Abstract
A transparent sheet, which may particularly be used as a glazing has a radiation-reflective coating and at least one window permeable to high-frequency radiation. The window includes an area devoid of coating. The window is formed within a region of limited continuous area of the sheet, in which the ratio of the area devoid of coating to the total area of the transparent sheet is at least 25% in the case of the distribution, when flat, of the uncoated and coated areas.
