Slim Cavity Units for Porthmadog properties
What makes Slim Cavity Units work in Porthmadog is usually invisible once it is finished. Most of what we survey locally is slate-quarry terraces, Victorian resort stock and stone farmhouses, which is not built to any modern module. severe Irish Sea exposure with very high rainfall sets the pace of decay, and salt and rain combining to strip finishes and open glazing joints is how it shows up first. The value is in narrow cavities that perform while keeping the sightline historic, not in the timber bill.
The measuring is done by the people responsible for the fit, which concentrates the mind. Tell us the problem rather than the solution and we will advise on both.
Bear in mind for this area: Llandudno's Victorian frontages are protected as a coherent conservation set.
