Resistant to extreme weather
Wintergarden glass room extensions stand up to even the most extreme weather conditions due to their robust durable frames and strong structural glass systems. They are compatible with either double or triple glazing to help insulate your home throughout the seasons while keeping out wind, rain, snow, dust and noise. We use a low-emissivity (Low-e) coating on the glass that prevents heat loss in the winter months while ensuring that your home remains cooler during hot summer days. Our Hawaii 80 has been certified by a major European governing body and tested against extreme snow and wind loads. Glass extensions are ultimately designed with weather resistance in mind, greatly increasing their lifespan and your safety with minimal need for maintenance.
Quick and hassle free installation time
A glass extension is amongst the simplest, least stressful ways to create additional room. Generally permitted development rights in England enable you to extend off of an existing building without applying for prior approval or planning permission from your local planning authority provided that the extension respects limits set according to the building regulations. This makes them hassle-free and quicker to install than other more traditional extensions as you don't have to go through complex paperwork or wait for a lengthy approval period; instead, installation can begin once your plans are ready. We would however recommend that you contact your local planning authorities to discuss your project and seek final clarity, particularly if you have already extended off of the original house, live in a conservation area, period property, or a place of natural beauty.
