From the evolution of Key Design technology comes FanGlass® Thermic, an exclusive foldable system, which guarantees all the comfort of double glazing for better insulation of the environments. The Thermic system, made with a 25 mm glass, is suitable for installation in particularly rigid areas or at particularly high temperatures, allowing a heat reduction (or dispersion) of approximately 50% compared to the Standard solution. The system, like the FanGlass® Standard, unloads its weight to the floor and can therefore be installed on any type of structure without the need for structural reinforcements. The Thermic system, unlike the Standard one, has small vertical profiles between panels, which are inevitable in double glazing to cover the seal between the coupled glass. However, they have been designed to be minimal in order not to compromise the aesthetic impact of the glazing. The same guide profiles are used in the two systems (FanGlass® Standard and FanGlass® Thermic); this makes them interchangeable  without the need to make any type of modification to the tracks.
