A Lesson in Light Working on school projects takes a little more thought and preparation than in any other roof glazing contract because there are more considerations to plan for in advance. These include having company enhanced dbs clearance for all site employees from installer to foreman and project manager. Installations need to be sensitive to the time constraints of schools too, with deliveries scheduled to arrive after peak times when children are not approaching or leaving school. Congestion around schools would make for a challenging approach to site and unloading at this time could be a safeguarding nightmare. Howells Patent Glazing have been experts in bringing ascetically pleasing natural light glazed roofs to educational facilities, such as schools, colleges and universities. Leeds City College had a particular problem of 40 year old patent glazing system with single glazing. It had been constructed using steel bars, which were not thermally efficient, leading to daily heat loss and condensation build up because no ventilation was included. We attended the site and supplied new aluminium thermally enhanced patent glazing, using our HG3 profile. Although at the time we could not remove the asbestos ourselves and had to arrange via the main contractor, we now have certification to do this aspect ourselves. We installed the new double glazing, but also used energy enhanced glass on the inner pane which had a thermal coating. This helped to keep the heat in the room and was provided from a well known manufacturer of glass, Pilkington, using their K range thermes 1. To help with the air circulation problem, we also installed 30 electrically operated opening lights, which were in addition linked to the building management system. Bourton Meadow School in Buckingham, was another challenge because the original double glazed roof was leaking badly and the ridge had dropped and was wavy. There was also a problem with retained heat, making it too hot to work in, as there was no ventilation or air flow at all. We supplied our fully thermally broken double glazed mono pitch Rooflight system. To tackle the heat and ventilation issues, we installed a vent in every other pane, these included rain censors and thermostatic controls. In the 40 classrooms we included a separate control panel to allow thermal management in each room. Mono pitch rooflight System Bourton Meadow To keep the thermal properties of the glass, we also provided high performance solar controlled glazing with Glassolutions (ex Saint-Gobain) COOL-LITE range SKN174. As well as school fittings, we also work on public sector projects, including nursing homes and hospitals, commercial, retail, leisure and private homes. Our product range comprises of Rooflights bespoke, mono, gable ended and hip, lantern, frameless flat lights, north lights, mono and double pitched roofs.
