This system enhances the energy efficiency of the middle chamber of the profiles by up to 38%, ensuring thermal insulation. At the same time, the glass-reinforced insulating bars provide high static resistance. Using the Total Sealing System, the waterproofing issue has been addressed holistically. The design perfection of the components combined with the selection of suitable materials make the W59 SI2.ML series impenetrable.
It is available in three levels of energy efficiency.
