Nestling in the beautiful Oxfordshire countryside, sections of this magnificent three-storey Grade II* Listed building date back to the 16th century. The house, its grounds and numerous outbuildings, has been a family home for the past 42 years. With spiralling fuel costs, the owners felt the time had come to investigate ways of providing a warm and draught free home. Serious consideration was, therefore, given to thermally insulating the windows. A total of forty-seven sash and casement windows needed to be treated, many with existing wooden shutters which were to be retained. It was also essential that the windows remained fully operational to facilitate cleaning and maintenance, without introducing additional sightlines. Several rooms feature 17th and 18th century oak and ash panelling with window frames painted to match. To blend imperceptibly with this internal decor, Selectaglaze supplied secondary glazing finished in a brown polyester powder paint. All units were glazed with 4mm toughened low emissivity glass to provide the very best thermal insulation.
