ThermalFlex™ 4
Flexible Reflective Insulation
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 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
faster installation.
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.
-
Low Flammability to suit bushfire-prone areas.
- Reduces thermal bridging while minimising condensation in roof spaces as a water barrier.
- 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.
Blank one so all stay closed
