Raglan, Monmouthshire
Double Glazed Timber Windows in Raglan
Argon-filled, low-e sealed units in hardwood frames — typically 1.2–1.4 W/m²K whole-window, comfortably Building Regs compliant.
Raglan has a housing stock that punishes off-the-shelf joinery — openings settle, reveals go out of square, and cills rarely sit level. Bespoke double glazed timber windows solve that properly.
What is included
- 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.
- 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.

Questions
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.
Do you repair windows or only replace them?
We repair wherever repair is the right answer. Rot is normally localised in a cill or the bottom of a stile, and splicing in new hardwood is typically a third of the cost of replacement. We will tell you honestly at survey which way the economics fall.
Can you match existing windows?
Yes. That is most of what we do. We record the existing sections at survey, reproduce the mouldings and sightlines, and match the finish. On listed buildings we will produce like-for-like profile drawings for the consent application.
