Easy to install

BEWI is manufactured from expanded polystyrene (EPS) which is lightweight and easy to handle.

It is easily installed and there is generally no need for specialized trades or equipment, therefore disruption to the building occupants is minimal.

Environment

EPS has been awarded an A+ rating by the BRE’s Green Guide to specification.

Permanent

BEWI is rot-proof and durable and will remain effective for the life of the building;

recommended fixing methods will retain the boards permanently in position.

It also has the added advantage of being flood-proof.

Fire

Any necessary fire performance should be provided by the facing material and the system design.

Water vapour transmission

BEWI offers significant resistance to the passage of water vapour, but should not be regarded as a vapour-control layer.

Condensation calculations covering typical environmental conditions show that the dew point of an external-wall insulation

system will occur on the external face of the insulation.

This is the ideal situation.
