What gives flush sash windows their enduring appeal?

Flush sash windows have long been popular in traditional buildings and have more recently emerged as a stylish choice for contemporary homes too. 

Now celebrating its 25th year of trading, Pearl Window Systems launched a dedicated new-build division in 2023, but also has considerable experience of manufacturing fenestration solutions for heritage property restorations. 

CEO Jeff Walsh shares his thoughts on recommending Liniar’s flush sash Resurgence window system for both modern and period properties.

Prestigious, modern homes 

Shortly after launching its new-build division, Pearl was approached by Northstone Homes, a developer with a reputation for forward-thinking design. 

Jeff explains, “Northstone were considering a change to PVCu windows on all their projects, and looking for a product that not only met their high aesthetic and quality standards but offered market leading technical performance as well.

“Northstone’s design approach incorporates high ceilings, open-plan interiors, and floor-to-ceiling windows to create bright, naturally illuminated spaces. 

“I recommended Liniar’s Resurgence system, knowing that the flush finish would give each property a sleek, stylish façade while delivering the exceptional thermal, acoustic and weather performance the project specified” he continues.

“Resurgence is a double-rebated system (the UK’s first) which means it achieves a superior seal between the sash and the frame. This innovative design, combined with the PVCu profile’s multi-chambered insulative properties, maximises thermal efficiency and weather protection.” 

Pearl Window Systems is now working in full partnership with Northstone Homes on five sites across the Northwest - Popple, Horwich, Glisk, Tulach and Keld. 

Liniar’s Resurgence flush sash system has been exceptionally well received, with Northstone Construction Director Rob Rudkin commenting, “Resurgence complements our contemporary, award-winning architecture whilst also meeting the high thermal and acoustic performance we require, which sits above current industry standard.” 

Chameleon-like characteristics. 

Fenestration choices can be used to make bold statements about the character of a building and its occupants, but it may equally be necessary to blend in with wider surroundings without upsetting the apple cart.

Jeff tells us, “A clear benefit of flush sash windows is the ability to seamlessly integrate with their environment, delivering an unobtrusive finish. For example, when replacing windows in buildings with historic significance or in rural settings, there can be heightened potential for style and material choices to come under scrutiny from Local Planning Authorities or concerned residents in the local community.

“In such circumstances the Resurgence system’s ability to closely imitate the appearance of traditional timber is highly beneficial and can appease concerns. Resurgence windows can be manufactured with either Timberweld, mechanical or welded joints depending how closely it’s necessary to imitate classic wooden windows. 

Combined with the through foiling finish, which means no bare PVCu is visible even when open, the overall appearance of Resurgence is well suited to preserving the integrity of older buildings.”

Cutting-edge versatility

On the enduring appeal of flush sash windows, Jeff concludes, “My experience working with the Resurgence system demonstrates exceptional versatility and highlights the timeless attractiveness of flush sash windows. 

“Through an ability to closely replicate traditional timber and to offer a minimalist, stylish touch with all the performance benefits of state-of-the-art PVCu window technology, it’s not difficult to see how flush sashes have become such a popular choice - a trend I expect to see continue.”
