Double glazed sash windows are a great choice for homeowners looking to enhance the energy efficiency of their properties whilst still maintaining the traditional aesthetics of their windows. Double glazed windows consist of two panes of glass with an air gap in between them, which helps to reduce heat loss and minimize outside noise. This, combined with their ability to trap heat inside your home, means that double glazed sash windows can help you save money on your energy bills whilst also creating a more comfortable and quiet living environment.
