St. Paul's Church in Hatfield Road, St. Albans, which celebrated its centenary in 2010, undertook a major modernisation programme to the church and its adjacent halls. To remain in active use all buildings need to be kept up to modern day standards whether they are private residential, commercial or ecclesiastical. As testament to this the Vicar of St. Paul's, Canon Tony Hurle says: "The new design helps us celebrate the past while giving us first class facilities for use by both the community and the congregation for the next 100 years. A number of environmentally friendly features have been incorporated into the refurbished buildings, including photovoltaic panels on the roof, the use of low energy and sensor lights and an enhanced level of insulation to the existing walls and roofs of the church hall. Additionally, further energy efficiency improvements are achieved with the provision of secondary glazing to the Church Hall." Fourteen complex windows were treated with a total of 46 secondary glazed units, mostly curved hinged or fixed units to match the existing window design. These also provide significant levels of noise insulation, an important consideration to limit the impact of the hall on local residents.
