The A59S system is intended for production of both tilt windows and outswing windows. Almost all window and door sections have a three-chamber structure, where the central chamber is the insulation chamber between thermal breaks. 

Thanks to such a solution it was possible to obtain slender, economical and rigid profiles. The system of connections with thermal break allows application of double-colour profiles – different on the internal and the external side of the façade. In A59S system, there are profiled “omega”-shaped thermal breaks, made from polyamide reinforced with fibreglass. Such a shape of thermal breaks ensures very good thermal insulation and the proper drainage from internal chambers of the profile.
