Sternfenster has launched its new Alitherm 400 casement window. When double glazed, it achieves a Window Energy Rating of A, 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 ideal for newbuild properties.

The 70mm thermally broken aluminium window also boasts 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.

Price and lead times

Sternfenster’s sales director Nathan Court says: “Importantly, we applied modern PVC-U fabrication techniques to aluminium window production, giving our customers access to a valuable market at a competitive price point and far shorter lead times than traditional alternatives.

“Partnering with Smarts to manufacture the Alitherm 300 window was a key part of this strategy. The new Alitherm 400 window continues our journey of creating new opportunities for window retail businesses.”

Glazing bead

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 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,” adds Court. “But the final sale often comes down to individual choice and that is where our new window shines.”
