If you need timber windows done right in Anniesland, Woodfellas are the right choice. We produce, refurbish, and put in wooden windows out of our Anniesland base, covering houses and businesses throughout Central Scotland.
Custom-built, ethically sourced timber, double glazing, enhanced security. Every window we produce is made to the same standard. No shortcuts.
Whether you need sash and case windows for a Victorian tenement, casement windows for a newer extension, or a full set of replacement windows for any type of property, we produce them in-house and put them in ourselves.
Our range of timber windows
Two types. Two sets of requirements. We build one for older properties, one for modern ones, but both come in treated pine or hardwood, and both feature double-glazed sealed units as standard.
Sash window types
The traditional window style for Scottish properties.
You know what makes sash windows great? They move vertically in a timber box frame using cords and counterbalance weights. They’re the classic window on most of Anniesland’s period tenements, and the only accepted replacement for listed buildings and conservation area properties where sash and case was the existing design.
We restore, fix, and manufacture custom sash windows built to match existing profiles and proportions. The result is modern thermal and acoustic results in a window that fits right in.
A lot of the time, renovating the original frames, draught-proofing and double glazing, is the more sensible option if the frames themselves are still sound. We do a full assessment before recommending a replacement.

Casement windows
The hinged window. Swings out, lets in a wider flow of air, easy to clean from inside without leaning out. Casement windows became the norm on Anniesland properties from the 1920s on, including rear extensions, dormers, and newer builds.
We manufacture custom timber casement windows in side hung, top hung, and fixed styles. Just like our sash windows, every casement is custom-built and fitted with double glazing as standard, no exceptions.
Our timber casement windows page has more information on all listed options and configurations.
Why timber windows make sense
Generations of timber windows, and they’re not still around out of habit. Timber truly outperforms UPVC and aluminium in multiple areas that make a difference to households. The numbers say it all.
Timber’s natural insulation
Here’s something that surprises people: timber actually carries heat far less quickly than aluminium, and it outperforms UPVC at the same frame thickness. That means the frame itself is already doing more thermal work before you even add the double glazing.
Scotland. Cold. Expensive to heat. A timber frame’s thermal characteristics make a measurable impact.
Timber windows, fix before replace
The key thing about timber windows is that if something deteriorates, you can fix it.
Rot in a sill or bottom rail can be taken out and fresh timber fitted in. A damaged part of frame can be replaced in section. UPVC can’t be repaired in the same way. When it fails, the entire unit ends up in landfill and you start over.
Over the lifespan of a property, being able to look after timber windows rather than having to replace them cuts real cost and cuts down on waste.
Sustainability
The timber we use is sourced from responsibly managed woodland, every bit of it.
Timber locks in carbon and biodegrades cleanly, it’s a sustainable resource. UPVC is plastic made from oil, and aluminium manufacturing is highly carbon-heavy.
If the carbon footprint of your house is important to you, timber is clearly the right choice. It’s not complicated.
Beauty and appeal
Pick up a timber window sash and you feel it, substance, depth, natural grain. No artificial material can copy that.
On a traditional sandstone tenement, a pale stone villa, or a traditional Scottish cottage, timber windows look right in a way UPVC just can’t. Worth noting if aesthetics count to you.
Timber windows also bring tangible value to a property, particularly period homes where original or sympathetic features are part of the appeal.
Double glazing in wooden windows
Sash or casement, it doesn’t matter. Every window that we make comes with double-glazed sealed units included as standard. Always has been.
Two panes of glass. A cavity between them. The sealed unit sits inside the timber frame and manages the rest, limiting heat transfer, lifting sound insulation.
The timber frame’s inherent thermal characteristics combined with the double-glazed sealed unit achieve strong thermal and acoustic results across both window styles. That’s what you get as standard.
If your property requires a traditional divided-light look, we can install glazing bars, just let us know.
If your older timber windows are still structurally sound but single glazed, we can often switch them to double glazing as part of a restoration. This preserves the existing frames and boosts thermal performance without a full replacement.
It comes up a lot on Anniesland’s older properties, existing sash windows that are well-built, but the single glazing lets in cold and street noise like it’s not even there.
Every sealed unit we install satisfies the latest building regulations governing thermal standards.

Timber windows for conservation areas
Scotland: over 600 officially recognised conservation areas.
If your property is in one of these areas, UPVC isn’t an approved window material, and your local council may well require replacements that replicate the original in material, design, and profile.
Over 20 years manufacturing timber windows for conservation areas and listed buildings throughout Scotland. We understand what the council requires.
We can walk you through consent requirements and make windows that meet every planning condition while still giving you modern standards. Our sash and case windows page covers the regulations in more detail if you want to read up.
Types of timber we work with
Woodfellas stocks two types of timber for its full window product range.
Treated pine is what most customers pick, pressure-treated to ward off rot and decay, takes a painted finish well, and handles Anniesland’s rain-heavy weather without a problem.
If you want a natural timber look, or if you need something more durable, hardwood is the answer, it’s by nature more resistant to wear and it accepts stains and oils really well.
We recommend the right timber for each project, based on the property, its exposure, and the finish you need. Just ask and we’ll steer you right.
Common questions about timber windows
What types of timber windows do you produce?
We manufacture two main types: sash and case windows and casement windows, both made in treated pine or hardwood. Sash and case are the traditional Anniesland style, moving up and down within a box frame. Casement windows are hinged and open out. We also make fixed window panels to match any opening setup.
Is timber better than UPVC?
For results, longevity, and looks? Yes, timber is better. It insulates more effectively at the equivalent frame thickness, lasts significantly longer when looked after, and can be fixed rather than fully replaced. It’s also the sole material permitted for listed buildings and is strongly favoured in conservation areas.
Is it possible to upgrade single glazing in timber windows?
In many cases, yes. Where current timber frames are in good condition, we can convert the glazing to double-glazed sealed units as part of a restoration. This preserves the original frames and character while improving thermal and acoustic performance.
