Make your conservatory feel usable again
At Sheffield Double Glazing Co, we install warm roofs that turn your conservatory from a room you avoid into a space you can enjoy every day. We fit thermal-tiled roof systems across Sheffield that help keep heat in during winter and reduce summer overheating. That matters when your old glass or polycarbonate roof leaves you with glare on the telly, too much noise in the rain, or a room that swings from freezing to stuffy.
Our insulated tiled systems are made to measure, so they suit replacement conservatory roof projects as well as new glazed extensions. Because the tiles are ultra lightweight GRP, they can work with existing conservatory frames without piling on unnecessary weight. In most cases, we can complete the installation in 2 to 3 days, which means less disruption and a faster route to a room you'll actually use.
Designed to work with the conservatory you already have
A good thermal roof needs more than decent tiles, and that's why we use a fully insulated system with GRP rafters and a reinforced ring beam to keep the structure light and strong. Our low U-value of 0.15 helps create steadier indoor temperatures, so your extension feels more like part of your house and less like a seasonal extra.
Style matters too, and you can choose slate-style or standard tile finishes in a range of colours to match the look of your home or even complement your new composite doors. We can fit these systems on Edwardian, Victorian, P-shaped and gable-ended conservatories, along with many other layouts. Inside, we can adapt the finish to suit the room you want to create, whether that's a bright dining area, a calmer home office or a family space with less echo.
