ABSTRACT:
A thermal insulation arrangement for a door or a window comprises a transparent sheet drawn down from a spring-loaded roller at the top of the frame. The sides and preferably the base of the sheet are sealed by brush seals in channel-sectioned members. The sheet may be creased in a pattern to reduce rippling and billowing.
