<p>The solar heating panel, has glass roof plates (4) each of which is flat or slightly rounded with its side edges bent up at an angle of about 40 degrees. The edges of each pair of adjacent roof plates (4) are embedded in mastic and covered by a line of ridge tiles. These are curved to fit over the bent edges of the roof plates (4) so that these are retained by their elasticity. A decorative timber plank can be used instead of the line of tiles.</p> |
