Description
Ametalin ThermalCav™ Drainage Battens are innovative, three-layer, high-density polypropylene, self-adhesive, passive open air-flow strips. They are specifically designed to meet NCC 2022 R0.2 thermal break requirements for steel frame construction and create a 20 mm ventilation and drainage plane while providing a hard base for fixing and installation.
Ideal for use as non-structural cavity spacers with vapour permeable and vapour barrier roof sarking and wall wraps in residential and commercial constructions, these battens address BCA R0.2 thermal separation, occasional water drainage, passive air-flow, energy efficiency, and condensation control. In metal roofs, they help locate and maintain the dew point on the underside of the roof cladding, preventing condensation from forming on the underside of the pliable building membrane.
Equipped with a high-tack adhesive backing, Ametalin ThermalCav™ Drainage Battens eliminate the need for temporary fixings and can be installed vertically or horizontally between steel framing, pliable building membranes, and various cladding materials and roofing sheets. The 20 mm thickness allows for air gaps and reflective spaces, meeting energy efficiency and ventilation requirements in NCC 2022 Vol 1, F8D5 and J4D3, and Housing Provisions 10.8.3 and 13.2.2.
