Lanchester Building


The Lanchester Building is an award-winning installation which has been completely transformed into a two-form entry primary school and nursery for West Herts Community Free School Trust and is now home to the Lanchester Community Free School. The Windows and doors featured in the refurbishment of the Art Deco-style building is from Smart Systems Alitherm Heritage range and had to replicate the original steel style previously installed, this is due to the building being locally listed both to its historical and its architectural significance.

The installation consists of over 70 window assemblies (covering approximately 650m² in total) and 15 door entrances. The Alitherm Heritage system used emulates the slim sight lines of that system but incorporates modern thermal insulation values incorporating double glazing into slim aluminium sections, whilst still retaining the required strengths for even large windows and doors as seen in the accompanying photographs.
