Moisture control is essential for protecting your home’s structure and maintaining good indoor air quality. A ground vapour barrier is a protective layer of polyethylene that prevents moisture from rising into your home’s insulation and living areas. Without it, excess moisture can lead to mould, rot, poor indoor air quality, and decreased insulation effectiveness. As per New Zealand’s Healthy Homes standards, a ground moisture barrier is required for all rental properties with an enclosed subfloor space, unless impractical to install, to prevent moisture from seeping up from the ground.  A properly installed ground vapour barrier helps maintain a dry, healthy home environment, and our installation team are expert in ensuring proper coverage and durability.
