In the quest for a more energy-efficient and quiet home, many homeowners are turning to secondary glazing

Unlike double glazing, which requires the replacement of existing windows, secondary glazing involves adding an extra layer of glass or acrylic inside your current windows. This method is particularly beneficial in heritage properties where preserving original frames is essential, but it's also useful in properties where double or triple glazing is not an option.
