Authentic style meets conservation compliance
Replacing windows in a conservation area presents a unique challenge: how to maintain architectural authenticity while upgrading to modern performance standards. At Fairco, we’ve developed the ultimate solution—Heritage Sash windows for conservation areas.
Crafted to replicate the exact appearance of traditional timber sash windows, Fairco Heritage Sash windows offer period-correct proportions, sightlines, and features—while delivering A-rated energy efficiency, noise insulation, and long-term durability.
If you live in a protected area and want a window that meets planning requirements without sacrificing comfort or aesthetics, Heritage Sash windows for conservation areas are your ideal upgrade.
What are conservation areas in Ireland?
Conservation areas are designated zones of architectural or historical importance protected under Irish planning law. From Georgian terraces in Dublin to Victorian streetscapes in Cork and Limerick, these areas preserve the charm of Ireland’s built heritage.
When it comes to replacing windows in these areas, local authorities often require “like-for-like” replacements—meaning the new windows must replicate the materials, proportions, and profiles of the originals.
That’s why uPVC casement or modern flush windows won’t cut it—but Fairco’s Heritage Sash will.
Heritage Sash craftsmanship that’s built to match timber
Precision-made for authenticity
Fairco’s Heritage Sash windows go far beyond standard sash replacements. They are meticulously crafted with the finest attention to detail, making them one of the most accurate timber sash replications available in Ireland.
Our design includes:
- True end-sealed mechanical joints, created using traditional butt-joint methods (horizontal on the frame, vertical on the sashes)
- An ultra-slim 35mm meeting rail, thinner than most on the market, replicating the appearance of a single solid piece of timber
- Seamless run-through horns, with no cap or visible shadow line—perfect for Edwardian and Victorian aesthetics
- Optional Seahorse sash horns, a classic curved detail used in 19th-century joinery to showcase craftsmanship
- Optional horn-free finishes for Georgian-style properties
This level of detail gives our Heritage Sash windows for conservation areas unmatched authenticity – often passing the toughest planning inspections.
Heritage aesthetics with modern benefits.
While our Heritage Sash looks like a 19th-century timber window, it performs like a modern one. Here’s how:
A-Rated energy efficiency
Thanks to advanced multi-chambered uPVC frames and double glazing as standard, these windows are A-rated for thermal performance. You’ll enjoy a warmer home, lower energy bills, and significantly better insulation than single-glazed timber windows.
Outstanding noise reduction
Ideal for busy cities or roadside homes, our Heritage Sash windows block out unwanted noise, helping create a quieter, more peaceful environment indoors.
Built for the Irish weather
Designed to resist wind, rain, and moisture, Fairco’s sash windows won’t rot, warp or swell like timber. That means long-term durability and less maintenance – without compromising on looks.
Custom-fit colour & style options
Fairco’s Heritage Sash comes in 10 period-correct colours, all available with natural woodgrain finishes to complete the timber look. From soft cream and chalky whites to Irish oak and heritage grey, your new windows will feel truly at home.
We also offer deep cills, staff beads, and chalk finishes, further enhancing your home’s architectural harmony.
