Woodfellas. Fairlie-based timber window makers. We build, restore, and put in timber windows from our Fairlie workshop, working across homes and commercial properties across Central Scotland.
Every window we make is made to measure from sustainably sourced treated pine or hardwood timber, with double glazing and enhanced security installed as standard.
Sash and case for a tenement? Casements for a contemporary extension? A complete new set for any property? We produce them all in-house and fit ourselves.
What wooden windows we offer
We make two primary types of timber window, each designed for different properties and needs. Whichever you choose, both are made in treated pine or hardwood and both include double-glazed sealed units as standard.
Sash and case windows
Scotland’s classic window style.
Sash windows move up and down within a box frame, using a system of weighted cords and pulleys. They are the original window type on most of Fairlie’s period tenements, and they’re the only permitted replacement for listed buildings and conservation area properties where sash and case was the original design.
We restore, fix, and produce custom sash windows. Existing profiles. Existing proportions. Modern thermal and acoustic results.
Restoration usually covers draught-proofing and double glazing upgrades, and it’s the smartest option where the original frames are solid. We carry out full assessments before recommending replacement.

Traditional casement windows
The hinged window. Swings out, lets in more air, easy to reach from inside without leaning out. Casement windows became standard on Fairlie properties from the 1920s on, including extensions, dormers, and new builds.
Side hung, top hung, fixed, we manufacture custom timber casement windows in all three styles. Like our sash windows, every single one is custom-built and fitted with double glazing as standard.
All the designs, all the configurations, it’s on our timber casement windows section.
Why timber windows make sense
Centuries of timber windows, and they’re not still around out of habit. Timber actually outperforms UPVC and aluminium in multiple areas that matter to property owners. The record say it all.
Natural heat insulation
Timber conducts heat far less quickly than aluminium and outperforms UPVC at equivalent frame thicknesses. The result is superior thermal performance from the frame itself, and that’s before the double glazing comes into it.
In Scotland, where energy costs are a real challenge, the thermal properties of a timber frame make a genuine impact, and that adds up over time.
Repair, not replace
Timber window gets damaged? Good news: you can fix it.
Rot in a sill? Remove it and splice in fresh timber. Damaged part of frame? Repair. UPVC can’t do any of that. When it gives up, the whole unit ends up in landfill and you’re back to square one.
Over the lifetime of a property, the capacity to maintain and repair timber windows rather than replacing them represents significant savings in both money and waste.
Timber sustainability
Every bit of timber we use is procured from ethically managed forest.
Timber is a renewable resource, it stores carbon as it works and breaks down naturally when it’s done. UPVC is plastic derived from oil, and aluminium manufacturing takes a huge amount of energy.
If the carbon footprint of your home matters to you, timber is clearly the right choice. It’s not complicated.
Look and worth
Timber windows have a heft, a depth, and a grain that no artificial material can match.
Sandstone tenement. Pale stone villa. Traditional Scottish cottage. Timber windows belong. UPVC just can’t.
Timber windows also bring measurable value to a property, especially period properties where original or sympathetic features are part of the overall appeal.
Double glazed timber windows
Every window we build, sash or casement, features double-glazed sealed units as standard. No extras required.
The sealed unit sits inside the timber frame: it’s two panes of glass with a sealed cavity between them, which cuts down on heat transfer and boosts sound insulation.
When combined with the natural insulating qualities of the timber frame, a double-glazed timber window delivers excellent thermal and acoustic performance across both sash and casement styles.
Traditional divided-light appearance? We can add glazing bars, a straightforward addition that makes a big visual difference.
If your older timber windows are still in good condition but single glazed, we can often switch them to double glazing as part of a restoration. This preserves the existing frames and boosts performance without a full replacement.
It comes up a lot on Fairlie’s older properties, existing sash windows that are solid, but the single glazing allows in cold air and ambient noise like it’s not even there.
Every unit we put in: complies with the latest building regulations for thermal standards.

Timber windows and conservation areas
There are over 600 conservation areas across Scotland, a significant number.
In a conservation area? UPVC is not an permitted window material, and your local council may require replacements that replicate the original in material, design, and profile.
Over 20 years producing timber windows for conservation areas and listed buildings across Scotland. We know what the council expects.
We help with consent requirements. We make windows that meet planning condition. Modern performance included. Our sash and case windows page covers the regulations in more depth.
Timber types
Across all our window products, we stock two types of timber.
Treated pine is what most people go for, pressure-treated to resist rot and decay, accepts a painted finish well, and performs in Fairlie’s rain-heavy weather without a problem.
For properties where a natural timber finish is preferred, or where extra durability is called for, we stock hardwood, which is by nature more immune to deterioration and accepts stains and oils beautifully.
We’ll advise on which timber is right for your project based on the property, the exposure level, and what finish you’re after.
FAQ, timber windows
What timber windows can you make?
Sash and case is the traditional Fairlie window, sliding vertically in a timber box frame, that’s one type. Casement windows are hinged and swing outward, that’s the other. Both are available in treated pine or hardwood. And we build fixed window panels too, for any window opening configuration.
Are timber windows better than UPVC?
On results, lifespan, and appearance: yes. Timber insulates more effectively at the equivalent frame thickness, lasts significantly longer when looked after, and can be repaired rather than replaced when damage occurs. It’s also the sole material permitted for listed buildings and is greatly favoured in conservation areas.
Is it possible to replace single glazing in timber windows?
Most cases, yes. The current frames are solid, so we upgrade the glazing to double-glazed sealed units as part of a restoration programme. Existing frames stay, look stays, and the thermal and acoustic performance gets better, without a full replacement.
