Millhill has its own timber window specialists and we’re called Woodfellas. We make, refurbish, and fit wooden windows from our base, serving homes and commercial properties across Central Scotland.
Custom-built, responsibly sourced timber, double glazing, upgraded security. Every window we produce is built the same way. No shortcuts.
Whatever you need, sash and case for a tenement, casement for a contemporary extension, or a full replacement set for any kind of property, we make them in-house and put them in ourselves.
Wooden windows we make
Two types. Two sets of requirements. We produce one for older properties, one for modern ones, but both are available in treated pine or hardwood, and both include double-glazed sealed units as standard.
Sash and case windows
Scotland’s original window design.
You know what makes sash windows clever? They slide vertically in a timber box frame using cords and counterbalance weights. They’re the classic window on most of Millhill’s Victorian and Edwardian tenements, and the required replacement for listed buildings and conservation area properties where sash and case was the original design.
We renovate, fix, and produce custom sash windows. Period profiles. Original proportions. Modern thermal and acoustic standards.
Here’s the thing: restoring your existing frames with draught-proofing and double glazing upgrades is often the smartest move if the frames are still in good shape. We always do a full inspection before suggesting replacement.
Standard casement windows
Casement windows are hinged and open outward to open, giving a wider opening for ventilation and making access from inside simple. They’re common on Millhill properties built from the 1920s onwards, as well as extensions, dormers, and new builds.
We produce custom timber casement windows in side hung, top hung, and fixed setups. Just like our sash windows, every casement is made to measure and double glazed as standard, no exceptions.

Why timber windows make sense
There’s a reason people have been installing timber windows in houses for generations, and it’s not just because they always have. Timber genuinely outperforms UPVC and aluminium in a number of areas that count to homeowners.
How timber insulates naturally
Did you know timber carries heat far less quickly than aluminium, and it outperforms UPVC at the equivalent frame thickness? That means better thermal efficiency from the frame itself, before you even consider the double glazing.
Scotland’s not exactly warm, and heating bills are no joke, so the fact that timber frames keep heat in better makes a genuine impact to what you spend.
Timber windows, repair before replace
If a timber window is damaged, the good news is you can fix it.
Rot in a sill can be cut out and new timber put in. A damaged part of frame can be repaired. UPVC can’t be repaired in the same way. When it fails, the whole unit ends up in landfill and you start over.
Think about it: over the lifespan of a property, being able to look after timber windows rather than going for full replacement cuts serious money and cuts a lot of waste.
Timber and sustainability
All our timber comes from sustainably managed forests.
Timber: renewable. Locks in carbon. Breaks down cleanly. UPVC: plastic from oil. Aluminium manufacturing: extremely energy-intensive.
If the carbon impact of your property matters to you, timber is the obvious option. It’s as simple as that.
Appeal and property value
Pick up a timber window sash and you feel it, weight, character, grain. No artificial material can match that.
On a traditional sandstone tenement, a blonde stone villa, or a traditional Scottish cottage, timber windows just belong in a way that UPVC just can’t pull off.
Value, too. On period properties, where period features are part of the appeal, timber windows add genuine value that UPVC never quite does.
Double glazed wooden windows
Sash or casement. Every window. Double-glazed sealed units included as standard.
The sealed unit is housed inside the timber frame: it’s two sheets of glass with a sealed cavity between them, which limits heat transfer and lifts sound insulation.
Put that double glazing together with the natural insulating characteristics of the timber frame, and you’ve got excellent thermal and acoustic performance across both sash and casement.
For properties that call for a traditional divided-light look, we can install glazing bars as an addition.
Got older timber windows that are still in good shape but only single glazed? In many cases we can upgrade them to double glazing as part of a restoration, keeping the existing frames and improving thermal performance without a full replacement.
It’s a particularly regular request on Millhill’s older properties, solid existing sash windows, but single glazing that lets in cold air and ambient noise. Easily fixed.
Every unit we fit complies with the latest building regulations for thermal standards. Always.
Conservation area timber windows
Scotland: over 600 recognised conservation areas.
Where a property is located in one of these areas, UPVC is not an approved window material, and the local planning authority will likely require replacements to match the existing window in material, design, and profile.
Over 20 years making timber windows for conservation areas and listed buildings throughout Scotland, we know what the council expects.
We can advise on consent requirements and build windows that tick every planning condition while still giving you modern performance. Our sash and case windows page covers the regulations in more depth if you want to read up.
Types of timber we use
Two timber types, and that’s what we stock across the entire window range.
Treated pine is the most chosen choice, and for good reasons. It’s pressure-treated to ward off rot and decay, takes a paint finish well, and works reliably in Millhill’s wet 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 deterioration and it takes stains and oils beautifully.
Property, exposure level, finish, three things we look at before recommending the right timber for each job. Get those right and the rest follows.
Timber windows FAQ
What types of timber windows do you make?
We produce sash and case windows and casement windows, both available in treated pine or hardwood. Sash and case are the traditional Millhill style, moving vertically within a timber box frame. Casement windows are hinged and open outward. We also build fixed window panels to match any window opening setup.
Are timber windows better than UPVC?
For results, longevity, and appearance? Yes, timber wins. It insulates more effectively at the comparable frame width, lasts significantly longer when looked after, and can be fixed not replaced. It’s also the sole material accepted for listed buildings and highly preferred in conservation areas.
Replacing single glazing to double glazing in timber windows, is it possible?
In most cases, yes. If your current timber frames are in good condition, we can upgrade the glazing to double-glazed sealed units as part of a restoration. The outcome is improved thermal and acoustic performance while retaining the original frames and appearance.
