Epwin PVC Sliding Sash Windows
Epwin PVC sliding sash windows combine traditional heritage design with modern efficiency. Our PVC sash windows can be specified to replicate the appearance of traditional timber box sash windows, with authentic detailing such as slim meeting rails, deep bottom rails and mechanically jointed frames for a true period look. With smooth sliding operation, excellent thermal performance and minimal maintenance, they are an ideal solution for both period properties and modern homes.
Authentic Detailing
Our premium timber-alternative sash windows are designed to replicate traditional box sash windows. Features such as slim meeting rails, deep bottom rails, run-through sash horns and mechanically jointed frames create a truly authentic heritage appearance.
Smooth Operation
Modern spiral balances allow the sashes to glide smoothly and tilt inwards for easy cleaning from inside the home. Travel restrictors and optional child safety features provide additional peace of mind.
Efficient & Low Maintenance
Unlike traditional timber windows, PVC sash windows require very little maintenance. Multi-chamber profiles, draught-reducing seals and modern glazing provide excellent insulation and long-term durability.
Premium Timber Alternative Option
For customers looking for the most authentic sash window appearance, our timber-alternative PVC sash windows include:
Mechanically jointed frames that replicate timber joinery
Slim meeting rail for traditional sightlines
Deep bottom rail for authentic proportions
Run-through sash horns
Woodgrain finishes such as White Woodgrain, Chartwell Green, Cream and Irish Oak
Georgian bar options
These details allow the window to closely match the look of traditional timber sash windows while benefiting from modern materials.
Standard PVC Sash Option
For more budget-conscious projects, the windows are also available in a standard PVC configuration, offering:
Welded frame joints
Standard meeting rails
Clean white PVC finish
Same smooth sliding functionality
This provides a cost-effective alternative while still delivering the classic sash window style.
