Project Overview: Preserving Character, Enhancing Efficiency
In the heart of Belper, Derbyshire, we were recently approached by a homeowner seeking to replace their tired timber windows with energy-efficient windows. The goal was clear: to upgrade to low-maintenance alternatives while preserving the property’s unique period charm. The ideal solution was a set of UPVC casement windows in Pebble Grey, designed to maintain the heritage aesthetic while providing the advantages of modern materials.
A key feature of this heritage window replacement was the encapsulation of the home’s original stained glass, allowing the client to safeguard an important part of the building’s history within the new double-glazed units.
Timber-Look UPVC casement Windows Case Study
Belper, part of the Derwent Valley Mills World Heritage Site, is known for its rich industrial history and traditional architecture. Our client’s home featured beautiful but ageing timber-framed windows, adorned with original stained glass details. While these heritage windows were full of character, they fell short in terms of insulation, security, and weatherproofing. To address these issues, our client sought energy-efficient windows that would enhance comfort and aesthetics. Their needs included: maintaining the home's original period charm, improving energy efficiency and reducing heat loss, preserving and protecting the existing stained glass, and opting for UPVC casement windows to reduce maintenance compared to traditional timber windows.
Our Solution: Pebble Grey Timber-Effect UPVC Windows
After a detailed consultation and site survey, we recommended UPVC casement windows with a smooth Pebble Grey finish that closely replicate traditional woodgrain textures and sightlines. These energy-efficient windows are 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 showcases a stunning example of how heritage window replacement can be achieved while preserving the unique character of older homes. The timber-look UPVC casement windows blend effortlessly with the property’s exterior, and the encapsulated stained glass maintains the story and detail of the original windows. The homeowner was thrilled—not only with the fresh new look but also with the noticeable improvement in warmth and sound insulation, thanks to the energy-efficient windows.
