Timber Sash Windows

Sash Windows: Blending Heritage Charm with Modern Performance

Our range of timber Sash Windows from Timber Windows perfectly captures the timeless elegance of traditional design while incorporating cutting-edge engineering and modern security. They are the ideal choice for period properties and new homes seeking an authentic, high-performance window solution.

🏛️ Authentic Design & Functionality

We offer two distinct mechanisms, ensuring an authentic look with flawless, easy operation:

• Traditional Box Sash: True to heritage design, the sashes are hung on waxed natural cotton cords or decorative chains (visible within the frame) and counterbalanced by lead weights. This ensures smooth, effortless operation and retains the classic aesthetic.

• Hidden Spring Balance Sash: This modern mechanism uses discreet hidden springs within the jamb, offering the smooth operation of a traditional sash but without visible cords or chains, providing a cleaner, contemporary look.

🌳 Engineered for Stability and Longevity

Just like our casements, our sash windows are built using superior engineered timber for unmatched durability.

• Multi-Layer Engineered Timber: The frames and sashes are constructed using laminated sections of wood with the grain running in opposing directions. This patented technique eliminates the risk of warping, twisting, or sticking often associated with traditional solid timber sash windows.

• Timber Options: Manufactured in robust, knot-free Engineered European Redwood or durable Engineered Meranti Hardwood.

• Durable Finish: A factory-applied, micro-porous paint or stain coating ensures protection from moisture, UV rays, and guarantees a beautiful, low-maintenance finish for years.

🌡️ Thermal Performance & Security

Our sash windows are designed to outperform traditional windows in every critical area.

• Superior Thermal Efficiency: Fitted with high-specification double-glazed units, featuring argon gas filling and warm edge spacer bars. This achieves an extremely low U-value, significantly reducing heat loss and keeping your home warm and quiet.

• Airtight Sealing: We incorporate effective brush pile and weather seals to eliminate draughts and prevent rattling, a common issue with older sash designs.

• Advanced Security:

  • Fitted with security locks and sash stops to prevent the window from being opened beyond a safe ventilation gap.

  • Internal Beading ensures the glass cannot be removed from the outside.

🎨 Customisation and Detail

Each sash window is made bespoke to your specific size and style requirements.

• Glazing Details: Customise your look with a range of options, including astragal bars (offering the appearance of individual panes) or authentic lead detailing.

• Ironmongery: Choose from a refined collection of high-quality sash fasteners, lifts, and pulls in finishes like polished chrome, brass, or satin nickel to perfect the period aesthetic.

• Colour Options: Available in any RAL colour and a selection of curated heritage tones, with the option to specify different colours for the interior and exterior frames.

Our sash windows provide the perfect balance of period authenticity, industry-leading performance, and lasting value.
