use of CFC’s/HCFC’s
  • Suitable for new build and refurbishment projects
