Slim Cavity Units for Truro properties

We take a fair volume of Slim Cavity Units work across Truro, and almost none of it repeats. The housing here is largely granite fishermen's cottages, slate-hung terraces and modern coastal builds, and that shapes what will actually fit. Because of the most severe salt and wind exposure in England, we see accelerated coating failure and salt crystallisation damage at glazing lines more often here than in most of the country. In practice that means narrow cavities that perform while keeping the sightline historic.

We would rather spend an hour surveying than a week correcting. A quick call or a photograph of the opening is usually enough to get you a price.

Something particular to this area: Cornish exposure grades mean specification should assume worst-case wind-driven rain.
