The system is designed for the construction of exterior building elements that require thermal insulation.
The three-chamber design improves the functioning of the system and encourages investors to use it. The additional chamber increases the rigidity, so the PT60 can be used to make large-size structures.
The system allows the manufacture of both window structures and single and double-leaf outward-opening doors with different threshold solutions. It is also possible to make doors with a central hardware groove (so-called rebated).
The system provides easy installation of accessories, which significantly speeds up the creation of constructions.
