Project report HAVERKAMP window tints Neu-Isenburg

The object

With 65,000 sqm, REWE Group's logistics center in Neu-Isenburg is one of the retail group's newest logistics warehouses. Using state-of-the-art technology, over 24,000 dry goods are transported, sorted and stored. From here, REWE Group supplies the approximately 220 stores in the region.

The large warehouse, named RED 63, was completed in 2014. Large windows let in as much daylight as possible, and a glass bridge over the access road connects the warehouse with the administration wing.

The requirement

Shortly after the logistics center went into operation and the administration wing was occupied, the disadvantages of the extensive glazing became apparent for the first time. Although the windows let in a lot of daylight and sunlight, which promotes employee motivation and saves electricity for artificial lighting - the continuous sunlight, however, repeatedly caused the interior of the glass bridge in particular to heat up extremely. The accumulated heat was released into the adjacent stairwells as time went on, and after a while parts of the logistics hall and other adjacent rooms also heated up.

Those responsible at REWE Group were looking for a solution that, on the one hand, would not reduce the incidence of daylight, but on the other hand would reduce the extreme heat load. In addition, the view to the outside, especially on the glass bridge, was to be maintained.

The solution

HAVERKAMP film experts advised the following solution during an on-site assessment: coating the panes with tints (silver 20R sr Primus), which provides very good heat and sun protection, but only slightly restricts the view to the outside. The indoor climate is positively influenced by the coating with such a film.

The surface of the film is scratch-insensitive, durable and maintenance-free - further advantages for large window fronts of a commercial object.

Concerns on the part of the company that installation would interfere with ongoing operations were dispelled. The installation was carried out on the outside of the windows with the help of a climbing device. Deliveries and departures of the large trucks were not impeded. The logistics center and also the administration were able to carry out tours, trips and work as usual. "The installation of the films was an additional investment that was definitely worthwhile," emphasize those responsible at REWE. "Since the installation, the indoor climate has improved significantly. The work itself was absolutely trouble-free."
