Woodfellas. Port Glasgow-based timber window specialists. We manufacture, restore, and put in timber windows from our Port Glasgow base, serving homes and commercial properties throughout Central Scotland.
Not a single window we produce without being built to order. Responsibly sourced treated pine or hardwood, double glazing, and improved security, all standard.
Tenement, extension, any property. Sash and case, casement, or a complete replacement set: we build ourselves and put them in ourselves.
Our timber window range
Two types of timber window. Each built for different properties and specifications. Both available in treated pine or hardwood. Both featuring double-glazed sealed units as standard.
Classic sash windows
The traditional Scottish window, and it has never changed.
Before UPVC, before aluminium, Port Glasgow’s Victorian and Edwardian tenements were built with sash windows, sliding up and down in a timber box frame on weighted cords and pulleys. They’re still the required replacement for listed buildings and conservation area properties where sash and case was the original design.
We refurbish, repair, and make custom sash windows that match period profiles and proportions while delivering modern thermal and acoustic performance.
Restoration usually includes draught-proofing and double glazing upgrades. Most sensible option where original frames are in good condition. We survey fully before recommending replacement.
Casement windows
The hinged window. Swings outward, lets in more air, easy to reach from inside without leaning out. Casement windows became the norm on Port Glasgow properties 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.
Our timber casement windows page has more detail on all available options and choices.
Why timber is the right choice for windows
There’s a good reason people have been installing timber windows in properties for generations, and it’s not just because they always have. Timber truly outperforms UPVC and aluminium in several areas that matter to homeowners.
Timber’s insulating properties
The frame matters, not just the glass. Timber transfers heat far less readily than aluminium and outperforms UPVC at the comparable frame width, giving stronger thermal efficiency from the frame itself, before the double glazing even gets involved.
In a climate like Scotland, where heating costs are a real challenge for most households, the insulating properties of a timber frame make a tangible impact.
Repair, don’t replace
Where deterioration develops in a timber window, remediation remains a practical choice.
Rot in a sill can be taken out and fresh timber put in. A damaged section of frame can be replaced in section. UPVC can’t be repaired in the same way. When it breaks down, the whole unit goes to landfill and you start again.
Think about it: over the lifetime of a property, being able to repair and maintain timber windows rather than replacing them cuts serious money and cuts a lot of waste.
Timber and the environment
The timber we work with is procured from responsibly managed forest, every bit of it.
Timber is a renewable material that holds carbon throughout its working life and breaks down naturally at end of life. UPVC is a plastic derived from oil, and aluminium manufacturing is extremely energy-intensive, worth knowing if the environment is important to you.
If the environmental side matters to you the carbon footprint of your home, timber is the obvious choice.
Aesthetics and worth
There’s a substance, a character, and a natural grain to timber windows that artificial materials simply can’t match.
On a traditional sandstone tenement, a pale stone villa, or a period Scottish cottage, timber windows achieve an aesthetic rightness that UPVC consistently fails to replicate.
Value, too. On older properties, where period features are part of what makes them special, timber windows bring tangible value that UPVC can’t match.
Double-glazed timber windows
Sash or casement, it doesn’t matter. Every window that we make includes double-glazed sealed units installed as standard. Always has been.
The sealed unit fits within the timber frame and works with two sheets of glass separated by a cavity. The result is less heat transfer and better sound insulation.
The timber frame’s natural thermal qualities combined with the double-glazed sealed unit deliver solid thermal and acoustic results across both window types. That’s what you get as standard.
Traditional divided-light appearance? We can fit glazing bars, a simple addition that makes a big difference.
If your older timber windows are still in good condition but single glazed, we can in many cases switch them to double glazing as part of a restoration. This keeps the original frames and improves thermal performance without a full replacement.
This is a frequent job on Port Glasgow’s older properties. The original sash windows are well-constructed, but the single glazing allows in cold air and ambient noise, and upgrading to double glazing solves both.
Every unit we fit satisfies current building regulations governing thermal standards.
Timber windows for conservation areas
Scotland has over 600 officially recognised conservation areas.
Property in a conservation area? UPVC: not acceptable. Council will often require replacements replicating the original. Material, design, profile.
We’ve been producing timber windows for conservation area and listed building properties throughout Scotland for over 20 years. We understand what the council requires, so you don’t have to work it out yourself.
We walk you through consent requirements. We build windows that satisfy planning condition. Modern standards included. Our sash and case windows page covers the regulations in more detail.
Timber choices
Across all our window products, we stock two types of timber.
Treated pine is the most chosen option, and for good reasons. It’s pressure-treated to resist rot and decay, holds a paint finish well, and works reliably in Port Glasgow’s rain-heavy climate.
Want a natural timber finish or need extra hardwearing performance? Hardwood is what you need, naturally more immune to damage, and it accepts stains and oils beautifully.
We recommend the right timber for each project, based on the property, its exposure, and the finish you need. Just let us know and we’ll steer you right.
FAQ, timber windows
What types of timber windows do you produce?
We make sash and case windows and casement windows, both available in treated pine or hardwood. Sash and case are the traditional Port Glasgow design, moving vertically within a box frame. Casement windows open outward. We also make fixed window panels for any opening setup.
Timber or UPVC, which is the better window?
For performance, lifespan, and appearance? Yes, timber wins. It insulates more effectively at the same frame width, lasts a lot longer when maintained, and can be repaired not replaced. It’s also the sole material permitted for listed buildings and highly favoured in conservation areas.
Can existing timber windows be upgraded to double glazing?
In most cases, yes! If your current frames are in solid condition, we can convert to double-glazed sealed units as part of a restoration programme, keeping the existing frames and appearance while boosting thermal and acoustic results.
