Fletton Quays – Peterborough

Nov 14, 2018 | Architects & Commercial, Heritage & Listed Buildings, Offices |

As part of a £120 million redevelopment scheme at Fletton Quays, Granada secondary glazing was selected to design, manufacture and install bespoke arched secondary glazing systems to decrease the building’s carbon footprint and heat loss.

Constructed in 1845, the Grade II listed building was used as Peterborough’s first railway station and had been derelict for over 40 years. Renovation of the Victorian railway sheds was a major part of the riverside site’s development to create the city council’s new office, Sand Martin House.

Prevent heat loss

Secondary glazing is an ideal solution to prevent heat loss while preserving a building’s essential character. Double glazed sealed units were specified with the dual purpose of reducing heat loss and noise levels to suit its modern commercial use.

Granada’s arched heritage hinged frames supporting double glazed sealed units were manufactured and installed to achieve an overall U-Value of 0.8W/m2K. This represents a considerable reduction in heat loss as studies have shown that a single glazed metal window has a U-Value of 5.7W/m2K. Decreasing a building’s U-Value will lower energy consumption leading to reduced energy bills.

Due to the building’s Grade II listing, the secondary glazing installation had to be discreet and unobtrusive. To match the style and aesthetics of the primary windows, Granada Glazing’s arched hinged units comprise one glass panel.

Hinged units are popular as they match the sightlines of the primary windows and are undetectable from the exterior of the building. Easy to operate, they offer exceptional acoustic and thermal performance and can be customised to meet most requirements.

Bespoke arching service

Granada Glazing offers a bespoke arching service at its state-of-the-art manufacturing facility where aluminium secondary glazing frames can be shaped to follow even the most challenging of curves.

Granada’s secondary glazing is frequently installed in listed properties, as well as buildings in conservation areas and areas with high noise pollution where it delivers enhanced thermal and acoustic benefits.

When correctly specified and installed, secondary glazing maintains a building’s charm and character while bringing the glazing system firmly into the 21st century.
