Sternfenster has expanded its portfolio with the launch of its PVC-U Regency vertical slider; a next-generation sash window that combines timeless aesthetics with modern performance.

Designed to replicate the classic charm of traditional timber sash windows, the Regency vertical slider is available in three distinctive finishes: Standard Regency, Smoothline, and Timberline.

Each option delivers a different take on heritage styling – from seamless welds to mechanically jointed profiles – ensuring homeowners and specifiers can achieve the perfect look for period properties or contemporary projects.

“Installers are increasingly looking for products that not only meet high technical standards but also deliver real kerb appeal”, said Nathan Court, Sternfenster’s chief sales officer. “With the Regency vertical slider, we’ve combined traditional styling with the very latest in energy efficiency and security, giving them a product that homeowners will love.”

The system has been developed to offer installers and end-users a highly versatile solution. With widths ranging from 460mm to 1,500mm, and heights up to 2,500mm, the Slider provides flexibility for a wide range of applications.

Decorative features such as run-through horns, Georgian bars, and deep bottom rails can be specified, while an extensive palette of colour and hardware options allows for complete customisation.

Performance has also been a priority. The Slider can be manufactured as A-rated, even with laminated glass, and inward tilt restrictors and pre-tension spiral balances make operation safe and simple. Meanwhile PAS24 certification can be achieved through features such as SBD chimneys and sash through-bolts.

“The Regency vertical slider has been designed to give installers a product that delivers on every level – authenticity in design, outstanding thermal efficiency, and modern security,” added Nathan. “It’s about giving our customers a window that’s as practical as it is beautiful, while opening up new sales opportunities in the heritage and premium sectors.”
