ThermalFlex 4

Overview

Reflective insulation, vapour barrier and radiant barrier in one 4 mm sheet.

ThermalFlex™ 4 is a high performance reflective insulation, vapour barrier and radiant barrier. ThermalFlex™ 4 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™ 4 is also a fibre free insulation and non-allergenic.

ThermalFlex 4 carries no climate zone restriction, so it suits Perth roofs, walls and floors. It is the usual pick for sheds and workshops around Perth, where the anti-glare face matters as much as the R-value , the installer is looking up at it all day. At 1500 mm wide it covers ground quickly.

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.
• Reduces thermal bridging while minimising condensation in roof spaces as a water 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™ 4 is rated Extra Heavy Duty and is strong and durable, making it perfectly suited for use in roof, wall and floor applications. ThermalFlex™ 4 is ideal for use in residential homes, commercial buildings and domestic sheds, and will improve the energy efficiency and comfort of these buildings. ThermalFlex™ 4 also assists in reducing thermal bridging and minimising condensation along with providing high thermal performance as a radiant barrier. ThermalFlex™ 4 is easy to install and is manufactured at 1500 mm wide for maximising coverage and
