What Is Vapour-Permeable Wall Wrap?

Vapour-permeable wall wraps like Vapawrap® are specially engineered membranes that provide a protective barrier behind external cladding. They allow internal moisture vapour to escape, while preventing wind-driven rain and external moisture from entering the building envelope.

Why Is a Breathable Wall Wrap Important?

Moisture trapped in wall cavities can lead to mould growth, structural decay, and poor thermal performance. By allowing walls to “breathe,” Vapawrap® helps reduce condensation build-up while maintaining energy efficiency – making it a vital component of modern Australian construction.

Where Can You Use Vapawrap®?

This wall wrap is ideal for use in:

• Timber and steel-framed homes

• Brick veneer and lightweight cladding systems

• Residential, commercial, and multi-storey buildings

• All Australian climate zones

Is Vapawrap® NCC Compliant?

Yes. Vapawrap® meets the National Construction Code (NCC) requirements for Class 4 vapour-permeable membranes. It also supports homes in achieving higher energy star ratings by managing internal moisture and protecting thermal insulation.

Benefits at a Glance:

• Allows water vapour to escape – helps walls dry out naturally

• Protects against external moisture – reduces weather ingress

• Improves air tightness and thermal performance

• Reduces the risk of condensation-related damage

• Australian-made and trusted by local builders
