Slim Cavity Units for Merthyr Tydfil properties
Slim Cavity Units is one of those jobs in Merthyr Tydfil where the survey decides everything. You are mostly dealing with valleys terraces, Victorian maritime villas and civic Portland stone frontages around here, so openings vary more than people expect. With very high rainfall with strong Atlantic and Bristol Channel exposure in the mix, prolonged wetting decay and finish failure on valley-facing elevations is a question of when rather than whether. In practice that means narrow cavities that perform while keeping the sightline historic.
Nothing goes into manufacture until a surveyor has checked each opening on site. Get in touch and we will be straight with you about cost and timescale.
A detail specific to this area: valleys terraces share a repeating bay and sash format that suits batch manufacture.
