Double Glazed Timber Windows in Islington
Argon-filled, low-e sealed units in hardwood frames — typically 1.2–1.4 W/m²K whole-window, comfortably Building Regs compliant.
We build double glazed timber windows for Islington homes to the size of the hole in the wall, not to the nearest standard unit. That is the whole reason to specify timber in the first place.
What is included
- Engineered laminated sections on anything over 1.2m, which resist bowing far better than solid stock.
- Weathered cills with a proper drip groove, so water leaves the timber instead of tracking back under it.
- Trickle ventilation designed into the head where Building Regulations require it, not drilled in afterwards.
- Engineered laminated sections on anything over 1.2m, which resist bowing far better than solid stock.
Our double glazing are made from kiln-dried hardwood, machined in the workshop and factory-finished before they ever reach a Islington site. Wet-brushing on site is where timber windows get a bad name.
Ask for the guide price first. If the range works for your budget, we will book a survey in Islington and firm it up properly.

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.
