Woodfellas are Fernhill’s leading timber window makers, making, restoring, and fitting wooden windows from a Fernhill workshop that covers residential properties and business properties right across Central Scotland.
Every window is made to measure. Ethically sourced treated pine or hardwood. Double glazing and enhanced security as standard.
Sash and case for a tenement, casements for a modern extension, or a complete set of new windows for whatever sort of property you’ve got, we build them all in-house and install ourselves.
Our timber windows
We make two main types of timber window, each designed for different properties and specifications. Whichever you go for, both are made in treated pine or hardwood and both feature double-glazed sealed units as standard.
Sash windows
The traditional Scottish window design.
You know what makes sash windows special? They move up and down in a box frame using weighted cords and pulleys. They’re the standard window on most of Fernhill’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, repair, and manufacture custom sash windows that replicate the period profiles and proportions while achieving modern thermal and acoustic standards.
Here’s the thing: renovating your existing frames with draught-proofing and double glazing upgrades is often the smartest call if the frames are still in good shape. We always do a full assessment before recommending any replacement.

Standard casement windows
Casement windows are the hinged type: they open outward to open, which gives you a larger opening for ventilation and means you can clean them easily from inside. They’re common on Fernhill properties dating from the 1920s on, and they’re the standard option for extensions, dormers, and newer builds.
We build custom timber casement windows in side hung, top hung, and fixed arrangements, so whatever configuration you need, we can make it. And like our sash windows, every casement is built to your size and double glazed as standard.

Why timber makes sense for windows
Centuries of timber windows, and they’re not still around out of habit. Timber actually outperforms UPVC and aluminium in multiple areas that make a difference to households. The numbers speak for themselves.
How timber insulates naturally
Here’s something that trips up people: timber actually carries heat far less easily than aluminium, and it outperforms UPVC at the comparable frame width. That means the frame itself is doing more thermal work before you even consider the double glazing.
Scotland runs on central heating. A timber frame’s insulating properties make a measurable impact to what you pay, and that saving shows up over the years.
Repair, don’t replace
Timber window gets damaged? You can repair it.
Rot in a sill or bottom rail can be taken out and new timber spliced in. A damaged part of frame can be rebuilt. UPVC can’t be repaired in the same way. When it breaks down, the entire unit goes to landfill and you start again.
Over the lifespan of a property, the capacity to look after timber windows rather than replacing them means significant savings in both cost and waste.
Environmental sustainability
The timber we work with comes from sustainably managed woodland, every piece of it.
Timber is a sustainable material, it holds carbon as it ages and biodegrades naturally when it’s done. UPVC is plastic made from oil, and aluminium production takes a huge amount of power.
Concerned about your property’s carbon footprint? Timber. Clear choice.
The character and value of timber windows
There’s a substance, a depth, and a grain to timber windows that synthetic materials just can’t match.
On a sandstone tenement, a blonde stone villa, or a traditional Scottish cottage, timber windows belong in a way UPVC just can’t. Worth noting if the look count to you.
Value, too. On period homes, where original or sympathetic features are part of what makes them special, timber windows contribute real value that UPVC never quite does.
Double glazing in timber windows
Every window we make, sash or casement, comes with double-glazed sealed units fitted. No extras required.
The sealed unit is housed within the timber frame, employing two panes of glass separated by a sealed cavity to cut heat transfer and lift sound insulation.
Put that double glazing together with the inherent insulating characteristics of the timber frame, and you’ve got excellent thermal and acoustic results across both sash and casement.
We can also install glazing bars if your property calls for a traditional divided-light appearance.
Where older timber windows remain solid but single glazed, we can often switch them to double glazing as part of a restoration, retaining the existing frames and boosting performance without necessitating a full replacement.
This is a common job on Fernhill’s older properties, where well-constructed existing sash windows perform structurally well but single glazing lets in cold and ambient noise.
Every unit we put in complies with the latest building regulations for thermal performance. Always.

Conservation area timber windows
There are more than 600 conservation areas in Scotland, quite a number.
In a conservation area? UPVC is not an acceptable window material, and your local council will likely require replacements that match the original in material, design, and profile.
We’ve been making timber windows for conservation areas and listed buildings across Scotland for over 20 years, so we know exactly what the council expects, nothing new to us.
We advise on consent conditions. We build windows that satisfy planning condition. Modern performance included. Our sash and case windows page covers the regulations in more detail.
Our timber types
Woodfellas uses two types of timber across its entire window product range.
Most people go for treated pine. It’s pressure-treated to ward off rot and decay, accepts a paint finish well, and holds up in Fernhill’s damp conditions with no trouble.
Want a natural timber finish or need extra strength? Hardwood is what you need, inherently more resistant to wear, and it takes stains and oils so well.
Property. Exposure level. Finish. We recommend the right timber for each job.
Timber windows, frequently asked questions
What timber windows can you make?
We produce both sash and case windows and casement windows, made in treated pine or hardwood. Sash and case windows are the traditional Fernhill style, working by moving up and down within a box frame. Casement windows are hinged and open outward. We also produce fixed window panels to suit any opening configuration.
Are timber windows worth it over UPVC?
For results, longevity, and looks? Yes, timber wins. It insulates better at the same frame thickness, lasts significantly longer when maintained, and can be repaired not replaced. It’s also the only material accepted for listed buildings and highly preferred in conservation areas.
Can existing timber windows be upgraded to double glazing?
In most cases, yes. If your current timber frames are in solid condition, we can convert the glazing to double-glazed sealed units as part of a restoration. That retains the existing frames and look while lifting thermal and acoustic results.
