Straight advice on swapping glass only, and when it is worth it. Sealed unit replacement means changing only the glass in an existing frame.

Winter light and glass choice in Clydebank

By midsummer Clydebank has about 17 h 36 min of daylight, but in December only around 6 h 58 min, with the noon sun at about 11°. 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 Scotland

In Scotland, replacement windows must meet 1.6 W/m²K. Replacing a window or door, frame and all, does not need a building warrant, but the work must still meet the building standards.

Planning: Since May 2024, replacement windows on houses are widely permitted development, including in many conservation areas, with front elevations expected to match the existing closely; your council tells you if prior notification applies. Flats outside conservation areas generally need permission only if the opening size changes. Listed buildings need listed building consent.

How it works

After the free survey you get a written quote naming the frame system, the glass build-up and the whole-window U-value for every item. Windows are made to order, then fitted, sealed and made good, one opening at a time.

  • 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 Clydebank

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.

How much does a triple glazed sealed unit cost?

Where a frame can take one, our guide starts at £145 fitted for a small unit, inc VAT. Published UK figures of about £90 to £220 per unit are mostly for double units; triple units cost more.

Do I need permission for triple glazed replacement sealed units in Clydebank?

In Scotland, replacement windows on houses are widely permitted development since May 2024, with front elevations expected to match closely; listed buildings need consent. Check whether your street is in a conservation area or covered by an Article 4 direction before changing the style.

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

After the survey, typical manufacture time is 1 to 2 weeks for units, and replacing the units usually takes a few hours to a day.
