Rules for sash windows 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.

Questions from Renfrew
Are uPVC sashes allowed in conservation areas?
It depends on the council and any Article 4 direction. Timber is often expected on front elevations. Check before ordering.
Will triple glazing make my sashes heavy to lift?
The balances are sized for the sash weight, so they should slide smoothly. Heavier sashes use stronger balances or weights.
Do I need permission for triple glazed sash windows in Renfrew?
