Authentic traditional sash windows for period and new build homes, combining classic detail with modern warmth, security and quiet.
The Right Timber Window for Every Project
From traditional timber sash windows to heritage and flush casement designs, our premium timber windows are crafted to meet the specific needs of period properties, conservation areas, and contemporary homes alike.
Modern Performance Rooted in Traditional Craftsmanship
Modern timber windows have come a long way. Today’s premium timber windows offer superior insulation, excellent energy efficiency, and thermal performance that stands the test of time – without sacrificing the natural grain and visual appeal that make timber the preferred choice for design-led projects.
Whether you are specifying new windows for a listed building or a contemporary self-build, timber frames offer a warmth and character that no other material can replicate. Combined with double or triple glazing options, they represent an ideal choice for clients who refuse to compromise on either aesthetics or performance.
Timber Windows That Meet the Highest Standards
Our timber window range has been developed with architects, specifiers, and self-builders in mind. Each product is engineered to deliver excellent energy efficiency, low maintenance requirements, and long-term durability – making them an excellent choice for projects where the initial investment must be justified by lasting quality.
We understand that environmental impact is a crucial factor in modern specification. That is why our timber windows are manufactured using responsibly sourced materials, certified to FSC standards, and finished with water-based micro-porous coatings. The aesthetic appeal of timber, paired with our technical expertise, makes every window a sound and informed decision.
