Woodfellas. Fairfield-based timber window makers. We build, renovate, and put in wooden windows from our Fairfield premises, serving houses and commercial properties right across Central Scotland.
Not a single window we make without being custom-built. Ethically sourced treated pine or hardwood, double glazing, and upgraded security, all standard.
Whether you need sash and case windows for a Victorian tenement, casement windows for a modern extension, or a full set of new windows for any sort of property, we build them in-house and put them in ourselves.
What timber windows we make
We build two main types of timber window, each built for different properties and specifications. Whichever you choose, both are made in treated pine or hardwood and both feature double-glazed sealed units as standard.
Sash windows
The classic Scottish window, and still the go-to.
Sash windows slide up and down within a timber box frame, using a system of weighted cords and pulleys doing the work. They’re the original window type on most of Fairfield’s Victorian and Edwardian tenements, and the correct replacement for listed buildings and conservation area properties where sash and case was the original design.
Whether your sash windows need refurbishing, repairing, or replacing altogether, we make custom ones that replicate the period profiles and proportions, while still giving you modern thermal and acoustic performance.
Here’s the thing: restoring your original frames with draught-proofing and double glazing upgrades is often the smartest call if the frames are still solid. We always do a full inspection before suggesting any replacement.

Outward-opening casement windows
Casement windows open outward on hinges, larger opening for ventilation, easy cleaning from inside. You’ll see them across Fairfield properties dating from the 1920s onwards, and on extensions, dormers, and newer builds.
We produce custom timber casement windows in side hung, top hung, and fixed styles. Like our sash windows, every casement is made to measure and double glazed as standard.

Why timber windows are the right choice
Timber has been the leading window material for hundreds of years. Not just tradition, it genuinely outperforms UPVC and aluminium in several areas that matter to property owners.
Timber’s natural insulation
The frame counts, not just the glass. Timber conducts heat far less easily than aluminium and outperforms UPVC at the equivalent frame width, giving better thermal performance from the frame itself, before the double glazing even gets involved.
Scotland’s not exactly warm, and energy costs are no joke, so the fact that timber frames keep heat in better makes a real impact to what you spend.
Repair, don’t replace
Things get damaged. With timber, that’s not the end of the story. You can fix it.
Rot in a sill? Take it out, fit new timber. Damaged frame part? Rebuild it. UPVC isn’t repairable: it fails, it goes to landfill, you start again.
Think about it: over the lifespan of a property, being able to repair and maintain timber windows rather than going for full replacement cuts serious money and cuts a lot of waste.
Timber and sustainability
Every length of timber we use is sourced from ethically managed forests.
Stores carbon as long as it ages, then biodegrades naturally. No landfill, no harmful process. UPVC is plastic from oil, and aluminium production is highly carbon-heavy. The contrast doesn’t need explaining.
If you care about the carbon footprint of your house, timber is the clear choice.
Beauty and value
Pick up a timber window sash and you notice it, heft, thickness, natural grain. No synthetic material can replicate that.
On a traditional sandstone tenement, a light stone villa, or a period Scottish cottage, timber windows produce an visual rightness that UPVC consistently fails to replicate.
And they contribute real value to a property, especially period homes where original or sympathetic features are what buyers look for.
Double glazing in timber windows
Every single window we produce, sash or casement, features double-glazed sealed units included as standard. Always.
The sealed unit sits within the timber frame and works with two panes of glass with a cavity. The effect is less heat transfer and improved sound insulation.
Put that double glazing together with the inherent thermal qualities of the timber frame, and you’ve got excellent thermal and acoustic performance across both sash and casement.
Need glazing bars for a traditional divided-light appearance? We can add those too.
Older frames. Single glazed. Still structurally sound? We can in many cases upgrade to double glazing as part of a restoration. Existing frames stay. Performance gets better. No full replacement.
This represents a common job on Fairfield’s older properties, where solidly built original sash windows are well-built but single glazing admits cold air and road noise.
Every unit we put in: satisfies the latest building regulations for thermal standards.

Timber windows for conservation areas
Scotland contains in excess of 600 officially recognised conservation areas.
Property in a conservation area? UPVC: not acceptable. Council will likely require replacements mirroring the original. Material, design, profile.
Having produced timber windows for conservation area and listed building properties throughout Scotland for over 20 years, we have a solid understanding of what the council expects.
Consent conditions, planning conditions, modern performance, we handle it all. And our sash and case windows page covers the regulations in more detail for anyone who wants to know more.
Timber types
Two timber types, and that’s what we use across all window range.
The most requested choice is treated pine. It’s pressure-treated to resist rot and decay, accepts a painted finish well, and performs well in Fairfield’s rain-heavy weather.
If a natural timber finish is preferred, or if extra longevity is called for, hardwood is the choice. It’s inherently more wear-resistant and accepts stains and oils very well.
Not sure which timber to pick? We recommend the right timber for each job based on the property, the exposure level, and the finish you want.
Timber windows FAQ
What timber windows can you make?
Sash and case is the traditional Fairfield window, sliding vertically in a timber box frame, that’s one type. Casement windows are hinged and open outward, that’s the other. Both are offered in treated pine or hardwood. And we produce fixed window panels too, for any opening setup.
Are timber windows worth it over UPVC?
Three things: results, longevity, looks. Timber wins on all three. More effective insulation at the same frame thickness. Significantly longer lifespan when maintained. Repairable, not fully replaced. And it’s the only material accepted for listed buildings, strongly favoured in conservation areas too.
Is it possible to replace single glazing in timber windows?
In most cases, yes! If your existing frames are in solid condition, we can convert to double-glazed sealed units as part of a restoration, keeping the original frames and appearance while lifting thermal and acoustic results.
