By midsummer Ferndown has about 16 h 31 min of daylight, but in December only around 7 h 56 min, with the noon sun at about 16°. Triple glazing keeps more heat in during those long, dark months; big south and west windows may suit solar-control glass for summer.

Rules for glass-only replacement in England

In England, replacement windows must meet 1.4 W/m²K, or a Window Energy Rating of band B or better. Replacement windows are a controlled fitting. A competent person scheme installer (such as FENSA or Certass) self-certifies the work and notifies the council within 30 days; otherwise a building control body approves it.

Before ordering: Replacing windows on a house is normally permitted development if the new ones look similar. New upper-floor windows in a side wall must be obscure glazed and fixed, or open only above 1.7 m. Flats and maisonettes have no householder permitted development rights, so a change that alters their appearance needs planning permission. An Article 4 direction in a conservation area may mean permission is needed, and listed buildings need listed building consent.

How it works

The surveyor measures every opening, checks ventilation, escape windows and safety-glass zones, and talks through styles. Your written quote lists each item with its glass build-up and U-value, and the price is fixed for that specification.

  • Free survey and a written quote fixed for the specification
  • Glass build-up and whole-window U-value on every quote
  • Written handover pack at the end of the job
  • Guarantees on frames, units and fitting in writing

Questions from Ferndown

Will heavier glass damage my hinges?

It can. Triple units are about 50% heavier, so hinges and packers are checked and upgraded where needed.

Can I put triple glazing in my existing windows?

Usually not in a way that helps. Most frames take up to about 28 mm units; a triple unit that thin performs about the same as, or worse than, good double glazing. We check your frames before recommending anything.

Yes. We arrange surveys and fitting in Ferndown and across Dorset. Send your postcode and the windows or doors you want replaced, and we will book a free survey.

How long does it take to get triple glazed replacement sealed units fitted in Ferndown?
