Winter light and glass choice in Hawick
By midsummer Hawick has about 17 h 29 min of daylight, but in December only around 7 h 04 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
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.
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.
- Every opening measured, including escape and vent needs
- Frames rated for the weight of triple glass
- Old windows removed and taken away
- Each opening closed up the same day
Questions from Hawick
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.
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.
Do I need permission for triple glazed replacement sealed units in Hawick?
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 Hawick?
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.
