Woodfellas are Old Kilpatrick’s leading timber window specialists, making, restoring, and fitting wooden windows from a Old Kilpatrick workshop that works across residential properties and commercial properties right across Central Scotland.
Not a single window leaves our workshop without being built to order. Sustainably sourced treated pine or hardwood, double glazing, and improved security, all standard.
Tenement, extension, any property. Sash and case, casement, or a complete replacement set: we build ourselves and fit ourselves.
Our timber window range
Two main types of timber window, each built for different properties and requirements. Both offered in treated pine or hardwood, and both come with double-glazed sealed units as standard.
Sash window types
Scotland’s classic window design.
Sash windows move vertically within a timber box frame, with a system of weighted cords and pulleys doing the work. They’re the standard window type on most of Old Kilpatrick’s Victorian and Edwardian tenements, and the only accepted replacement for listed buildings and conservation area properties where sash and case was the original design.
We renovate, sort, and make custom sash windows that precisely match period profiles and proportions while achieving modern thermal and acoustic results.
Restoration typically includes draught-proofing and double glazing upgrades, and it’s the smartest call where the existing frames are sound. We do full surveys before recommending any replacement.
Outward-opening casement windows
Casement windows open out on hinges, wider opening for airflow, easy access from inside. You’ll find them all over Old Kilpatrick properties built from the 1920s onwards, and on extensions, dormers, and newer builds.
Side hung, top hung, fixed, we produce custom timber casement windows in all three styles. Like our sash windows, every single one is built to order and double glazed as standard.
Our timber casement windows section covers all available designs and configurations in complete detail.
Why choose timber for your windows
Hundreds of years of timber windows, and they’re not still around out of habit. Timber genuinely outperforms UPVC and aluminium in a number of areas that make a difference to homeowners. The record speak for themselves.
Timber’s natural insulation
Timber transfers heat far less quickly than aluminium and outperforms UPVC at equivalent frame thicknesses. The result is stronger thermal performance from the frame itself, and that’s before the double glazing comes into it.
Scotland depends on central heating. A timber frame’s thermal characteristics make a tangible effect to what you spend, and that difference shows up over the years.
Timber windows, fix before replace
The key thing about timber windows is that if something gets damaged, you can fix it.
Got rot in a sill? You take it out and fit fresh timber. Damaged part of frame? Rebuild. With UPVC, you don’t have that option. When it goes, the entire thing ends up in landfill and you’re starting over.
Year after year, repair and maintain rather than start over. Over the lifetime of a property, that adds up to real cost saved and a lot less waste going to landfill.
Sustainability
Every piece of timber we use is sourced from ethically managed woodland.
Timber is a sustainable resource that holds carbon throughout its working life and biodegrades naturally at end of life. UPVC is a plastic derived from oil, and aluminium production is highly energy-intensive, worth knowing if the environment matters to you.
Care about your property’s environmental impact? Timber. Obvious option.
Appeal and property value
Timber windows have a weight, a character, and a natural grain that no man-made alternative can match.
On a traditional sandstone tenement, a light stone villa, or a period Scottish cottage, timber windows look right in a way UPVC just can’t. Worth considering if aesthetics matter to you.
They bring genuine property value too. Especially older properties. Original or sympathetic features count to buyers.
Double glazed timber windows
Sash or casement. Every window. Double-glazed sealed units included as standard.
The sealed unit fits inside the timber frame: it’s two panes of glass with a sealed cavity between them, which limits heat transfer and lifts sound insulation.
Put that double glazing together with the natural thermal qualities of the timber frame, and you’ve got excellent thermal and acoustic results across both sash and casement.
Need glazing bars for a traditional divided-light look? We can fit those as well.
Where older timber windows are solid but single glazed, we can often upgrade them to double glazing as part of a restoration, preserving the original frames and boosting thermal performance without needing a full replacement.
This is a regular project on Old Kilpatrick’s older properties, where well-built original sash windows perform structurally well but single glazing lets in cold and street noise.
And every unit we fit satisfies the latest building regulations for thermal performance, so you’re covered.
Timber windows in listed buildings and conservation areas
Scotland has more than 600 recognised conservation areas, and being in one changes what you can do with your windows.
Conservation area, and your windows need replacing? UPVC is not an approved material, your local council will likely require replacements that match the original in material, design, and profile. It’s a firm requirement.
We’ve been making timber windows for conservation area and listed building properties across Scotland for over 20 years. We understand what the council expects, so you don’t have to work it out yourself.
Consent conditions, planning conditions, modern performance, we cover all of it. And our sash and case windows page covers the regulations in more detail for anyone who wants to know more.
Timber types
Across all our window products, we use two types of timber.
Treated pine: most requested option. Pressure-treated against rot and decay. Takes a painted finish well. Works well in Old Kilpatrick’s damp weather.
If you want a natural timber finish, or if you need something more durable, hardwood is the one, it’s naturally more resistant to deterioration and it takes stains and oils really well.
Property. Exposure level. Finish. We help you choose the right timber for each job.
FAQ, timber windows
What types of timber windows do you make?
We produce two main types: sash and case windows and casement windows, both made in treated pine or hardwood. Sash and case are the traditional Old Kilpatrick design, sliding up and down within a timber box frame. Casement windows are hinged and swing outward. We also produce fixed window panels to match any opening setup.
Are timber windows worth it over UPVC?
For results, lifespan, and looks? Yes, timber wins. It insulates more effectively at the same frame width, lasts a lot longer when maintained, and can be restored not replaced. It’s also the only material permitted for listed buildings and greatly favoured in conservation areas.
Can existing timber windows be converted to double glazing?
In many cases, yes. Where existing timber frames are in sound condition, we can switch the glazing to double-glazed sealed units as part of a restoration programme. This retains the original frames and character while improving thermal and acoustic standards.
