Not only does the new silicone sash gasket provide improved, permanent impermeability thanks to its durable, temperature-resistant material, it also optimises operation by noticeably reducing the closing pressure and minimising any noise during opening and closing. Its shape, which is adapted to suit the corner, is unique on the market: for the first time in the window industry, a special process has made it possible to also connect silicone seals permanently in the corners. This means that MACO is the first company to supply silicone gaskets on lift&slide units.
