ThermalFlex 8

Overview

The thicker core, for where a thermal break is required.

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.

The reason to choose 8 over 4 is the thermal break. Steel framing conducts heat straight through the building envelope, and the NCC asks for a break at the frame , this is the product that answers it, in a single layer that also acts as sarking.

Product advantages

• Insulation, vapour barrier and radiant barrier, reflecting up to 95% of radiant heat.
• Extra Heavy Duty for strength, durability and maximum tear resistance.
• Meets R0.2 NCC thermal break requirements, suitable for steel and timber framed construction.
• Minimises condensation in roof spaces as a water and vapour barrier.
• Achieves low flammability results when tested to AS/NZS 1530.2.
• Suitable for bushfire-prone areas and use in construction requirements with BALs of LOW – FZ.
• Antiglare coating on the outer layer for installation safety and high quality foil finish on the inside.

Applications

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 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.
