The Best of Both Worlds

Adaptable to varying climatic conditions, Tyvek AirGuard Smart is said to be a membrane with a difference – developed by the experts in protecting structures against environmental damage while also improving thermal performance.

Wrapping the interior side of the envelope, Tyvek AirGuard Smart acts as an air and vapour control layer but has reportedly also been formulated to adapt to rising humidity conditions and so allows any trapped or unplanned, moisture to escape towards the inside of the building.

This variation is said to allow faster evacuation of built-in humidity in new construction elements (e.g. wet rafters). It reportedly also means avoiding humidity infiltration from living spaces into the building’s structure, thereby minimising the risk of expensive damage from damp and mould and so operating in the standard function of an AVCL.

With a variable water vapour resistance range of sd value 0.2m for a humid environment (1 MNs/g) to more than sd-value 35m for a dry environment (175 MNs/g), Tyvek AirGuard Smart is said to offer advantages from reduced drying out time for constructors to enhanced energy efficiency and comfort for the building owners.
