At this charming period property in Bishop’s Stortford, Herts, we successfully completed the retrofitting of original wooden sash windows with vacuum double glazing, combining modern insulation technology with historic aesthetics. The project involved reglazing the existing single-glazed sashes with high-performance vacuum double glazing units while refurbishing and painting the timber window frames.
Despite the significant height of the house, our team managed the work efficiently without the use of scaffolding, completing the entire project in under two weeks. The result is a seamless blend of enhanced energy efficiency and restored architectural elegance, preserving the character of the property while delivering significant improvements in thermal performance.
The primary objective was to improve the energy efficiency of the house by retrofitting the original sash windows with vacuum double glazing.
These windows, typical of period properties, were single-glazed and allowed for significant heat loss.
The new vacuum double glazing units significantly reduce heat transfer and enhance insulation, achieving a much lower U-value compared to single glazing.
As part of the process, the original timber frames were carefully restored.
The sashes were removed, reglazed with ultra-slim vacuum double glazing that fits seamlessly into the historic frames. This ensures that the new glazing does not disrupt the period aesthetic of the property.
Furthermore, the frames were refurbished and repainted to restore their former glory while adding protection against future weathering.
Draught-proofing was incorporated into the refurbishment to further reduce energy loss and eliminate common problems such as rattling and drafts.
This enhancement not only improves comfort but also adds to the energy efficiency of the home, offering greater temperature control during both summer and winter months.
The newly installed Landvac glazing units have vastly improved the energy efficiency of the home, reducing heat loss and making the house more comfortable for its occupants. Additionally, the integration of draught-proofing ensures that the refurbished sash windows no longer allow cold air to enter the property, offering better thermal control and helping the homeowners save on heating costs.
The homeowners expressed their satisfaction with the results, highlighting the seamless integration of modern energy-saving technology with the preservation of the home’s historical character.
