The wireless electric roller blind is a product that can be installed in any room. It will be perfect in the living room, bedroom as well as in a spacious office. It not only limits the penetration of sunlight into your interior, but also has a decorative function. High-quality fabrics effectively protect the room from the outdoor environment. If you want to control multiple blinds at the same time, you can buy our 15-channel remote control accessories in our store.
Klemmfix without drilling and with drilling: our electric blinds offer versatile installation options. Thanks to the Klemmfix system, they can be mounted without drilling. With the clamp mounting, you can avoid drill holes and possible damage to your windows and frames. (Clamp holder suitable for 15 - 25 mm window casement thickness) Fabric width 3 cm narrower than carrier outer dimensions.
In the production of our roller blinds, we first used a polyester fabric as the fabric material. The back has a light blocking coating and has a different colour than the front. This silver coating gives you additional benefits. In addition to blackout, it also gives our roller blind model insulating properties, as it repels heat in summer and keeps heat in the room in winter.
During our promotion we give free solar panel. The thermal blinds have built-in lithium batteries and can be easily used with our free solar panel for power supply. In addition, they can also be charged via a USB-C charger. We recommend mounting the solar panels in places where enough solar radiation offers.
