Chryston has its own timber window makers and we’re called Woodfellas. We make, refurbish, and put in wooden windows from our premises, covering homes and commercial properties throughout Central Scotland.
Each window is made to measure using ethically sourced treated pine or hardwood timber. Double glazing and upgraded security come as standard on every unit.
Whether you need sash and case windows for a period tenement, casement windows for a modern extension, or a full set of new windows for any type of property, we build them ourselves and install ourselves.
Our timber window lineup
Two types of timber window. Each designed for different properties and needs. Both available in treated pine or hardwood. Both featuring double-glazed sealed units as standard.
Sash and case windows
The traditional window design for Scottish properties.
Sash windows work on a clever system: they slide up and down in a box frame using weighted cords and pulleys. You’ll find them on most of Chryston’s period tenements, and if you’ve got a listed property or conservation area property, they’re the required replacement where sash and case was the original design.
We renovate, repair, and manufacture custom sash windows that nail the original profiles and proportions while delivering modern thermal and acoustic results.
A lot of the time, renovating the existing frames, draught-proofing and double glazing, is the smarter option if the frames themselves are still sound. We do a full survey before suggesting a replacement.

Outward-opening casement windows
Casement windows are the hinged type: they open out to open, which gives you a larger opening for ventilation and means you can clean them without trouble from inside. They’re common on Chryston properties built from the 1920s on, and they’re the natural choice for rear extensions, dormers, and new builds.
We manufacture custom timber casement windows in side hung, top hung, and fixed configurations. Just like our sash windows, every casement is custom-built and double glazed as standard, no exceptions.

Why timber is the right call
Timber has been the top window material for centuries. Not just tradition, it genuinely outperforms UPVC and aluminium in multiple areas that make a difference to homeowners.
Natural thermal insulation
Timber carries heat far less readily than aluminium and outperforms UPVC at equivalent frame thicknesses. The outcome is superior thermal performance from the frame itself, and that’s before the double glazing factors in.
Scotland. Cold. Expensive to heat. A timber frame’s thermal properties make a measurable effect.
Repair, don’t replace
Timber window gets damaged? Good news: you can sort it.
Rot in a sill or bottom rail? Take it out, fit new timber. Damaged frame part? Rebuild it. UPVC can’t be repaired: it fails, it goes to landfill, you start again.
Over the lifetime of a property, the ability to look after timber windows rather than carrying out full replacement represents significant savings in both money and waste.
Sustainability
We get all our timber from sustainably managed forest, so you can be sure it’s responsibly produced.
Timber is a natural material, it stores carbon as it ages and biodegrades naturally when it’s done. UPVC is plastic based on oil, and aluminium production takes a enormous amount of energy.
If the environmental impact of your home matters to you, timber is the clear option. It’s as simple as that.
Aesthetics and worth
Weight. Depth. Grain. No artificial alternative can copy it.
Sandstone tenement. Light stone villa. Period Scottish cottage. Put timber windows in and they fit. Put UPVC in and it’s always slightly wrong, it just can’t that same fit.
Value, too. On older properties, where original or sympathetic features are part of what makes them special, timber windows contribute genuine value that UPVC never quite does.
Double glazing timber windows
Whether sash or casement, all the windows we manufacture feature double-glazed sealed units fitted. It’s always fitted.
Sealed unit in the frame. Two sheets of glass. Sealed cavity between them. Cuts heat transfer. Improves sound insulation.
Timber frame. Double glazing. Combined: strong thermal and acoustic performance across both window styles.
Traditional divided-light look? We can add glazing bars, a simple addition that makes a real visual difference.
Older frames. Single glazing only. Still solid? We can in many cases upgrade to double glazing as part of a restoration. Existing frames are preserved. Thermal performance improves. No full replacement.
Regular request on Chryston’s older properties. Existing sash windows: solid. Single glazing: lets in cold and road noise.
Every unit we install complies with the latest building regulations governing thermal performance.

Timber windows and conservation areas
Scotland has more than 600 officially recognised conservation areas, and if you’re in one affects what you are permitted to do with your windows.
If your property is in one of these areas, you need to know that UPVC is not an approved window material. Your local council may require replacements that replicate the original in material, design, and profile.
Over 20 years making timber windows for conservation areas and listed buildings across Scotland. We understand 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 depth for anyone who wants to know more.
Wood options
Woodfellas uses two types of timber across its entire window range.
Treated pine is what most customers choose, pressure-treated to ward off rot and decay, takes a paint finish well, and performs in Chryston’s damp climate with no a problem.
For properties where a natural timber look is wanted, or where extra strength is called for, we offer hardwood, which is by nature more immune to damage and takes stains and oils beautifully.
We help you choose the right timber for each project, based on the property, its exposure level, and the finish you need. Just ask and we’ll guide you.
Timber windows, your questions answered
What timber windows do you make?
We produce two main types: sash and case windows and casement windows, both available in treated pine or hardwood. Sash and case are the traditional Chryston style, moving vertically within a box frame. Casement windows are hinged and swing outward. We also produce fixed window panels to match any opening setup.
Is timber better than UPVC?
On performance, longevity, and looks: yes. Timber insulates more effectively at the comparable frame thickness, lasts a lot longer when maintained, and can be restored rather than replaced when damage occurs. It’s also the sole material permitted for listed buildings and is highly favoured in conservation areas.
Can you replace single glazing with double glazing in existing timber windows?
In most cases, yes. If your current timber frames are in sound condition, we can upgrade the glazing to double-glazed sealed units as part of a restoration. That preserves the original frames and look while boosting thermal and acoustic results.
