New Box Sashes

Bespoke Manufacturing: Traditional Box Sashes Built to Last

When original windows have suffered irreparable structural failure or have been previously replaced with unsympathetic modern units, our new box sashes provide the perfect solution. We manufacture every unit in our Manchester workshop, combining time-honoured joinery techniques with modern precision to create windows that look historical but perform to 21st-century standards.

Our new box sashes are crafted from sustainably sourced timber, chosen for its durability and resistance to warping. We take great care to replicate the exact architectural details of your property, including specific horn designs, glazing bars, and meeting rail profiles. This attention to detail is vital for homes in conservation areas or for owners who refuse to compromise on authenticity.

We offer two primary mechanical options for our new builds:

  • Traditional Weights and Pulleys: The authentic choice for heritage purists, using lead weights housed within the box frame.
  • Spiral Balances: A modern alternative that allows for a slimmer frame profile, ideal for certain types of masonry openings or specific budget requirements.

Every window is factory-primed or fully finished to your specification, ensuring it arrives on-site ready to withstand the British weather. Whether you are a homeowner looking for a complete replacement or a trade partner needing a reliable supply of high-spec units, our new box sashes represent the pinnacle of British timber manufacturing.
