ThermalFlex™ 8

Flexible Reflective Thermal Break Insulation

ThermalFlex™ 8 is a high performance reflective insulation, vapour barrier and radiant barrier.

ThermalFlex™ 8 consists of cross linked, closed cell foam core for improved thermal performance.
On each side of this foam core there are layers of reflective foil, one side with an antiglare and the inside
reflective face which provides a high quality finish, particularly for shed applications.
ThermalFlex™ 8 is also a fibre free insulation and non-allergenic.

ThermalFlex™ 8 is rated Extra Heavy Duty and is strong and durable, making it perfectly suited for use in
roof, wall and floor applications. ThermalFlex™ 8 is ideal for use in residential homes, commercial buildings
and domestic sheds, and will improve the energy efficiency and comfort of these buildings.

ThermalFlex™ 8 assists in reducing thermal bridging by meeting the NCC requirements for R0.2 thermal
break in steel frame construction, and minimises condensation while providing high thermal performance
as a radiant barrier.

ThermalFlex™ 8 is easy to install and is manufactured with a 150mm overlap piece for maximising
coverage while reducing wastage and providing cost savings. This overlap piece improves aesthetics and
minimises the need for taping joins.

Product Advantages

  • Meets R0.2 NCC thermal break requirements, suitable for steel and timber framed construction.

  • Insulation, vapour barrier and radiant barrier, reflecting up to 95% of radiant heat.

  • Extra Heavy Duty for strength, durability and maximum tear resistance.

  • Low Flammability to suit bushfire-prone areas.

  • Antiglare coating on the outer layer for installation safety and high quality foil finish on the inside.

Applications

Tile roof sarking, Metal roof sarking, Premium wall wrap.
