Double Glazed Timber Windows in County Down
Argon-filled, low-e sealed units in hardwood frames — typically 1.2–1.4 W/m²K whole-window, comfortably Building Regs compliant.
Timber moves. The craft in double glazed timber windows is anticipating exactly how much, in County Down conditions, and detailing the joints and finish so that movement never becomes a problem.
Specified for County Down properties
- Trickle ventilation designed into the head where Building Regulations require it, not drilled in afterwards.
- Kiln-dried to 12% moisture content before machining, so the sections stay true once they are installed.
- Engineered laminated sections on anything over 1.2m, which resist bowing far better than solid stock.
- Stainless or solid brass ironmongery, because plated steel fails first and takes the finish with it.
- Weathered cills with a proper drip groove, so water leaves the timber instead of tracking back under it.
Our double glazed timber windows are made from kiln-dried hardwood, machined in the workshop and factory-finished before they ever reach a County Down site. Wet-brushing on site is where timber windows get a bad name.
Lead times for Bangor are typically six to ten weeks from approved drawings, depending on timber and finish. Repairs are usually much quicker.

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.
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.
