SK, SKE and SKP system-based roller shutters are intended for use in existing buildings. The advantage of these products is that they do not require any special pre-installation preparation nor works to the existing structure as they are not integrated with the window. Buyers can thus decide to install the front-mounted roller shutters at any time. These solutions can be mounted to the window joinery (in the recess) or directly on the wall. In the first case, Aluprof recommends to choose half-oval SKP boxes systems, as they perfectly match the external wall, or SK and SKE systems (version with extruded box) with its box cut at an angle of 45°.
The roller’s curtain is usually made of high quality aluminium sheet filled with polyurethane foam that have special two-layer paint coatings (system PU/PA). This makes the product more resistant to abrasion and weathering. Aluprof also offers profiles of greater rigidity and stability, made of extruded aluminium and plastic profiles. Front-mounted roller shutters can also be integrated with insect screens. This comprehensive solution provides effective protection against insects in summer, while protecting the interior spaces against heat loss in winter.
