Accoya Windows in Suffolk
Accoya is acetylated timber — dimensionally stable, rot-resistant and warranted for 50 years above ground. The best-performing paint substrate available.
Timber moves. The craft in accoya windows is anticipating exactly how much, in Suffolk conditions, and detailing the joints and finish so that movement never becomes a problem.
Specified for Suffolk 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 accoya windows are made from kiln-dried hardwood, machined in the workshop and factory-finished before they ever reach a Suffolk site. Wet-brushing on site is where timber windows get a bad name.
Lead times for Ipswich are typically six to ten weeks from approved drawings, depending on timber and finish. Repairs are usually much quicker.

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.
Are hardwood windows secure?
Yes. Multi-point locking, laminated glass options and key-locking handles are all available, and a solid hardwood frame is considerably harder to attack than a hollow plastic one. We can specify to PAS 24 where a planning condition or insurer requires it.
