Double Glazed Timber Windows in Preston
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 Preston 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 Preston 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 Preston and firm it up properly.

Questions
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.
Can you fit trickle vents?
Where Building Regulations require background ventilation, we design it into the head of the frame at manufacture. That looks far better and performs far better than a vent drilled through a finished frame on site.
Do you work on listed buildings?
Regularly. Listed building consent turns on detail — sightlines, glazing bar sections, opening method and glass type. We survey the existing joinery, record the profiles and produce drawings you can submit. We will not quote a detail we know will not pass.
