A bright white wave
A certain amount of skill and a high level of sensitivity in design and planning are required when attempting to integrate a new building into a historical ensemble. On the one hand, there is a risk that the building with its modern dimensions could seem out of sync with its surroundings; on the other hand, its features could be too antiquated, making it look pretentious. A problem the Hamburg-based Architects Köhler Architekten solved skilfully when designing the so-called "Ice loft" in the district of Ottensen: The classical façade structures of workmen's and bourgeois houses in the district were reinterpreted and their surface was covered with the modern HI-MACS® material, designed to give it a contemporary look.
The amazing design possibilities and functional advantages of HI-MACS®, as a façade material, are particularly evident in non-weight-bearing ventilated façades such as the one here in Hamburg-Ottensen. Heat insulation and weather proofing are functionally separate areas in this very common construction variant. This is where the unique combination of relevant properties make HI-MACS® stand out, making it ideal for outdoor use. Links on the roof, floors and window sills can also be designed inconspicuously using a special subframe structure. It connects the panels in a professional manner, leaving sufficient air space for wall insulation. The insulation material can be fitted optimally between the aluminium profiles and the back wall. Depending on the type of building, the subframe structure is implemented individually according to the architect's instructions. The links between the HI-MACS® panels and the aluminium frame remain invisible from the outside. The incredible moisture resistance of the solid surface material also protects the façade insulation layer behind it. The space between the façade panel and the insulation material perfectly diverts moisture to the outside and allows for perfect ventilation in the summer and the winter. In regard to fire resistance, HI-MACS®-S728 in Alpine White received a fire rating of B-s1-d0 (as per EN-13501-1) in the SBI test (Single-Burning-Item), beating all other mineral-based materials.
