Sternfenster now offers its new Alitherm 400 aluminium casement window in a flush finish, which brings a sleek and contemporary look to any property, such as high-end domestic refurbishments, or light commercial projects.

The Alitherm 400 flush casement sits flush within the frame, and provides a clean and streamlined appearance, in keeping with modern trends.

“When we launched the Alitherm 400 at the start of 2024, it was a continuation of our trend of meeting and exceeding customer demand,” Sternfenster’s Sales Director Nathan Court said. “It has slim sightlines, it is high performing, and it is quick and easy to install.

“By launching a flush version of the Alitherm 400, we are supporting our customers as they target the high end of the refurbishment market specifically, where the demand for a sleek flush finish is at its highest.”

Sternfenster’s Alitherm 400 flush casement window achieves a Window Energy Rating of A with a double-glazed unit, making it fully compliant with Building Regulations for refurbishment projects.

It can also achieve a U-value of 1.2W/m2K with a triple glazed unit (with a centre-pane U-value of 0.8W/m2K), making it ideal for newbuild properties.

The 70mm thermally broken aluminium window also boasts leading weather performance, successfully passing: BS EN 1026 (air permeability); BS EN 1027 (water tightness); BS EN 12211 (wind resistance); and can meet PAS24 or Secured By Design requirements thanks to optional sash claw locks.

The new Alitherm 400 window comes with Sternfenster’s new QUICKglaze knock-in glazing bead with co-extruded gaskets, which helps reduce time spent on site because less time is spent hunting for parts, and installation is very swift – potentially shaving hours off a job.

The Alitherm 400 casement window comes with additional features that help meet the many demands homeowners place on new windows. These include dual colour options, trickle vents, triple glazing up to 38.8mm, and mega egress hinges if the window needs to offer a fire escape route.

“The Alitherm 400 window offers flexibility across a range of projects, meeting multiple demands,” Nathan said. “Thanks to features like dual colour, PAS24/Secured By Design compliance, and now the flush sash option, we are helping to create profitable opportunities for our customers.

“And we support our customers by giving them full visibility of the production process via Sternfenster-Plus (SF+) and EasyAdmin.”

EasyAdmin allows businesses to produce professional quotes very quickly for homeowners. It also allows window installation companies to have complete oversight of their profit and loss. This information is updated daily and allows business owners to see the health of their accounts in real time.

EasyAdmin works with SF+, which improves communication with customers and gives them greater insight into the fabricator’s manufacturing capacity.

The new Alitherm 400 casement window is available now from Sternfenster in lead times as short as five days.
