In East Kilbride, midday sun in late December sits around 11° high, with roughly 7 h 00 min of daylight. For windows facing north or shaded by neighbours, cutting heat loss matters more than solar gain; on open south-facing glass, ask about a higher solar-gain unit.

Rules for glass-only replacement 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
You will know exactly what you are buying: the quote states the unit build-up, frame, finish, fitting work and how Building Regulations compliance is handled. On fitting day each opening is replaced and closed up before the team moves on.

Questions from East Kilbride
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.
Why are my windows misting between the panes?
The seal around the unit has failed and moist air has got in. Only replacing the unit fixes it.
How long does it take to get triple glazed replacement sealed units fitted in East Kilbride?
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.
