The Sashless Windows Factory

About Us

Sashless Windows is a British manufacturing company producing high quality, factory finished, timber window and door sets offering unrivalled value for money in our market sector.

Established in 1965, the company introduced a unique and innovative window design into the UK from the cold climes of Canada, where a 'dual glazed' window without sashes (hence: 'sash-less') was being widely used. The 'Quebec' offered a cost effective form of double glazing, providing large areas of glass for improved light transmission in the gloomy winters of 1960's Britain.

An instant success with Local Authorities and Private Developers alike, the Quebec and Yorklite window range formed the back bone of the business for over 15 years, establishing the company's long standing relationship with Architects and specifiers where we still offer a design and specification service.

With the improvement in double glazing sealed unit technology, the 1980's saw Sashless introduce a comprehensive range of double glazed Flush Casement and Stormproof window systems.

Over the years the range has been improved and extended to include the Richmond Vertical Sliding (Box Sash) window range, statement piece front doors, external front and rear door sets, bi-folding doors, double rebated French doors, lift and slide Patio doors, curtain walling and feature glazed screens.

Sashless also offer a limited 'Installation Service' for a complete supply and fit package.

With over 50 years' experience of manufacturing timber windows our comprehensive 30 year window warranty actually means something, and of course an Insurance backed warranty is available for our supply and install packages.

Today, Sashless are still the same family owned and family run business that we were back in 1965 but we have evolved and grown to become a volume manufacturer of bespoke window and door systems manufacturing all of our products at our Northallerton factory, delivering nationally across Britain to our diverse range of customers.

Primarily a Business to Business operation, Sashless supply windows and doors to High End luxury housebuilders and developers, to Public Sector refurbishment schemes, to the Education & Health Care Sector and to clients who demand the best.
