Description
ClimaBatts C4 Pallet 1500mm. Vapour Permeable Membrane
ClimaBatts C4 Pallet 1500mm Vapour Permeable Membrane provides reliable protection for Australian wall systems while allowing water vapour to escape from the building envelope. As a result, it helps manage moisture within wall cavities and supports the long-term performance of insulation and building materials.
Designed for Australian construction applications, ClimaBatts Wrap combines vapour permeability, water resistance and air-barrier performance in one practical building membrane. Additionally, the membrane has been tested to AS/NZS 4200.1, which covers pliable building membranes and underlays used throughout Australia and New Zealand.
ClimaBatts C4 Pallet 1500mm. Vapour Permeability
ClimaBatts Wrap achieves a Class 4 vapour permeance classification. Therefore, water vapour can move through the membrane rather than becoming trapped inside the wall system.
This vapour-open design helps reduce the risk of condensation developing within wall cavities. Furthermore, it allows the building envelope to dry more effectively when moisture enters the system during construction or normal building use.
Because Australian homes experience changing temperatures and humidity levels, effective moisture management remains an important part of modern building design. Consequently, ClimaBatts Wrap offers a practical solution for wall systems that require high vapour permeability.
Water and Air Barrier Protection
In addition to allowing vapour to escape, ClimaBatts Wrap helps protect the building from external moisture and uncontrolled air movement.
The membrane acts as a water barrier, helping reduce the risk of wind-driven rain entering the wall cavity. At the same time, it functions as an air barrier when installers correctly overlap, tape and seal the membrane.
As a result, the wrap can help improve the overall performance of the building envelope. Moreover, controlling unwanted air movement can support insulation efficiency by reducing draughts and limiting air leakage around the wall system.
Tested to AS/NZS 4200.1
ClimaBatts Class 4 Vapour Permeable Membrane has been tested to AS/NZS 4200.1. Therefore, builders, installers and specifiers can select the product with greater confidence for suitable residential and commercial wall applications.
However, correct installation remains essential. Installers should follow the ClimaBatts installation instructions, maintain the required overlaps and seal joins with compatible building tape. Additionally, all penetrations, openings and wall junctions should receive appropriate sealing to maintain the integrity of the membrane system.
Designed for Australian Building Applications
ClimaBatts Wrap suits a wide range of timber and steel-framed wall systems. It can form part of an external wall assembly behind suitable cladding systems and outside the insulation layer, subject to the project design and installation requirements.
Furthermore, the membrane works alongside ClimaBatts insulation products to create a more complete wall protection system. While the insulation helps control heat flow, the membrane assists with moisture management, water resistance and air control.
Protection Built In
ClimaBatts Class 4 1500mm Vapour Permeable Membrane delivers dependable protection without preventing walls from breathing. Therefore, it provides builders and installers with a practical membrane solution for modern Australian construction.
