MUIRHEAD TOWER

Colt has won the contract to design, manufacture, supply and install a secondary facade of fixed glass louvres as part of the refurbishment works for Muirhead Tower in Birmingham.

The Muirhead Tower was originally completed in 1971 and is a sixteen-storey landmark building owned by the University of Birmingham. The building has suffered from failure of its glazing system and therefore is undergoing a complete refurbishment right back to its concrete frame.

The Colt Shadoglass system will incorporate a system of supporting steelwork and bespoke brackets attached to the existing concrete floor slabs onto which will be attached low iron laminated fixed glass louvres with a bespoke 50% white frit optimised for solar shading and light transmission. The glass louvres will be 320mm wide and up to 3000mm long, with intermediate stainless steel hanger supports. This is an unusual design because of the long louvre spans and the consequent need for special fixing arrangements.

These elements will be installed onto the south facades of two towers that are each 41m high, and the total area of glass louvres will be approximately 1000m².

The purpose of this secondary façade is to act like an additional skin in order to control the solar heat gains and light entry to the building.
