Extraglaze is both a supplier and installer of specialist secondary glazing services, with a rapidly expanding network of trained fitters. Our customers include home owners, offices, schools, even holiday resorts with single glazed windows. We frequently install our secondary glazing in listed buildings and conservation areas, as well as church conversions, often with arched and stone framed windows. Extraglaze will even turn double glazing into triple glazing, and stop condensation. If you live in a noisy city or town centre, especially with draughty, badly sealed sash windows, it will bring you the sound insulation you never imagined possible, even as you watch the traffic pass by! We insulate sash windows and insulate casement windows. All our panels are made to measure. We make special shapes, arches and out-of-square panels, even bowed (3 dimensional) panels for windows that follow curved facades. We supply and fit magnetic secondary glazing for sash windows and casement windows, and of course stained glass windows. If you require energy saving windows then insulating sash windows is a great alternative to window replacement or window renovation. The low cost of secondary double glazing is affordable compared to replacement sash windows & replacement casement windows. Extraglaze offers window thermal insulation and sound insulation for existing windows including stained glass windows. Both double glazed sash windows and triple glazed sash windows are possible. Extraglaze can turn draughty old windows into energy efficient windows.
