Ease of use
The system is characterised by extreme user-friendliness: the flush threshold, for example, allows barrier-free access to any user (elderly, children, disabled persons) while the surface water drainage integrated in the system preserves its sealing performance. The new central gasket system meets the requirements in terms of weather resistance: in combination with the end stop integrated in the insulation batten, it can achieve a water permeability value of up to 300 Pa pressure (class 7A), class 3 air permeability and class C2 wind load resistance. The energy balance of the central seal system is also remarkable, thanks to insulation chambers with U(d) values below 1.4 W/(m2K).
