A Georgian townhouse with plain white frames and no glazing bars looks like a different building, whatever the U-value inside the glass says.
If you’re restoring a period property, it’s easy to focus entirely on performance: U-values, seals, energy bills. The look of the finished window often gets treated as an afterthought instead.
The Advanced Group fits uPVC windows into historic and period properties across Scotland.
Colour and character detailing get planned alongside performance from the first survey, not bolted on after.
Colour options for a period property in Scotland
White is not compulsory. We fit uPVC windows in seven finishes.
On a historic property, the choice matters more than on a modern estate. The wrong colour can make a good window look out of place against old stone or render.
Woodgrain finishes for period character
Rosewood, Oak and Mahogany are woodgrain finishes, and they do more work on a historic property than anywhere else in the range. A Victorian villa or a farmhouse built with timber sash windows never had plain white frames originally.
A woodgrain finish keeps that period look, while the uPVC underneath does the work the old timber couldn’t continue.
Rosewood gives a warm reddish-brown grain that suits sandstone tenements and villas particularly well. Oak leans lighter, closer to the honey tone of old pine sashes before they were painted.
Mahogany goes darkest of the three, and it works beautifully on a grander Victorian or Edwardian frontage that can carry a stronger colour.
White, Cream, Black and Charcoal Grey on a period property
White still suits plenty of historic properties, particularly Georgian townhouses that were originally painted white or off-white around the sash boxes.
But cream reads a touch warmer against sandstone, which covers most Victorian tenements and villas across Glasgow and Edinburgh.
Black and Charcoal Grey suit a different kind of historic property: a converted mill, a stone steading, or a farmhouse extension. It creates a bolder, contemporary contrast works with the existing stonework there.
Character features that keep the look right
The glazing bars, horns, and mouldings on the frame matter just as much as colour. A lot of replacement windows skip them entirely.
Georgian glazing bars
Georgian and early Victorian sashes were built with small panes divided by timber glazing bars, because large sheets of glass weren’t yet affordable or available.
We replicate that pattern in the uPVC frame with astragal bars, so the window keeps the multi-pane look from the street.
Sash horns and traditional detailing
Original timber sash windows often have horns, a small decorative extension where the top and bottom sashes meet the frame. These were added in the Victorian era once glass got heavier.
Our uPVC sash windows include the same horns as standard on relevant styles, with sculpted mouldings that echo the original joinery.
Matching the window style to the property
A Georgian townhouse almost always used sash windows, while a Victorian or Edwardian villa might carry sash, casement, or both depending on the room.
The window style matters as much as the colour.
Matching ironmongery and hardware
But the frame and glass colour aren’t the only detail that matters.
We offer handles in black and traditional finishes to match the frame colour, rather than a single generic hardware option across the whole range.
Window styles we fit into historic properties
Sash windows
Most Georgian and Victorian properties across Scotland were built with vertical sliding sash windows.
Our uPVC sliding sash windows replace those old heritage window frames with spring balances rather than the original weights and cords. The sliding movement stays the same.
The horns and glazing bars keep the appearance intact, so the window still reads as a period sash from the street.
Casement windows
Side-hung and top-hung casement windows are common in rural cottages, farmhouses, and smaller period properties.
Our double glazed casement windows are built to the exact dimensions of each opening. The same Georgian bar options are available on casements too, where the property calls for them.
Listed building consent and conservation areas
Glazing for listed buildings works under different rules to a standard replacement.
Many of Scotland’s historic properties carry listed status, categorised by Historic Environment Scotland as Category A, B, or C.
Listed building consent from your local authority is a legal requirement before altering windows on any listed property. Category A and B buildings are unlikely to get approval for full uPVC replacement, though the exact answer depends on the individual building and its setting.
Most historic and period homes, though, aren’t listed at all.
If your property sits outside a conservation area and carries no listed status, permitted development applies. Standard uPVC double glazing can go ahead without a planning application in that case.
Our surveyors will always check and tell you honestly if our innovative uPVC windows are suited to your property.
If they aren’t, due to listed building regulations, we will guide you towards potential alternatives so your home gets the upgrade it deserves.
Energy efficiency without losing the character
A single pane of old glass has a U-value of around 5.0 W/m²K. Our standard double glazed units reach 1.4 W/m²K as standard, reducing heat loss through the glass by around 70%.
The glass provides the insulation and thermal performance. The frame colour and detailing are a separate choice entirely, so that improvement holds whatever colour or glazing bar pattern sits on top.
You can reduce that further to 1.2 W/m²K, and triple glazing brings the whole window down to 0.8 W/m²K if you want to go further. None of that changes how the frame looks from the street.
Better sealing also cuts the draughts and condensation that damage timber sills and plaster in an older property, on top of the heat loss.
How installation works in a historic home
- Free home survey – our surveyor measures every opening, records the existing glazing bar pattern and colour, and confirms your listed or conservation area status.
- Design and manufacture – each window is built to match the original style, including horns, astragal bars, and your chosen colour finish.
- Careful removal – old frames come out one at a time, with the opening cleared and inspected before the new unit goes in.
- Fitting and sealing – the frame is packed, levelled, and sealed to the actual shape of the opening.
- Finish and clean-up – surrounds are dressed to match, and all old frames and waste are removed before we leave..

Double glazing for historic homes: your questions answered
Will uPVC windows look right on a listed or period building?
Yes, provided the colour, glazing bar pattern, and horns match the original style. A plain white flat-panel window looks wrong on a Georgian or Victorian frontage. The same window in the right woodgrain colour, with astragal bars and horns, reads correctly from the street.
Do I need planning permission for double glazing in a historic home?
Only if your property is listed or sits in a conservation area. Most historic homes are neither, and standard replacement is permitted development. Listed buildings need consent from your local authority, and secondary glazing is usually the accepted alternative where full replacement isn’t approved.
What colour should I choose for a period property?
It depends on the era and the building material. Rosewood, Oak, or Mahogany woodgrain suit most Victorian and Edwardian stone properties. White suits Georgian townhouses that were originally painted pale. Black or Charcoal Grey work on converted mills, steadings, and bolder farmhouse extensions.
Can I get Georgian bars and horns on uPVC windows?
Yes, both are available as standard on our relevant sash and casement styles. They’re planned into the survey alongside your colour choice, rather than added as an afterthought.
