Making period and listed homes energy-efficient is achievable
No one should have to endure a draughty home. Restoring and upgrading original windows will not only make a house more energy-efficient and comfortable; it also retains its historic character for years to come.
Making period and listed homes energy-efficient, and still characterful, is achievable! Original sash windows can be upgraded to reduce heat loss without full replacement.Mitchell & Dickinsonprioritises restoration over replacement, offering sustainable solutions that preserve a building's charm. Windows can be restored by removing rotten sections and splicing in sustainably grown oak, retaining much of the original timber.
The discreetCosyGlazing secondary glazing system is designed for period homes and allows for the opening of both sashes. This reduces heat loss by around 70%, offering energy efficiency comparable to double glazing; but with a much longer lifespan and without adding to landfill.
Another option is retrofitting vacuum glazing to the original windows, provided the frames have sufficient depth. Vacuum glazing achieves the same U-values as triple glazing but is slimmer, making it ideal for period properties.
In terms of ballpark costs, integrated sliding sash CosyGlazing, which includes the complete re-engineering of sash windows, with concealed brush draught-proofing, perfectly balanced weights, new pulleys and sash cords, starts from £2,200, increasing for customised features such as arched windows. Retrofitting vacuum glazing into Victorian sashes typically costs between £2,500 and £3,500.
While restoration can initially seem costly, it's a worthwhile investment. Modern double-glazed units often need replacing within 5-10 years, but restored timber windows with secondary or vacuum glazing can last for generations. Regular maintenance, such as repainting every 3-5 years, is straightforward and cost-effective. Even if your budget is tight, you could approach the work in phases, restoring one or two windows at a time to spread costs.
