Formerly known as the Ramada Hatfield, the Comet’s multimillion pound refurbishment which began in 2017 is now complete.  The works were entrusted with contractor ISG Bristol and designed by architects Stride Treglown. The hotel had retained the building’s original crittal sash windows but this did not provide the required level of noise insulation to a number of the guestrooms, restaurant and function spaces for meetings and networking events. Selectaglaze installed 104 secondary glazed units, with a cavity between the existing primary windows and the secondary units to significantly improve the level of noise insulation. The secondary windows were made bespoke to ensure the best fit and included four different systems, tailoring the units specifically to the project’s needs. The Series 20 vertical sliding units were faceted onto the curved on plan original bay windows on the ground and first floors. The Function room was fitted with the Series 15 three-pane horizontal slider, which can support thicker glass when higher levels of noise insulation are needed. The majority of openings in the hotel guestrooms were treated with the Series 10 horizontal sliding unit, which is a versatile system that provides easy access to the outer window. In addition, four of the smaller windows on the first floor were treated with Series 45 side hung casements, with no new sight lines making it very suited to the hotel’s Listed status.
