Window-door aluminum system used for making thermal insulation of elements for indoor construction such as: partitions, windows, doors, vestibules, glass cases, ticket box offices, bent constructions, etc. Doors are mounted on clamp hinges which significantly shortens the installation time. Construction depth of sections is: 44,6 mm or 52,6 mm depending on the option. Profiles are adapted to installation on clamp hinges. Permissible filling in the scope 1- 28 mm. It can be single glazing, thermal glazing, as well as ‘sandwich' type plates, polycarbonate (multi-chamber or solid), furniture boards, steel sheets (in combination with polyurethane, styrofoam or mineral wool). The appropriate glazing strips and gaskets made of synthetic rubber EPDM are selected depending of the filling thickness.
Profiles are made of the EN AW-6060 alley according to PN-EN 573-3:2009. Size and shape tolerances are compliant with the PN-EN 12020-2:2001 standard. Perpendicular section connections are obtained by cutting profiles at 45˚ and putting corner's profiles into the chamber, which can be picketed, twisted or kneaded. Transversal connections are made with the use of aluminum connectors which can be picketed or twisted. What is characteristic for this system is its close relations to AC-62 insolated window-door system, as well as other Morad systems. Such construction assumption made it possible to obtain and apply many compatible elements, e.g.: common beadings, corners, gasket strips, and window seals, cover gaskets, hardware and accessories. One of the effects of the unification is almost identical appearance both from the outside and the inside of the made products.
