Window frames before restoration and reglazing
The cottage windows in this restoration and reglazing project were weathered and deteriorated, needing significant attention.
The wooden frames, originally painted a dark color, had substantial chipping and flaking, especially around the edges, exposing the underlying wood.
Dark colors on wooden frames can make them more vulnerable to sun damage. The darker paint absorbs more heat, causing the wood to expand and contract more than it would with lighter colors.
Over time, this can lead to accelerated wear, including cracking, warping, and peeling, as the wood struggles to withstand the temperature fluctuations.
Double glazing and restoration process
The existing single-glazed panes are replaced with double-glazed units.
The new units are securely sealed into the sashes with glazing putty, preserving the traditional appearance. The vacuum double glazing doesn’t have spacer bars, making it a visually suitable option for listed properties.
Enhanced thermal efficiency and durability of original windows and frames
As the final result of the restoration project, the new vacuum insulated glazing, which is as efficient as high-quality triple glazing, has made the original windows as efficient as possible. They would most likely achieve an A+ energy rating if tested, as the U-value of the glazing units is below 0.7.
