Triple glazed uPVC windows for homes in Glasgow: measured on a free survey, made to order and fitted by installation teams working for us across Glasgow and the Clyde.

Winter light and glass choice in Glasgow
By midsummer Glasgow has about 17 h 35 min of daylight, but in December only around 6 h 59 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 uPVC 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.
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
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 Glasgow
Will triple glazed uPVC windows look bulky?
The frames look much the same as good double glazed uPVC. The glass unit is thicker, but that sits inside the frame, so from outside the difference is hard to spot.
How long do uPVC windows last?
The Energy Saving Trust gives 20 to 35 years for modern glazing. The sealed units carry their own guarantee, set out on your quote.
