Woodfellas. Cardonald-based timber window specialists. We make, renovate, and fit timber windows from our Cardonald base, working across homes and business properties right across Central Scotland.
Each window is custom-built using responsibly sourced treated pine or hardwood timber. Double glazing and upgraded security are included as standard on every unit.
Whether you need sash and case windows for a Victorian tenement, casement windows for a contemporary extension, or a complete set of replacement windows for any kind of property, we make them in-house and put them in ourselves.
Our wooden window options
We produce two primary types of timber window, each suited to different properties and requirements. Both are made in treated pine or hardwood, and both come with double-glazed sealed units as standard.
Sash windows
Scotland’s traditional window style.
Sash windows move up and down within a box frame, using a system of weighted cords and pulleys doing the work. They’re the standard window type on most of Cardonald’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.
The best sash windows should look exactly like the original. We renovate, repair, and manufacture custom ones matching original profiles and proportions, while delivering modern thermal and acoustic results where it counts.
Restoration typically includes draught-proofing and double glazing upgrades, and it’s the most sensible option where the original frames are in good condition. We complete full inspections before recommending any replacement.

Standard casement windows
Hinged. Open outward to open. Wider opening, easier access from inside. Typical on Cardonald properties built from the 1920s on, including extensions, dormers, and new builds.
Side hung, top hung, fixed, three configurations, all in custom timber. And like our sash windows, every casement we make is custom-built and double glazed as standard.
For more on options and choices, our timber casement windows page has all the detail you need.
Why timber windows make sense
Timber has been the leading window material for hundreds of years. Not just tradition, it genuinely outperforms UPVC and aluminium in multiple areas that count to homeowners.
Natural heat insulation
Here’s something that trips up people: timber actually carries heat far less easily than aluminium, and it outperforms UPVC at the same frame width. That means the frame itself is already doing more thermal work before you even consider the double glazing.
Scotland’s not exactly warm, and energy costs are no joke, so the fact that timber frames insulate better makes a real difference to what you pay.
Repair, not replace
If a timber window deteriorates, the good news is you can repair it.
Rot in a sill or bottom rail, fresh timber goes in. Damaged frame section, it gets repaired. The story with UPVC is not the same: no repair option, so when it fails, the entire unit ends up in landfill and you’re starting from scratch.
Over a property’s lifespan: repair and maintain, not replace. Cuts cost. Cuts waste.
Sustainability
All timber that goes into our windows is procured from ethically managed forest.
Timber is a natural material, it holds carbon as it ages and biodegrades naturally when it’s done. UPVC is plastic derived from oil, and aluminium production takes a significant amount of power.
If the carbon impact of your house counts to you, timber is the clear choice. It’s as straightforward as that.
Timber windows, character and value
Timber windows have a heft, a character, and a grain that no artificial material can replicate.
Traditional sandstone tenement. Light stone villa. Traditional Scottish cottage. Timber windows look right. UPVC never quite manages.
Timber windows also bring real value to a property, especially period properties where original or sympathetic features constitute part of the property’s appeal.
Double glazed wooden windows
Every window we manufacture, sash or casement, includes double-glazed sealed units installed as standard. Always.
The sealed unit sits within the timber frame and works with two sheets of glass with a cavity. The effect is less heat transfer and improved sound insulation.
The timber frame’s inherent insulating characteristics combined with the double-glazed sealed unit give you solid thermal and acoustic results across both window styles. That’s what you get as standard.
For properties that call for a traditional divided-light look, we can add glazing bars as an addition.
Older frames. Single glazed. Still in good shape? We can often upgrade to double glazing as part of a restoration. Original frames are preserved. Performance gets better. No full replacement.
It happens a lot on Cardonald’s older properties, existing sash windows that are well-built, but the single glazing allows in cold air and street noise like it’s not even there.
Building regulations for thermal standards? Every unit we install meets them. No exceptions.

Timber windows for conservation areas
Scotland contains in excess of 600 recognised conservation areas.
In a conservation area? UPVC is not an approved window material, and your local council will likely require replacements that mirror the original in material, design, and profile.
Over 20 years manufacturing timber windows for conservation areas and listed buildings across Scotland, we know exactly what the council expects.
We help with consent requirements. We make windows that meet planning condition. Modern performance guaranteed. Our sash and case windows page covers the regulations in more depth.
Our timber options
We use two timber types across the entire window range, here’s what you need to know about each.
Treated pine: most chosen choice. Pressure-treated against rot and decay. Accepts a painted finish well. Performs reliably in Cardonald’s damp climate.
Want a natural timber finish or need extra durability? Hardwood is the answer, naturally more immune to damage, and it accepts stains and oils beautifully.
Not sure which timber to choose? We help you choose the right option for each job based on the property, the exposure level, and the finish you have in mind.
Timber windows, frequently asked questions
What types of timber windows do you manufacture?
We make sash and case windows and casement windows, both available in treated pine or hardwood. Sash and case are the traditional Cardonald style, moving vertically within a box frame. Casement windows are hinged and swing out. We also build fixed window panels to suit any opening setup.
Timber windows vs UPVC, which is better?
Three things: results, longevity, looks. Timber wins on all three. More effective insulation at the equivalent frame width. Significantly longer lifespan when maintained. Can be repaired, not replaced. And it’s the sole material accepted for listed buildings, greatly preferred in conservation areas too.
Can you upgrade single glazing to double glazing in existing timber windows?
In many cases, yes. If your current timber frames are in good condition, we can switch the glazing to double-glazed sealed units as part of a restoration programme. The outcome is improved thermal and acoustic performance while retaining the existing frames and appearance.
