Thermally efficient aluminium casement window from Sternfenster

Sternfenster has launched its new Alitherm 400 casement window, which achieves a Window Energy Rating of A with a double-glazed unit, making it fully compliant with Building Regulations for refurbishment projects.

The Alitherm 400 can 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 suitable for newbuild properties.

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

The Alitherm 400 window is available in lead times as short as five days.

“Since 2017, when we invested in our new aluminium facility in Lincoln, we have been a leading fabricator of aluminium windows and doors,” Sternfenster’s Sales Director Nathan Court said. “Importantly, we applied modern PVC-U fabrication techniques to aluminium window production, giving our customers access to a valuable market, but at a competitive price point and far shorter lead times than traditional alternatives. Partnering with Smarts to manufacture their Alitherm 300 window was a key part of this strategy, and the new Alitherm 400 window continues our journey of creating new opportunities for window retail businesses.”

The 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 was designed to be a modern standard window that will appeal to most homeowners in most situations, offering profitable opportunities for window companies in the process,” Nathan said. “But the final sale often comes down to individual choice, and that is where our new window shines.

“Top of this list are the flash sash option, PAS24/Secured By Design compliance and dual colour. These are comfortably met by the Alitherm 400, making it the ideal aluminium window option for window companies to have in their portfolio. And we support our customers by giving them full visibility of the 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.
