Once on the Historic England’s unsafe register, the Grade II Listed Lighthouse building has been sensitively renovated into a warm and peaceful office and retail space with the support of Selectaglaze.
Adjacent to Kings Cross, sits the iconic Flat-Iron Lighthouse building. Records on when it was built are lost, but indications are that it was between 1875 and 1884.
Having lain derelict for over 20 years, UK Real Estate took on the challenge of revitalising the Lighthouse building into office and retail space and appointed Balfour Beatty as its main contractor. With two underground tunnels running underneath; the building’s restoration had to be carefully managed, confronting the issues of noise and vibrations.
The solution was to isolate all internal fixtures and fittings by inserting elastomeric bearing pads at all points of contact with the external structure. Secondary glazing was essential to this solution. As an independent internal window system, it allows the full sealing of the internal envelope.
Selectaglaze is the leading expert in the design, manufacture and installation of secondary glazing, working on a variety of building types. Selectaglaze recommended 8mm toughened glass, glazed to Series 25 and Series 90 vertical sliders and Series 41 lift out units, suiting the style and sightlines of the primary window. Selectaglaze installed a total of 83 bespoke units.
When there is a cavity of at least 100mm between the primary and secondary glazing a reduction of 45dB is attainable. Furthermore, with the use of high performance twin seals, it eradicates unwanted drafts and a U-value of 1.8 is possible.
Selectaglaze units are fully reversible, so most heritage bodies accept it’s use on Listed buildings.
Established in 1966 and Royal Warrant Holder since 2004, Selectaglaze is the leading designer, manufacturer and installer of secondary glazing.More
