Triple Glazed Timber Windows in Derby
Triple glazing in hardwood needs a deeper frame section to carry the weight. Done right it drops whole-window U-values to around 0.8 W/m²K.
The case for triple glazed timber windows in Derby is straightforward — hardwood outlasts the alternatives, can be repaired rather than replaced, and holds the character of the building.
What is included
- Compression seals rather than brush pile where the design allows, for a measurably tighter close.
- FSC-certified hardwood with documented chain of custody, available on request for planning submissions.
- Warm-edge spacer bars as standard, which cut the cold bridge at the glass edge and reduce condensation.
- Compression seals rather than brush pile where the design allows, for a measurably tighter close.
A well-made triple glazing in Derby should open with one hand, seal without slamming and need nothing more than a wash and an occasional inspection. That is the standard we work to.
We install across Derbyshire with our own fitting teams and make good internally as part of the price. No sub-contracted surprises.

Questions
How much disruption should I expect?
Less than most people fear. A straightforward replacement is one opening at a time, typically two to four windows a day. Scaffolding is only needed on higher elevations. We protect floors and furniture and leave the site clean each evening.
How long do hardwood windows actually last?
Properly specified and maintained hardwood joinery has a realistic service life of 60 years or more. The timber is rarely what fails — it is the finish and the seals, and both are renewable. That is the fundamental advantage over uPVC, where a failed unit or a distorted frame means the whole window goes.
Are timber windows warm enough for Building Regulations?
Yes, comfortably. Timber is a natural insulator with far lower conductivity than aluminium or steel. A standard hardwood double-glazed window achieves around 1.2–1.4 W/m²K whole-window, against a 1.4 requirement for replacements. Triple glazing in a deeper section will reach roughly 0.8.
Can I have double glazing in a conservation area?
Usually, yes — using slim-profile sealed units as narrow as 11mm, which fit within traditional glazing bar sections without fattening them. Conservation officers vary, so we specify from the outset to whatever the local authority has stated and provide section drawings for the application.
