The system is dedicated for making elements of outdoor development, requiring thermal insulation. The structures made in the NT 52 system are classified as the RMG 2.1 material group.
The system offers the possibility of applying a number of solutions in completing various types of windows, doors and spatial structures. The thermal spacers applied, with width 16 mm (straight and omega-shaped) ensure the proper dewatering of the structure.
The depths of the sections for the door frames and leafs is equal to 52-60 mm.

• windows and doors capable of being inserted into façade systems
• capable of facing the plane of windows (one plane on the exterior side) and door (both planes both on exterior and interior side)
• application of transparent or non-transparent fills with thickness 1-40 mm
• bending profiles
• capability of applying modern double-component EPDM gaskets with perfect thermal performance, aesthetic appearance and simple in assembly
• several variants of door leafs completion
• several methods of completing corner joints through screwing, bolting or crimping
