Heritage Slim Double Glazing in Richmond upon Thames
Slim-profile sealed units let you double glaze a period sash or Georgian bar window without fattening the glazing bars.
We treat heritage slim double glazing in Richmond upon Thames as joinery rather than a product line. That means real sections, real ironmongery and a finish specified for the exposure the building actually gets.
What is included
- Micro-porous finishes that let the timber breathe rather than trapping moisture behind a hard film.
- Factory-finished in controlled conditions — three coats minimum, fully cured before delivery.
- End-grain sealed at every cut before assembly — the single detail that decides whether joinery rots.
- Micro-porous finishes that let the timber breathe rather than trapping moisture behind a hard film.

Guide price →Questions
Do you take away the old windows?
Yes. Removal and responsible disposal are included, along with making good internally. We work one opening at a time so the property is never left open, and we clear the site each day.
How much disruption should I expect?
Less than most people fear. A straightforward replacement is one opening at a time, typically two to four windows a day. Scaffolding is only needed on higher elevations. We protect floors and furniture and leave the site clean each evening.
How long do hardwood windows actually last?
Properly specified and maintained hardwood joinery has a realistic service life of 60 years or more. The timber is rarely what fails — it is the finish and the seals, and both are renewable. That is the fundamental advantage over uPVC, where a failed unit or a distorted frame means the whole window goes.
Are timber windows warm enough for Building Regulations?
Yes, comfortably. Timber is a natural insulator with far lower conductivity than aluminium or steel. A standard hardwood double-glazed window achieves around 1.2–1.4 W/m²K whole-window, against a 1.4 requirement for replacements. Triple glazing in a deeper section will reach roughly 0.8.
