Honest advice on which sashes can take a full triple unit. A sash window has one or two sashes that slide up and down in a box frame.
Winter light and glass choice in Dunoon
By midsummer Dunoon has about 17 h 37 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 sash windows in Scotland
The rules for replacement windows in Scotland are set by the Building Standards Technical Handbook (Domestic), section 6: 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.
Before ordering: 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
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.
- Survey by arrangement, then 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 Dunoon
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.
Can I keep my original sash boxes?
Sometimes. A timber specialist can fit new sashes into sound original boxes, but the glass thickness is limited by the sash depth.
Do you fit triple glazed sash windows in Dunoon?
By arrangement. Dunoon (PA23) is a remote or island district, so we confirm availability before booking a survey and show any travel or access costs separately on your quote.
Do I need permission for triple glazed sash windows in Dunoon?
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.
