Building wraps/membranes are useful for so many reasons. Building performance is only a part of the picture, when looking at control layers, with building envelope loads. When considering where the building is and what environment a building is maintaining, it becomes clear what we should be expecting from our wall systems.
- Protecting the building during construction from weather conditions. over the duration of the build.
- Controlling moisture in wall cavities is critical with a vapour barrier.
- Improving insulation performance
- Stopping moisture from outside getting into your wall system, and stopping moisture from inside getting in a wall system, with a vapour barrier on other circumstances.
