The roller blind box (1) has a thermal damping body (2) divided longitudinally into at least two parts (21, 22), linked together to swing in relation to each other round an axis (24) along the body. In one setting, they increase the dimensions of the heat damper body (2) and, in the other setting, their height is less than the height of the damper body (2). The body parts (21, 22) are of shaped foamed plastics, pref. of polystyrene or polyurethane.
