The focus today is less on heating a building and more on cooling it. Solar shading is an ideal solution to control heat and regulate daylight. Until recently, architects, contractors and building owners immediately thought of interior or exterior shading. Polysun® has, however, introduced a unique concept to the market, combining its knowledge of glass with know-how around shading and light control, and integrating a blind, plissé, plissé black out or roller blind into the insulating glass. Relatively unknown prior to the previous edition of Polyclose, the company has built a strong reputation in the market with its solutions. At this edition of trade fair, Polysun® out with a number of revolutionary innovations.
With Polysun's systems® people can play with natural light. By tilting the system, it either blocks out sun and heat as needed or lets in sun, heat and daylight. With a proper form of control, this creates a dynamic facade that fits perfectly within today's requirements.
"Until a few years ago, this form of sun protection was unknown, but in the meantime we can already present a broad portfolio of references. These range from homes with two units to offices, hospitals, hotels, restaurants and other buildings with sometimes dozens or hundreds of systems. Each project is unique and requires a customized solution," says Managing Director Albert Contant.
"Our systems regulate the amount of light, but are also able to admit and block heat. What we are currently seeing is a choice within the residential market to equip the entire home with our systems. The fact that these systems require no maintenance is decisive for many. The highly reflective slats used in projects let light into the building, while the coating on slats "pushes" the heat out so that it stays cool inside. Solar shading in insulating glass achieves values equal to exterior solar shading. By choosing the right combination, we can get down to G-values of five percent."
Polysun® is meanwhile investing heavily in expanding and optimizing its range. To meet the stringent thermal insulation requirements, the move to special triple glazing was made. In today's windows, the combination of triple glazing with integrated solar shading results in thicker and heavier units. Therefore, Polysun started® a collaboration with AGC Glass Europe, which today enables a highly thermally and acoustically insulating solution with excellent light transmission to be offered by combining solar shading with Fineo vacuum glass.
This allows systems from a thickness of only 28 mm to be made. This dynamic solution is being extensively tested, and has also already been used in several pilot projects.
"The integration of motorized slat systems in double or triple glazing is an excellent solution for veranda roofs and skylights. When you cover such light sources with a cloth or permanent coating, you keep the heat out, but you also keep much of the light out, which is a problem especially on colder, darker days. Whoever installs cloths must take into account frequent maintenance so they don't get dirty too quickly," Albert Contant continues.
"We also offer a solution where we integrate our systems into heatable glass in the facade or roof. This perfectly eliminates the thermal bridge that everyone is familiar with with glass in the facade and thus greatly increases comfort. The combination of heatable glass with an integrated shading system makes this solution even more effective. With this, windows are no longer an energy loss and offer comfort."
As fenestration continues to expand, Polysun must® can also produce Venetian blind, pleated, plissé black out or roller blind systems with larger dimensions. For several projects and houses, systems with two simultaneous slat systems in one cavity have already been realized, making surfaces up to 12 m² possible. From the market, however, there was repeated demand for one-piece solutions. This is where Polysun® now in with a one-piece system for heights up to 4 m and areas up to 10 m².
The manufacturer is also in the process of expanding its options with plissé black out. Until today, this version was only available in white and cream, but as of Polyclose, eight different shades will be available, making it easier to match the system to bedroom interiors, for example. At Polysun® at least they are not sitting still, and the results can be seen at Polyclose.
