Triple glazing can reduce heat loss by a much greater amount and is therefore especially critical for high energy efficiency requirements. Whether it is the best solution, however, always depends on the building, the desired energy standard and the overall window system. Not only is the glazing key, but also the combination of frame, gasket and professional installation. For energy-efficiency newbuilds and renovations, triple glazing is often an outstanding choice as it noticeably improves thermal insulation, brings down heating costs and simultaneously provides soundproofing. At the same time, the solution always needs to suit the house and planned use. Good thermal insulation is therefore not a result of a single feature, but a coordinated overall system.
