Traditional & Modern Sash Windows for Your Home
At Milton Windows and Doors, our sliding sash windows blend timeless appeal with modern performance. These elegant windows are a classic choice for period properties and character homes — and with contemporary materials and technology, they also suit modern residences looking for an authentic, stylish look.
What Are Sash Windows?
Sliding sash windows are vertically opening windows where one or more framed panels (called sashes) slide up and down within the frame. They offer a traditional aesthetic and versatile ventilation while maintaining a classic architectural style that complements many home designs.

Authentic Traditional Design
Our sash windows are informed by historic craftsmanship but enhanced with modern engineering for durability and performance. Whether you select a classic timber version for heritage properties or a low-maintenance uPVC alternative, the result is a beautiful window that preserves the character of your home.
Timber Sash Windows

- Made from responsibly sourced softwood (European Pine) or hardwood (African Sapele)

uPVC Sash Windows
uPVC sash windows pair the charm of traditional design with the practical benefits of modern materials:
- Minimal upkeep with no need for painting
- Smooth running with spiral balance mechanisms
- Tilt-in sashes for effortless cleaning
- Available in woodgrain finishes that replicate the look of timber without the maintenance
This makes uPVC a smart choice for many properties — especially where classic aesthetics and contemporary convenience meet.
Bespoke Styles & Finishes
Every sash window we make is customised to your specifications. Choose from a wide range of colours, finishes, and combinations that suit your home’s character:
- Single colour frames (same inside and out)
- Dual colour frames (white interior with a matching exterior shade)
- Woodgrain effects that mimic traditional timber
These options let you match windows to both your exterior and interior design.
Functional & Smooth Operation
Sash windows can be made to open from either top or bottom, offering flexible ventilation. Modern mechanisms like spiral balances ensure smooth, effortless movement, while traditional cords and weights are also available for a classic feel. Many designs include built-in restrictors so windows can safely open just enough for airflow without fully swinging open.
Performance & Benefits
Sliding sash windows bring more than style — they deliver practical benefits too:
- Excellent energy efficiency with A-rated double glazing
- Reduced draughts and better insulation
- Low maintenance for uPVC alternatives
- Wide choice of hardware and glazing options (privacy glass, decorative glass, etc.)
The combination of classic design and modern technology ensures you get both traditional looks and dependable performance.
Common Questions About Sash Windows
Can sash windows be double glazed?
Yes — double glazing is a standard option that enhances thermal performance and reduces noise, ideal for both period and modern homes.
What makes sash windows different to casement windows?
Sash windows slide vertically, while casement windows open outwards like a door. Both have their advantages, but sash windows stand out for traditional style and heritage appeal.
Can I switch sash windows for another style?
Swapping sash windows for another type — like casement — may require planning permission, especially in conservation areas or listed properties. Always check local regulations first.
