Slim Cavity Units for Darwen properties
The Slim Cavity Units we make for Darwen is set out from a survey, not a size chart. Around here it is cotton-town terraces, Pennine stone cottages and Fylde coast resort stock, and that alone rules out anything bought by the pallet. The exposure here is high rainfall inland and severe wind exposure on the Fylde coast, which is exactly the condition that causes wind-driven rain penetration at meeting rails and sill joints. Our focus on this is narrow cavities that perform while keeping the sightline historic.
Every job is measured on site first, because drawn sizes and built sizes are seldom the same. We will price it properly in writing, and we will tell you if it is not worth doing.
A local consideration we always raise: coastal Fylde stock needs the same specification discipline as the South West.
