Facade construction

A pretty shell with a good core.

Technically perfect and visually stunning shells made of metal and glass make every building prettier. Together with the specialist ALU-SOMMER (German website), PORR offers all clients the best possible solution.

For 50 years, ALU-SOMMER has been implementing aluminium-glass construction projects in the field of building envelopes all over Europe. Their product portfolio ranges from simple windows to ready-to-install element façades. Thereby, no façade, no construction scheme is like any other which is why they require individual solutions. Thanks to in-house development, tailored design, high levels of depth of production as well as internally processed installation, ALU-SOMMER produces demanding turnkey-ready façades, simply “pretty shells with a good core”.
