Accoya Windows in Cardiff
Accoya is acetylated timber — dimensionally stable, rot-resistant and warranted for 50 years above ground. The best-performing paint substrate available.
Most accoya windows enquiries we take from Cardiff start with a photograph and a rough measurement. That is enough for an indicative figure — the survey firms it up.
Specified for Cardiff properties
- FSC-certified hardwood with documented chain of custody, available on request for planning submissions.
- Factory-finished in controlled conditions — three coats minimum, fully cured before delivery.
- Warm-edge spacer bars as standard, which cut the cold bridge at the glass edge and reduce condensation.
- End-grain sealed at every cut before assembly — the single detail that decides whether joinery rots.
- Compression seals rather than brush pile where the design allows, for a measurably tighter close.
If you have been quoted for accoya windows in Cardiff and the price looked suspiciously round, it was almost certainly a standard size with a filler piece. We do not work that way.
Everything is made to order, so the quotation stage matters. We would rather spend an extra hour on the survey than get a section wrong.

Questions
Which hardwood should I choose?
It depends on the finish. For painted work, Idigbo and Accoya are excellent — stable, even-grained and superb paint substrates. For a stained or oiled finish where the grain is meant to show, European oak and Sapele are the usual choices. We will recommend a species at survey based on your finish and exposure.
What is Accoya and is it worth the premium?
Accoya is timber that has been acetylated — chemically modified so it no longer absorbs water. It barely moves, does not rot, and carries a 50-year above-ground warranty. It is the single best paint substrate available. For exposed elevations and coastal sites the premium usually pays for itself.
How do the surveys and quotations work?
The guide price tool gives you an indicative range in a couple of minutes. If that range works, we book a free survey — measurements, profiles, exposure, access — and issue a fixed written quotation with a drawing. Nothing is manufactured until you have approved that drawing.
What sort of guarantee do you offer?
Ten years on the joinery and the manufacture, and the sealed units carry their own manufacturer's warranty. Accoya frames carry the 50-year above-ground timber warranty from the material supplier. All of it is confirmed in writing with the quotation.
Will the timber warp or stick?
Not if it is specified correctly. Sticking comes from moisture ingress into unsealed end grain, or from solid stock used where laminated sections were needed. Kiln-dried timber, sealed end grain, factory finishing and engineered sections on longer spans between them eliminate it.
