Slim Cavity Units for Thorne properties
The Slim Cavity Units we make for Thorne is set out from a survey, not a size chart. The building stock is steel-era terraces, interwar council stock and stone village housing, so we expect variation before we ever pick up a tape. The weather does the rest: cold inland winters with prolonged damp here, and condensation-driven decay on single-glazed units in unheated rooms as the predictable result. Our focus on this is narrow cavities that perform while keeping the sightline historic.
Manufacture only starts once the survey figures are agreed with you in writing. Ask us for a figure and you will get one, with the lead time stated alongside it.
Worth knowing locally: large volumes of pre-1919 stock make sash repair the dominant enquiry.
