The optimal construction of surface absorbing with the selective coating and the prismatic safety glass of 4 mm guarantee an extremely fast reaction of the sensor, even in the event of weak sunning. Its dark anodic aluminum framework makes it possible the sensor to adapt to the appearance of any surface. Thanks to its weak weight and with its system of astute assembly, it can easily be gone up on roof, integrated into the roof, on the frontage or support terrace. In combination with the systems of heating of Roth surface, collected solar energy can also be used in an ideal way to supplement the heating. During manufacture, Roth stresses the use of materials of great quality and on a perfect completion.
