Retrofit Double Glazing for Penryn properties
Nothing about Retrofit Double Glazing in Penryn is settled until someone has been on site. Because the area is mainly granite fishermen's cottages, slate-hung terraces and modern coastal builds, no two openings measure quite the same. Locally you are contending with the most severe salt and wind exposure in England, so accelerated coating failure and salt crystallisation damage at glazing lines is the fault we are called out to. Our focus on this is reworking the rebate so a sealed unit fits without bulking the section.
The site visit comes first, because assumptions made in an office get paid for on site. Send what you have, even if it is only a phone photo, and we will take it from there.
Bear in mind for this area: Cornish exposure grades mean specification should assume worst-case wind-driven rain.
