Why Westerham Homeowners Choose Our Sliding Sash Windows
Westerham is renowned for its historic architecture and protected conservation zones, meaning off-the-shelf replacement windows are rarely suitable. Our heritage sliding sashes combine authentic period craftsmanship with modern double-glazing technology:
-
Conservation-Friendly Detailing: Built with deep bottom rails, ultra-slim mid-rails, authentic run-through sash horns, and mechanical timber-look joints to satisfy Sevenoaks District Council planning standards.
-
A+ Thermal & Energy Efficiency: Multi-chambered frames, high-performance double glazing, and perimeter brush seals trap heat inside during cold Darent Valley winters—dramatically reducing energy bills.
-
Easy-Clean Tilt Mechanism: Both top and bottom sashes tilt inward smoothly, allowing you to clean external glass easily and safely from inside your home.
-
Multi-Point Security Protection: Outfitted with key-locking sash fasteners, travel restrictors, and toughened safety glass to keep your family completely secure.
-
Low-Maintenance Timber Alternatives: Advanced uPVC and composite sashes deliver realistic woodgrain textures without the rotting, swelling, sticking, or repainting associated with traditional timber.
Frequently Asked Questions
Can uPVC sash windows be installed in Westerham conservation areas?
Yes. Our specialized heritage range features mechanical joints, deep bottom rails, and slim sightlines designed specifically to replicate traditional timber. They are frequently specified for period properties in protected conservation areas across Westerham and the Sevenoaks district.
Will double-glazed sash windows reduce noise pollution?
Yes. The combination of multi-chambered sash profiles, tight perimeter weather seals, and high-performance double glazing creates an effective acoustic barrier—significantly dampening local road traffic noise.
How do I clean upper-floor sliding sash windows?
Our sliding sash windows feature an integrated tilt-in mechanism. Releasing the internal catches allows each sash to tilt inward toward the room, enabling you to clean external glass quickly and safely without using ladders.

"An unbelievable transformation for our Victorian terrace"
"Living near Westerham High Street, we were incredibly protective of our home’s period character but couldn't cope with the freezing drafts from our old wooden sashes. Future Double Glazing installed beautiful timber-alternative uPVC sashes and the result is stunning. They look completely authentic, the house is whisper-quiet and warm, and the tilt-in cleaning feature is brilliant. Phenomenal service!"
