Derelict market buildings in the central London Conservation Area of Smithfield have been converted to create a warmer, quieter and more secure environment to house the new Museum of London, with the help of secondary glazing from Granada Glazing added to existing timber framed windows.
Working with the main contractors Rooff Ltd, Granada’s technical team devised the optimum secondary glazing solution to solve the key issues of external noise intrusion and preserving warmth in the large interior exhibition areas that are flooded with natural light.
The team installed 30 secondary glazing units, including some substantial Horizontal and Vertical Sliders and Arched units that follow the shape of the primary windows. A mix of 6mm toughened glass panels and 6.4mm laminated safety glass panels were specified to satisfy the required thermal, safety and security secondary glazing requirements.
Slimline aluminium frames, in a white powder coated finish, were installed in ground and first-floor exhibition and office spaces that deliver ease of ventilation and access for cleaning and maintenance for the building’s occupants.
Granada Glazing commercial director Mike Latham said: “Lowering the carbon footprint of public buildings is at the forefront of current thinking, and a particular concern for owners who wish to improve thermal efficiency in Listed properties that must retain their original single glazed windows under planning regulations.
“Installation of secondary glazing is a cost-effective, highly-efficient and discreet solution that brings original primary windows up to modern-day insulation standards, while retaining the building’s character.”
