Applications

Limitations

Product is not for use in roofing applications.

Product is not reflective.

Product is not recommended for wall applications in ABCB Climate Zone 1.

In direct fix cladding applications where the cladding reduces the drainage and drying capability of the product, an external drainage cavity is recommended using Ametalin Cavity Drainage Battens™ (10 mm) or ThermalCav™ Drainage Battens (20mm). Non-absorbent claddings such as steel, adequate drainage must be provided.

VapourTech® Wall should not be used in direct contact with fresh LOSP or organic solvents and should be given at least 7 days for the chemicals to flash off before direct fixing. Oil-based treated timbers should be separated from this product or alternative pliable building membranes investigated and specified such as Ametalin CeaseFire®.

Blackbutt, Blackwood, Ironbark, Jarrah, Merbau, and Spotted Gum timber cladding among others, known for their high tannin content, natural faults and borer holes, have tendencies to leach and leak in conditions of very high humidity and /or prolonged water exposure. All direct to stud applications of the above treated timbers should be avoided therefore it is recommended that VapourTech® Wall should be separated by the incorporation of an external drainage cavity. and cladding placed on non-reactive battens to the external side of VapourTech® Wall. For specific timber and timber construction compatibility inquiries, kindly contact the Ametalin Technical team.
