Slim Cavity Units for Penzance properties
Slim Cavity Units in Penzance is rarely a catalogue job. Local property is overwhelmingly granite fishermen's cottages, slate-hung terraces and modern coastal builds, which is why we never quote from a catalogue. The weather does the rest: the most severe salt and wind exposure in England here, and accelerated coating failure and salt crystallisation damage at glazing lines as the predictable result. The detail we will not compromise on is narrow cavities that perform while keeping the sightline historic.
The site visit comes first, because assumptions made in an office get paid for on site. Tell us the problem rather than the solution and we will advise on both.
Bear in mind for this area: Cornish exposure grades mean specification should assume worst-case wind-driven rain.
