Triple glazed sash windows in Forfar
Triple glazed sash windows for homes in Forfar: measured on a free survey, made to order and fitted by installation teams working for us across Angus and Dundee.

Vertical sliding sashes, made triple glazed where the design allows. A sash window has one or two sashes that slide up and down in a box frame.
Winter light and glass choice in Forfar
Winter days in Forfar are short: about 6 h 48 min of daylight on 21 December, with the sun peaking near 10°. That low angle reaches deep into south-facing rooms, so we match the glass to each elevation rather than using one spec for the whole house.

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.
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.

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.
