Triple Glazed Timber Windows in St Austell
Triple glazing in hardwood needs a deeper frame section to carry the weight. Done right it drops whole-window U-values to around 0.8 W/m²K.
Homeowners across St Austell come to us for triple glazed timber windows after a uPVC replacement has aged badly. Timber is the material you specify when you intend to still be happy with it in twenty years.
What is included
- Glazing beaded internally, so the sealed units can be replaced without disturbing the external finish.
- Kiln-dried to 12% moisture content before machining, so the sections stay true once they are installed.
- Stainless or solid brass ironmongery, because plated steel fails first and takes the finish with it.
- Glazing beaded internally, so the sealed units can be replaced without disturbing the external finish.
Timber moves. The craft in triple glazing is anticipating exactly how much, in St Austell conditions, and detailing the joints and finish so that movement never becomes a problem.

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.
