Slim Cavity Units for Barrow-in-Furness properties

Slim Cavity Units is one of those jobs in Barrow-in-Furness where the survey decides everything. Most of what we survey locally is Lakeland slate cottages, Georgian Carlisle stock and coastal industrial terraces, which is not built to any modern module. Then there is the highest rainfall in England with severe upland exposure, which reliably produces sustained saturation decay and finish failure within short recoating cycles given enough seasons. What we concentrate on is narrow cavities that perform while keeping the sightline historic.

The survey happens before manufacture, which is why our units fit without packing or trimming. A quick call or a photograph of the opening is usually enough to get you a price.

A local consideration we always raise: Lake District National Park controls window style closely across the central valleys.
