Advanced Tyvek® AirGuard® Smart offers a clever new way to control both airtightness and moisture
Adaptable to varying climatic conditions, Tyvek® AirGuard® Smart is a membrane that protects structures against environmental damage while also improving thermal performance.
Wrapping the interior side of the envelope, Tyvek® AirGuard® Smart acts as a highly efficient air and vapour control layer (which easily achieves below Passive house levels of airtightness) but has also been formulated to adapt to rising humidity conditions and so allow any trapped, or unplanned, moisture to escape towards the inside of the building.
This clever variation enables faster evacuation of built-in humidity in new construction elements (e.g. wet rafters). It also means avoiding humidity infiltration from living spaces into the building’s structure, minimising the risk of expensive damage from damp and mould.
Tyvek® AirGuard® Smart can be fitted to both flat and pitched roof constructions, with a high resistance underlay. It comes with clear and detailed installation guidelines and the technical back-up of the Tyvek® Building Knowledge Centre
