RENSON® offers with the Fixvent® and Fixscreen® Mono AKEVO an aesthetic and comfortable solution that is windproof sun protection, insect protection and - for the Fixvent® - also combines ventilation. Both products can be combined with each other within the same project as within the same space thanks to their same "look & feel". They can be placed easily and smoothly on all window depths of 50-215 mm, whereby an easy (dis) assembly of the fabric roller is guaranteed by the patented Connect & Go® s Click & Safe® technology. Both the cabinet and the cloth meet a high stability and strength. On the one hand, official tests (according to STS52.0 standard) with high wind load on the window, only minimal deformation of the cabinet. On the other hand, the Fixscreen® technology for a tight and windproof fabric up to 130 km / h. Thanks to the Smooth technology, which the zipper guides provided with a patented wear-resistant layer, the fabric moves up and down smoothly and silently.
