Newton Stewart has its own timber window specialists and we’re called Woodfellas. We produce, restore, and put in timber windows from our premises, serving residential properties and business properties across Central Scotland.
Not a single window we produce without being built to order. Sustainably sourced treated pine or hardwood, double glazing, and upgraded security, all standard.
Whatever you need, sash and case for a tenement, casement for a newer extension, or a complete new set for any type of property, we build them in-house and install ourselves.
What timber windows we make
We build two main types of timber window, each designed for different properties and specifications. Whichever you pick, both are available in treated pine or hardwood and both include double-glazed sealed units as standard.
Sash window types
The traditional Scottish window, and it hasn’t changed.
Before UPVC, before aluminium, Newton Stewart’s Victorian and Edwardian tenements were built with sash windows, moving vertically in a box frame on cords and counterbalance weights. They’re still the required replacement for listed buildings and conservation area properties where sash and case was the original design.
The finest sash windows should look exactly like the original. We renovate, fix, and manufacture custom ones matching original profiles and proportions, while delivering modern thermal and acoustic results where it counts.
If your original frames are solid, restoration, draught-proofing and double glazing upgrades, is often the best call. We do full inspections before recommending any replacement, so you always know where you stand.

Casement windows
Hinged. Swing outward to open. Wider opening, easier cleaning from inside. Standard on Newton Stewart properties built from the 1920s on, including rear extensions, dormers, and new builds.
Side hung. Top hung. Fixed. We make custom timber casement windows in all three. Every one built to order. Fitted with double glazing as standard.

Why timber is the right call
Timber has been the top window material for centuries. Not just tradition, it truly outperforms UPVC and aluminium in multiple areas that count to homeowners.
Natural thermal performance
Did you know timber conducts heat far less easily than aluminium, and it outperforms UPVC at the same frame width? That means better thermal performance from the frame itself, before you even factor in the double glazing.
In Scotland, heating bills are a real concern. The thermal properties of a timber frame make a measurable effect to what you spend on heating, and it’s worth bearing in mind.
Repair, don’t replace
If a timber window is damaged, the good news is you can sort it.
Rot in a sill? Take it out, put in fresh timber. Damaged frame section? Rebuild it. UPVC isn’t repairable: it goes, it ends up in landfill, you start again.
Over the lifespan of a property, the ability to look after timber windows rather than carrying out full replacement means real savings in both cost and material waste.
Eco credentials
Every bit of timber we work with is sourced from ethically managed forests.
Locks in carbon as long as it ages, then biodegrades naturally. No landfill, no toxic process. UPVC is plastic from oil, and aluminium manufacturing is highly energy-intensive. The contrast is clear.
Concerned about your home’s environmental footprint? Timber. Obvious choice.
Appeal and property value
Timber windows have a substance, a depth, and a natural grain that no artificial alternative can replicate.
On a sandstone tenement, a light stone villa, or a period Scottish cottage, timber windows belong in a way UPVC never quite manages. Worth considering if the look count to you.
Value, too. On older properties, where period features are part of the appeal, timber windows bring tangible value that UPVC can’t match.
Double glazed timber windows
Sash or casement. Every window. Double-glazed sealed units fitted as standard.
The sealed unit sits inside the timber frame, two panes of glass with a cavity between them, reducing heat transfer and boosting sound insulation.
When combined with the inherent insulating characteristics of the timber frame, a double-glazed timber window gives you solid thermal and acoustic results across both sash and casement styles.
We can also fit glazing bars if your property needs a traditional divided-light look.
If your older timber windows are still structurally sound but single glazed, we can in many cases upgrade them to double glazing as part of a restoration. This retains the original frames and improves performance without a full replacement.
This represents a regular project on Newton Stewart’s older properties, where solidly built original sash windows perform structurally well but single glazing lets in cold air and street noise.
Every unit we put in is compliant with current building regulations for thermal performance. That’s guaranteed.

Timber windows for conservation areas and listed buildings
There are more than 600 conservation areas across Scotland, quite a total.
If your property is in one of these areas, UPVC is not an approved window material, and your local council might well insist on replacements that match the original in material, design, and profile.
We’ve been making timber windows for conservation areas and listed buildings throughout Scotland for over 20 years, so we know what the council requires, nothing new to us.
We can walk you through consent requirements and produce windows that satisfy planning condition while giving you modern performance. Our sash and case windows page covers the regulations in more depth.
Our timber types
Woodfellas works with two types of timber across its full window product range.
Treated pine represents the most frequently chosen option. It is pressure-treated to ward off rot and decay, takes a paint finish well, and holds up well in Newton Stewart’s damp weather.
If you prefer a natural timber look, or if you need something harder-wearing, hardwood is the answer, it’s naturally more immune to damage and it accepts stains and oils beautifully.
We’ll advise on which timber is most appropriate for your project based on the property, the exposure, and what finish you’re after.
Timber windows, frequently asked questions
What styles of timber windows do you offer?
We produce two main types: sash and case windows and casement windows, both offered in treated pine or hardwood. Sash and case are the traditional Newton Stewart style, sliding up and down within a box frame. Casement windows are hinged and swing outward. We also make fixed window panels to suit any opening setup.
Are timber windows better than UPVC?
On results, longevity, and appearance: yes. Timber insulates better at the same frame thickness, lasts considerably longer when looked after, and can be repaired rather than fully replaced when damage happens. It’s also the only material accepted for listed buildings and is strongly favoured in conservation areas.
Replacing single glazing to double glazing in timber windows, is it possible?
In many cases, yes. If your current timber frames are in solid condition, we can convert the glazing to double-glazed sealed units as part of a restoration. That keeps the existing frames and look while boosting thermal and acoustic performance.
