Woodfellas are Stonehouse’s established timber window makers, manufacturing, renovating, and installing timber windows from a Stonehouse workshop that works across houses and commercial properties across Central Scotland.
Not a single window leaves our workshop without being made to measure. Responsibly sourced treated pine or hardwood, double glazing, and upgraded security, all standard.
Tenements need sash and case, newer extensions want casement, and some properties need a complete replacement set. Whatever the job, we produce in-house and put them in ourselves. No middlemen.
What timber windows we make
Two types. Two sets of requirements. We make one for older properties, one for modern ones, but both come in treated pine or hardwood, and both come with double-glazed sealed units as standard.
Sash window types
The traditional Scottish window type.
Sash windows slide vertically within a box frame, using a system of weighted cords and pulleys. They represent the historic window type on most of Stonehouse’s Victorian and Edwardian tenements, and they’re the only permitted replacement for listed buildings and conservation area properties where sash and case was the existing design.
We renovate, sort, and build custom sash windows designed to match period profiles and proportions. The result is modern thermal and acoustic standards in a window that fits right in.
A lot of the time, restoring the original frames, draught-proofing and double glazing, is the more sensible call if the frames themselves are still in good shape. We always do a full survey before suggesting full replacement.
Casement windows
The hinged window. Swings out, lets in more ventilation, easy to reach from inside with no fuss. Casement windows became standard on Stonehouse properties from the 1920s on, including extensions, dormers, and newer builds.
Side hung, top hung, fixed, we manufacture custom timber casement windows in all three setups. Like our sash windows, every single one is custom-built and fitted with double glazing as standard.
Our timber casement windows page has more detail on all available styles and configurations.
Why timber is the right choice
Timber windows have been around for generations, and there’s a reason they’ve stayed the go-to. It’s not just tradition, timber actually outperforms UPVC and aluminium in a number of areas that make a difference to households.
Natural thermal performance
Timber conducts heat far less easily than aluminium and outperforms UPVC at comparable frame widths. This translates to better thermal performance from the frame itself, before the double glazing is even considered.
Scotland runs on central heating. A timber frame’s thermal characteristics make a tangible effect to what you spend, and that saving shows up over time.
Fix it, don’t replace it
Things get damaged. With timber, that’s not the end of the story. You can fix it.
Got rot in a sill? You remove it and splice in fresh timber. Damaged part of frame? Replace in section. With UPVC, you don’t have that option. When it goes, the entire thing goes to landfill and you’re starting over.
Over the lifespan of a property, the capacity to look after timber windows rather than carrying out full replacement means genuine savings in both money and material waste.
Sustainability
Every piece of timber we use is sourced from responsibly managed forest, that’s how we operate.
Timber is a renewable material that stores carbon throughout its working life and biodegrades cleanly at end of life. UPVC is a plastic made from oil, and aluminium production is highly energy-intensive, worth knowing if the environment matters to you.
If you care about the carbon impact of your house, timber is the obvious option.
Character and value
Weight. Depth. Grain. No man-made alternative can copy it.
Traditional sandstone tenement. Pale stone villa. Period Scottish cottage. Put timber windows in and they belong. Put UPVC in and something’s slightly off, it never quite manages that same rightness.
They bring tangible property value too. Especially period properties. Original or sympathetic features matter to potential buyers.
Double glazing in wooden windows
Sash or casement. Every window. Double-glazed sealed units fitted as standard.
The sealed unit fits inside the timber frame, two layers of glass with a sealed cavity between them, reducing heat transfer and lifting sound insulation.
Combine the timber frame’s natural insulating characteristics with double glazing and you get solid thermal and acoustic performance across both window styles.
We can also add glazing bars if your property requires a traditional divided-light appearance.
Got older timber windows that are still solid but only single glazed? In a lot of cases we can convert them to double glazing as part of a restoration, preserving the existing frames and boosting thermal performance without a full replacement.
It’s a particularly common project on Stonehouse’s older properties, well-built existing sash windows, but single glazing that lets in cold and road noise. Readily fixed.
Every sealed unit we install satisfies current building regulations governing thermal standards.
Listed buildings timber windows
Scotland has more than 600 officially recognised conservation areas, and if you’re in one, it matters.
Where a property is located in one of these areas, UPVC is not an approved window material, and the local planning authority may require replacements to match the original window in material, design, and profile.
We’ve been manufacturing timber windows for conservation area and listed building properties throughout Scotland for over 20 years. We understand what the council requires, so you don’t have to work it out yourself.
We can help with consent requirements and build windows that satisfy planning condition while delivering modern performance. If you want more on the regulations, our sash and case windows page covers them in detail.
Types of timber we work with
We use two timber types across the entire window product range, here’s what you need to know about each.
Most customers pick treated pine. It’s pressure-treated to resist rot and decay, takes a paint finish well, and holds up in Stonehouse’s wet weather without any issue.
For properties where a natural timber finish is preferred, or where additional strength is needed, we offer hardwood, which is inherently more resistant to damage and takes stains and oils with excellent results.
We help you choose the best timber for each job, taking into consideration the property age, its exposure, and the wanted finish.
Timber windows FAQ
What timber windows do you make?
Sash and case is the traditional Stonehouse window, sliding vertically in a timber box frame, that’s one type. Casement windows are hinged and swing out, that’s the other. Both come in treated pine or hardwood. And we make fixed window panels too, for any opening setup.
Is timber better than UPVC?
On all three counts, thermal performance, longevity, and looks, yes, timber is the superior choice. It insulates more effectively at equivalent frame widths, lasts considerably longer when properly maintained, and can be fixed rather than replaced when damage occurs. Timber is also the only material accepted for listed buildings and is greatly preferred in conservation areas.
Can you upgrade single glazing with double glazing in existing timber windows?
In many cases, yes. If your current timber frames are in sound condition, we can switch the glazing to double-glazed sealed units as part of a restoration. That preserves the original frames and appearance while lifting thermal and acoustic results.
