This means that your home stays warmer in the winter and cooler in the summer, reducing your energy bills and carbon footprint.
  2. Better Sound Insulation: Double glazed sash windows are also effective at reducing noise pollution, making them ideal for homes located near busy streets or airports. The insulating properties of the windows help to dampen outside noise, providing a quieter and more peaceful indoor environment.
  3. Enhanced Security: Double glazed sash windows are more secure than traditional single glazed windows, as they are harder to break and come with locking mechanisms that make them more difficult to open from the outside. This makes them an excellent investment for homeowners concerned with their safety and security.
