Do you have a period property with original sash windows or casement windows that need restoring or upgrading? At Sash Window Experts, we recognise that double-glazed windows are now an essential feature of the modern home, with many proven benefits over single-glazed period windows.
We work with the latest advances in technology in the double-glazing industry to provide beautiful double-glazed sash windows in hard or soft wood, that have the following advantages.
Benefits of double-glazed period windows
Greater energy efficiency
Recent figures have shown that somewhere in the region of 50-70% of heat in the home is lost through having single-glazed windows. Installing double-glazed windows achieves better thermal performance by trapping a layer of air between two glass panels. It is one of the most efficient ways to improve the energy efficiency of your home.
Lower energy costs
Changing your windows from single-glazed to double-glazed sash windows will help you keep more of the heat in your home. This means you can keep the central heating thermostat turned down in order to reach the same internal temperature, saving on energy consumption and utility bills.
Better sound insulation
Changing your windows from single-glazed to double-glazed sash windows will help you keep more of the heat in your home. This means you can keep the central heating thermostat turned down in order to reach the same internal temperature, saving on energy consumption and utility bills.
More home security
Double glazing is also an effective method to provide a greater level of home security, and the peace of mind that comes from knowing your family is safe at all times. Particularly on the ground floor, modern construction methods and double-glazed window panes will make it much harder for any intruder to gain access.
Easier maintenance
Timber-framed, double-glazed sash windows have a timeless appeal that perfectly complements older properties and listed buildings. Routine cleaning with warm soapy water is all it takes to preserve your windows. Carry out periodic checks for moisture ingress, and wear and tear and apply a fresh coat of paint where necessary.
Can you retrofit double glazing sash windows?
Installing double glazed sash windows to replace original single glazing may not always be possible without planning permission, for instance in period properties in Conservation Areas or listed buildings. One way to get around this is to leave the original windows in situ and retrofit double glazing into to the existing sash windows.
Retrofitting double glazing to timber windows is done by removing the existing single panes and replacing them with new slim-line low-profile heritage double glazing. These can be retrofitted into narrow rebates of original timber sash windows. Heritage double glazing uses slimline, low-profile double glazing units with exceptional thermal insulation that will improve their energy efficiency to match the performance of a modern A-rated window.
This alternative type of double glazing installation ensures that important original architectural characteristics of historic properties are preserved while providing the convenience of energy efficiency.
