The Challenge
Belper, part of the Derwent Valley Mills World Heritage Site, is known for its rich industrial history and traditional architecture. Our client’s home had beautiful but ageing timber-framed windows with original stained glass details. These windows, though full of character, were no longer providing adequate insulation, security, or weatherproofing.
Their needs included:
- Maintaining the original period charm of the home
- Improving energy efficiency and reducing heat loss
- Preserving and protecting the existing stained glass
- Reducing maintenance compared to traditional timber windows
Our Solution: Pebble Grey Timber-Effect UPVC Windows
After a detailed consultation and site survey, we recommended timber-look UPVC casement windows with a smooth Pebble Grey finish. These windows closely replicate traditional woodgrain textures and sightlines, making them ideal for heritage window replacement projects in sensitive areas like Belper.
Most importantly, we encapsulated the customer’s original stained glass within the new double-glazed units — sealing the leaded glass inside modern insulating panels. This not only preserved the authentic design but also protected it from further weathering and damage.
Key Features of the Installation:
- Pebble Grey UPVC casement windows – subtle, neutral tone ideal for traditional exteriors
- Flush timber-style profiles – giving the appearance of painted wood without the upkeep
- Stained glass encapsulation – original decorative glass sealed between double glazing
- Energy-efficient glazing – improved warmth, reduced drafts, and lower energy bills
- Secure locking systems – for modern peace of mind
The Result: A Seamless Blend of Heritage and Modern Comfort
The finished result is a stunning example of how heritage window replacement can be done without losing the character that makes older homes so special. The timber-look UPVC frames blend effortlessly with the property’s exterior, while the encapsulated stained glass retains the story and detail of the original windows.
The homeowner was delighted — not just with the fresh new look, but also with the noticeable improvement in warmth and sound insulation.
