Architect | Workshop | Jansteel


In a manner unlike almost any other product, Janisol 2 EI30 combines the legal requirements for structural safety with design freedom. The material properties of steel allow extremely slimline steel profiles to be assembled into strong and safe constructions. The result here is multifunctional doors that satisfy the requirements of both the architect and the client. The performance of the system has been internationally confirmed in numerous fire tests. Janisol 2 has been tested in combination with products from many different glass suppliers.
