The system is destined for building winter gardens and other space structures. The structure of system roof slope can be made with application of front sections, used in NT152 system or on the basis of system sections NT152WG of inverted rafters.
The whole can be based on front posts, posts from window and door systems as well as also on system reinforced posts NT152WG. The system of roof rafters enables to use standard window pane boards from window and door systems. Connection of rafters and beams is as identical as in the front system NT152. Elements of roof slope are fixed by means of hinge connection on a wall beam as well as system joints on an eaves beam with a system gutter of eaves. The roof system is completely compatible with available in Ponzio offer sliding and window-door systems.

Characteristics of system

• allows to combine profiles of NT 152WG system with other window and door systems: among other things PT52, NT 60, NT 68, PE 78, SLIDING 900, SLIDING 1200TT – it enables to build very complex and complicated structures (used in elements of eaves beam and wall beam, ”articulated joint” system allows to rotate a roof plate within 7 to 45 degrees of slope with respect to horizontal direction)
• used solutions make profile prefabrication easier
