The translucent heat-insulating plate is formed by a stack of sheets (2), each with embossed portions (9) forming a profiled surface. Those in each sheet are of the same )shape, with their axes at right angles or inclined to the plane of the sheet, and form supporting distance-pieces for the next sheet in the stack. Where their surfaces are flat, each includes with the axis an angle of less than 40 deg. Where they are curved, half the internal angle at the apex is likewise less than 40 deg. ADVANTAGE - Minimum reflection and absorption losses from sunrays passing through.
