Ametalin 1200 x 45 x 20mm ThermalCav Drainage Battens - 25 Pack

ThermalCav™ Drainage Battens is an innovative three layer, high-density polypropylene, self-adhesive, passive open air-flow strip. They are specifically designed to meet NCC 2022 R0.2 thermal break requirements for steel frame construction and create 20 mm ventilation and drainage plane while providing a hard base to fix and install to. ThermalCav™ Drainage Battens are ideal for use as a non-structural cavity spacer with vapour permeable and vapour barrier roof sarking and wall wraps in residential and commercial constructions where BCA R0.2 thermal separation, occasional water drainage, passive air-flow, energy efficiency and condensation control are paramount. In metal roofs, ThermalCav™ Drainage Battens helps to locate and keep the dew point to the underside of the roof cladding preventing condensation from forming on the underside of the pliable building membrane. ThermalCav™ Drainage Battens are provided with a high tack adhesive backing, so there is no need for temporary fixings. ThermalCav™ Drainage Battens can be installed in either vertical or horizontal orientation between steel framing, pliable building membranes and various cladding materials and roofing sheets. The 20 mm thickness allows for air gaps and reflective spaces for energy efficiency and ventilation requirements in NCC 2022 Vol 1, F8D5 and J4D3, and Housing Provisions 10.8.3 and 13.2.2. ThermalCav™ Drainage Battens is a three-layer high density polypropylene construction comprised of a formed inner PP core with 2 layers of premium high-density PP facing backed with self-adhesive backing.
