Detailing is agreed before ordering, opening by opening. It is the difference between an EWI scheme that lasts thirty years and one that develops damp in three.

On blocks of flats the fire performance of the whole external wall build-up is designed and checked before work starts, and the rules tighten with building height. We install to the design and do not substitute materials.
