Modern Timber Sliding Sash Windows

Modern Timber Sliding Sash Windows

Our modern timber sliding sash windows combine the elegant appearance of traditional sash joinery with the comfort, efficiency and practicality expected from contemporary window systems. Manufactured to order in our UK workshop, these bespoke sash windows are designed to retain classic proportions and authentic detailing whilst incorporating modern glazing technology and improved thermal performance.

Ideal for extensions, renovations, self-build projects and period-style new-build homes, our modern sash windows offer clean sightlines, smooth sliding operation and excellent weather performance whilst maintaining the timeless character associated with traditional timber sash windows. We can also incorporate our discreet hidden vent system, providing background ventilation without compromising the appearance of the window or interrupting traditional sightlines.

Traditional Character with Contemporary Engineering

Traditional Character with Contemporary Engineering

Every modern sliding sash window is handcrafted using premium timber, precision joinery techniques and high-performance glazing systems designed for long-term durability and everyday reliability in demanding UK conditions. Developed to accommodate modern insulated glazing units, this sash system provides improved thermal efficiency and reduced heat loss whilst preserving the balanced proportions and refined detailing associated with classic timber sash windows.

Available options include cords and weights or spiral balance operating systems, bespoke glazing bar layouts, acoustic and safety glazing, factory-applied paint or stain finishes and a wide range of traditional or contemporary hardware styles. We can also manufacture fully customised sash windows tailored to your exact project requirements, including decorative detailing, shaped frames and heritage-inspired configurations suitable for both modern and traditional properties.
