VapourFlex VPM

Overview

Class 4 vapour permeable wall wrap for Perth walls.

VapourFlex® VPM is a flexible and lightweight wall wrap that is highly vapour permeable and yet is also highly resistant to water transfer. Manufactured with two layers of resilient non-woven fabric on each side and a highly permeable membrane in the centre, VapourFlex® VPM is perfectly suited for both commercial and residential buildings that require a second layer of protection against moisture, wind and dust while

Perth sits in ABCB Climate Zone 5, where a wall wants to breathe outward. VPM is Class 4 vapour permeable and a water barrier: water vapour diffuses out through the non-woven core while liquid water cannot get in. Rated for up to 90 days of UV exposure, so it tolerates a slow build.

Product advantages

• Suitable for use behind all cladding types and wall systems such as fibre cement sheets,
• weather board, timber and brick veneer construction.
• Class 4 Vapour Permeable Membrane and a Water Barrier in compliance with AS/NZS 4200.1.
• Suitable for use in Climate Zones 2-8 in both commercial and residential applications.
• 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.
• Up to 90 days UV resistance and extremely durable.

Applications

VapourFlex® VPM is designed for use in walls and gable applications in Australian Climate Zones 2-8, and particularly where a vapour permeable membrane is required. VapourFlex® VPM is suitable behind all wall types and systems. These include brick veneer and all lightweight clad walls, such as fibre cement, weather board and timber, where manufacturers may require the use of vapour permeable membranes. VapourFlex® VPM also protects the building frame and internals from the elements prior to the external cladding being installed, allowing internal works to commence earlier.
