Slim Cavity Units for Windsor properties

The Slim Cavity Units we make for Windsor is set out from a survey, not a size chart. The building stock is Thames-side villas, Victorian terraces and dense 1980s commercial fit-out stock, so we expect variation before we ever pick up a tape. river humidity and localised flood exposure is the local complication, and swelling and binding on ground-floor doors after flood or high water table events is what it eventually causes. What you are paying for is narrow cavities that perform while keeping the sightline historic.

We would rather spend an hour surveying than a week correcting. Send what you have, even if it is only a phone photo, and we will take it from there.

One thing that catches people out here: flood-zone properties benefit from raised thresholds and marine-grade fixings.
