If you need timber windows done right in Newarthill, Woodfellas are the ones to call. We make, renovate, and fit timber windows out of our Newarthill workshop, working across homes 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.
Tenements need sash and case, contemporary extensions want casement, and some properties need a full replacement set. Whatever the job, we build ourselves and install ourselves. No middlemen.
Our timber windows
We make two primary types of timber window, one built for older properties, one built for newer ones. Both are available in treated pine or hardwood, and both feature double-glazed sealed units as standard.
Sash window types
Scotland’s original window style.
Sash windows work on a clever system: they slide up and down in a box frame using cords and counterbalance weights. You’ll find them on most of Newarthill’s Victorian and Edwardian tenements, and if you’ve got a listed property or conservation area property, they’re the required replacement where sash and case was the existing design.
We restore, fix, and produce custom sash windows. Period profiles. Original proportions. Modern thermal and acoustic results.
The existing frames are solid, so why swap them? Restoration, draught-proofing and double glazing upgrades, is usually the better route. We complete full assessments first, before we ever recommend going further.

Standard casement windows
Casement windows open outward on hinges, wider opening for airflow, easy access from inside. You’ll find them across Newarthill properties dating from the 1920s onwards, and on extensions, dormers, and newer builds.
Side hung, top hung, fixed, three setups, all in custom timber. And like our sash windows, every casement we build is custom-built and double glazed as standard.

Why timber windows are the right choice
Timber has been the go-to window material for centuries, and it’s worth knowing why. It actually outperforms UPVC and aluminium in multiple areas that count to homeowners, and that’s not just tradition.
Timber’s natural insulation
The frame counts, not just the glass. Timber conducts heat far less quickly than aluminium and outperforms UPVC at the same frame width, giving superior thermal performance from the frame itself, before the double glazing even gets involved.
Scotland. Cold. Expensive to heat. A timber frame’s thermal characteristics make a tangible effect.
Repair, don’t replace
If a timber window is damaged, the good news is you can fix it.
Rot in a sill or bottom rail can be removed and new timber spliced in its place. A damaged section of frame can be repaired and restored. UPVC offers no such route: when it fails, the whole unit goes to landfill and everything starts again.
Over the working life of a property, the option to maintain and repair timber windows rather than replacing them means significant savings in both cost and material waste.
Environmental credentials
Every bit of timber we work with comes from sustainably managed woodland.
Timber is a replenishable resource that sequesters carbon throughout its working life and breaks down naturally at end of life. UPVC is a oil-derived plastic, and aluminium production is highly carbon-heavy.
Your property’s carbon impact matters to you? Then timber is the clear option. It always has been.
Character and value
There’s a weight, a character, and a texture to timber windows that synthetic materials simply can’t match.
On a sandstone tenement, a pale stone villa, or a period Scottish cottage, timber windows fit right in a way UPVC never quite manages. Worth considering if aesthetics count to you.
Timber windows also add measurable value to a property, particularly period properties where original or sympathetic features are part of the overall appeal.
Double-glazed timber windows
Every single window we make, sash or casement, includes double-glazed sealed units installed as standard. Always.
The sealed unit is housed inside the timber frame: it’s two sheets of glass with a sealed cavity between them, which cuts down on heat transfer and improves sound insulation.
The timber frame’s natural insulating properties combined with the double-glazed sealed unit achieve strong thermal and acoustic results across both window types. That’s what you get as standard.
For properties that need a traditional divided-light appearance, we can fit glazing bars as an addition.
Got older timber windows that are still in good shape but only single glazed? In a lot of cases we can upgrade them to double glazing as part of a restoration programme, keeping the existing frames and improving performance without a full replacement.
This is a regular job on Newarthill’s older properties. The existing sash windows are well-built, but the single glazing allows in cold air and street noise, and upgrading to double glazing addresses both.
Every unit we fit: complies with the latest building regulations for thermal standards.

Timber windows in listed buildings and conservation areas
Scotland has more than 600 recognised conservation areas.
Conservation area, and your windows need attention? UPVC is not an acceptable material, your local council will often require replacements that match the original in material, design, and profile. It’s a firm requirement.
Over 20 years making timber windows for conservation areas and listed buildings throughout Scotland. We know what the council requires.
We can advise on consent conditions and produce windows that satisfy planning condition while giving you modern performance. Our sash and case windows page covers the regulations in more detail.
Types of timber we work with
Two timber types. That’s it. We use both for all window product range.
The most requested option is treated pine. It’s pressure-treated to prevent rot and decay, accepts a paint finish well, and works well in Newarthill’s wet climate.
For properties where a natural timber finish is wanted, or where added strength is needed, we offer hardwood, which is by nature more immune to damage and accepts stains and oils with excellent results.
Property. Exposure level. Finish. We advise on the right timber for each project.
Timber windows FAQ
What types of timber windows do you make?
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 Newarthill design, sliding vertically within a timber box frame. Casement windows are hinged and open out. We also build fixed window panels to suit any window opening setup.
Timber windows vs UPVC, which is better?
For results, lifespan, and looks? Yes, timber is the better choice. It insulates more effectively at the same frame width, lasts a lot longer when maintained, and can be restored rather than replaced. It’s also the sole material permitted for listed buildings and is highly preferred in conservation areas.
Can you replace single glazing with double glazing in existing timber windows?
In a significant number of cases, yes. Where current timber frames are in good condition, we can switch the glazing to double-glazed sealed units as part of a restoration. This retains the existing frames and character while lifting thermal and acoustic performance.
