Euroview Architectural Glass supplied Sealtite Windows with Guardian Climaguard A.1 glass for their project, the former Sydenham Police Station, which is now residential flats. Guardian ClimaGuard A.1 is a thermal insulating glass for double and triple glazed units. It has the highest performance requirements for transparency and solar heat gain as well as Low-E quality to maintain the same thermal performance but with an increased level of solar heat gain. This results in reduced heating costs during winter as well as improved comfort levels.
