Our External Wall Wrap is a waterproof and breathable membrane designed to protect exterior walls and insulation systems from wind-driven rain and moisture while allowing water vapor to escape.
Available in project-friendly rolls and customized specifications, it helps improve moisture management, weather protection and long-term wall system performance.
A building envelope needs to control moisture without trapping vapor inside the wall assembly. Our external wall wrap provides an effective protective layer behind exterior cladding, helping prevent wind-driven rain and external moisture from reaching the insulation and wall structure.
At the same time, its breathable structure allows water vapor to escape from the wall system, helping reduce the risk of moisture accumulation and condensation.
For projects using glass wool, mineral wool or other insulation materials, the membrane can be installed as part of a complete external wall insulation and weather protection system.
Helps protect insulation and wall structures from rain, wind-driven moisture and external water penetration.
Allows water vapor to pass through the membrane, supporting effective moisture management within the wall assembly.
Used together with glass wool or other insulation products, the membrane provides an additional weather-resistant layer for the insulation system.
Designed for installation behind siding, cladding, façade systems and other exterior wall finishes.
Available in different roll sizes, widths and performance specifications to meet the requirements of distributors, contractors and construction projects.
The external wall wrap can form an important part of a multilayer building envelope.
A typical wall structure may include:
The membrane is positioned on the exterior side of the insulation to provide weather protection while maintaining vapor permeability.
This makes it particularly suitable for wall systems where moisture control, insulation protection and long-term building envelope performance are important.
Our waterproof breathable membrane can be used in a wide range of construction applications:
Suitable behind finishes including:
When used together with insulation, an external wall wrap can provide an additional layer of protection for the building envelope.
Glass wool provides thermal and acoustic insulation, while the breathable membrane helps manage external moisture and weather exposure.
This combination can be particularly useful for projects where contractors need to source insulation and moisture-control materials from the same supplier.
We can also provide supporting insulation products, including glass wool and other building insulation materials, depending on project requirements.

External wall wrap is a protective membrane installed on the exterior side of a building wall, typically behind cladding or siding. It helps protect the wall assembly from external moisture while allowing water vapor to escape.
Yes. Waterproof breathable wall wraps are designed to resist external water penetration while maintaining vapor permeability. Exact waterproof and vapor performance depends on the membrane specification.
Yes. External wall wrap can be used as part of an exterior wall insulation system with glass wool. It provides an additional weather-protection layer around the building envelope.
It is generally installed on the exterior side of the wall assembly, behind external cladding or siding and in accordance with the requirements of the specific wall system.
Insulation primarily provides thermal and acoustic performance, while external wall wrap focuses on weather protection and moisture management. They perform different functions and can be used together in a complete building envelope.
Yes. Free samples are available for project evaluation. Please contact us with your application, required specification and estimated quantity.
Yes. Roll dimensions, packaging and other specifications can be discussed according to project requirements.
Whether you are sourcing materials for a new construction project, insulation project, building renovation or distribution business, our team can help you select the appropriate waterproof breathable membrane.
