Accoya Windows in Radyr
Accoya is acetylated timber — dimensionally stable, rot-resistant and warranted for 50 years above ground. The best-performing paint substrate available.
Every accoya windows we make in Radyr starts the same way: a surveyor measures the actual opening, records the existing profiles and checks how the reveal sits. Nothing is ordered from a catalogue.
What is included
- Factory-finished in controlled conditions — three coats minimum, fully cured before delivery.
- End-grain sealed at every cut before assembly — the single detail that decides whether joinery rots.
- Micro-porous finishes that let the timber breathe rather than trapping moisture behind a hard film.
- Factory-finished in controlled conditions — three coats minimum, fully cured before delivery.
Choosing accoya windows for a property in Radyr is mostly a question of substrate and detail. Get the timber and the sections right and the finish looks after itself for decades.
We install across Cardiff with our own fitting teams and make good internally as part of the price. No sub-contracted surprises.

Questions
Do you take away the old windows?
Yes. Removal and responsible disposal are included, along with making good internally. We work one opening at a time so the property is never left open, and we clear the site each day.
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.
