Slim Cavity Units for Lancaster properties
The Slim Cavity Units we make for Lancaster is set out from a survey, not a size chart. Because the area is mainly cotton-town terraces, Pennine stone cottages and Fylde coast resort stock, no two openings measure quite the same. With high rainfall inland and severe wind exposure on the Fylde coast in the mix, wind-driven rain penetration at meeting rails and sill joints is a question of when rather than whether. Our focus on this is narrow cavities that perform while keeping the sightline historic.
We would rather spend an hour surveying than a week correcting. Ask us for a figure and you will get one, with the lead time stated alongside it.
One local point to factor in: coastal Fylde stock needs the same specification discipline as the South West.
