Crittall launches the Berkeley steel window

A window type created initially to replace existing 1920s and 1930s steel windows is equally as acceptable for high-end new build as it is for restoration projects.

The newly developed Berkeley from Crittall Windows provides the architect and designer with minimum sightlines, maximum daylight and fine detail.

Where predominantly single pane leaded glass fenestration is to be replaced and upgraded the Berkeley offers an entirely new series of hot rolled profiles in a window where a solid steel chamfer replicates exterior putty.

Hot-dip galvanized for durability, and in-house Duralife® polyester powder coated for exceptional performance and minimal maintenance, the Berkeley window is available in a wide variety of sizes and configurations to suit any building where strength and security combined with slim and elegant frames are required.

It is a high performance product with a unique articulated frame and sash, accepting glazing up to 18mm. Double integral EPDM weatherstripping is incorporated and sound attenuation for single glass is 20-28 dB, and double glass 28-30dB (approximate values averaged over a frequency range of 100 to 3150Hz).

High-end residential, institutional and commercial applications will be typical outlets for the Berkeley and a recently completed central London project exemplifies one such use.

Douglas House is a luxurious residential new build just off Vincent Square in Pimlico, SW1. The ten two and three-bedroom apartments and a penthouse are located within five floors and Crittall supplied doors and vents together with fixed lights in a contract worth more than £240,000.

The building, which makes a bold statement on a prominent corner site, was designed by Italian architect Marco Vinicio and main contractor was Shepherd Construction.
