<p>The present invention relates to a device (1) for reflecting electromagnetic waves, particularly light and heat radiation to a regulable extent, wherein between two protective plates (3) substantially transparent for electromagnetic waves the device (1) comprises a sheet-like, flexible reflecting element (2) of similar width and of larger length as compared to the protective plates (3) for transmitting the electromagnetic waves to different extents and/or in different ways, the device (1) further comprises a driving means (4) for spanning the reflecting element (2) along the longitudinal directions of the protective plates (3) and moving it in the same direction. The protective plates (3) are connected to each other so as to enclose an airtight space and the reflecting element (2) is arranged between the protective plates (3) in the airtight space. The invention also relates to a method for the metallization of a film with a density varying with the longitudinal position on the film according to a given function.</p> |
