The rejuvenation of 125 Old Broad Street, better known as the Stock Exchange Tower, has turned an old building into a striking new landmark on the London skyline. The 26 storey tower in the heart of London was refurbished in July 2008. Designed by GMW Architects, the refurbishment saw a complete gutting out of the interior with all of the original services and the cladding systems removed and replaced with a new high performance glazed façade. The building design was merited with a BREEAM “Very Good” award, as the 319,736 sq ft of A class office space was considerate of the occupiers needs, providing floor to ceiling glazing which allows much improved natural light and panoramic views around central London. The overall refurbishment was designed to take into account the BREEAM criteria by making the refurbished building as sustainable and environmental as possible, whilst also producing a working environment that is both productive and comfortable.
Despite working on the original specification for the new façade, the final glass selection was secured by one of Guardian’s competitors. However in 2009, parties involved in the building refurbishment made the decision to re-glaze the entire project. At this point Guardian were fortunate to be selected for the glass replacement with the original specification for heat treated glass on the outer pane, replaced with SunGuard High Selective SN 62/34 coated onto annealed laminate glass surface 2. Now 16,000m2 of Guardian SunGuard High Selective SN 62/34 LamiGlass covers the Stock Exchange Tower, ensuring exceptional energy efficiency combined with unspoiled views out of the building over London.
