Ham Yard Hotel is a striking building situated in a lively part of London. Built on a plot, which was unoccupied for years, numerous plans were put forward to develop the site; all were rejected until consent was granted for Firmdale Hotels. Although new double glazed windows were installed throughout, the corner of the hotel still suffered from high external noise levels. The introduction of secondary glazing is one of the most effective solutions for combating noise. A reduction of 45dB is achievable when there is a gap of at least 100mm. A total of 37 openings were treated with secondary glazing finished in a dark grey colour to match the existing primary windows. Acoustic laminated glass was used, which absorbs the outside noise levels. As testament to the detailed planning throughout the design and build phases, their efforts were rewarded with the hotel gaining a BREEAM Excellent rating.Established for fifty years’ Selectaglaze is the specialist in secondary glazing and has extensive experience on working on all building types.
