Get answers to common questions about our wooden sash windows, from their customisation and installation to maintenance and heritage compliance.
Wooden sash windows offer a timeless aesthetic, exceptional build quality, and the ability to meet conservation and heritage requirements. They also provide excellent thermal and acoustic performance.
Regular cleaning with non-abrasive materials, lubrication of hardware, and application of specified maintenance products will ensure long-lasting performance and appearance.

Replacement sliding sash windows generally require local authority approval to ensure they match the property’s original style.

In most listed buildings, traditional appearance is essential. Lomax + Wood provide single-glazed timber sash windows with traditional putty glazing where required, while also offering double-glazed sash windows for permitted projects, ensuring both heritage authenticity and improved energy efficiency.
We use high-quality, sustainably sourced timber to ensure our sash windows are durable, eco-friendly, and beautifully crafted for long-lasting performance.
