The EASYFIX Thermo roller blind can be attached to the window frame without drilling or screws. The adjustable clamp brackets can be set to fit almost any window frame and mounted accordingly. Adhesive mounting is also possible. The fabric is light-blocking and, thanks to its aluminum-coated back, is energy-saving in cold months and heat-reflective in warm months. The EASYFIX Thermo roller blind is operated by a chain that can be mounted on the right or left. To measure correctly: Please use only rigid measuring tapes, such as a folding rule. To determine the order width, measure from the center of the window frame on the left to the center of the window frame on the right. Please note that the fabric can run past the window handle. The order width minus 3 cm corresponds to the fabric width. Manufacturer's note: The color reproduction of the image may differ from the original item of the manufacturer.
