<p>The porch roof is made from prefabricated units, and comprises a closed roof frame, of light metal or other parts, enclosing membrane, bracket arms, fixing media and under-view screening, with a peripheral rainwater gutter formed by its shaped underparts. Frame membrane and screening combine to form a fully enclosed space containing forward tapering bracket arms and shared fixtures for these. At its top end the membrane is inserted by a retaining section into a top shaped section of the frame, the bottom end being locked by an elevated autment into a frame groove, and held there by a holder unit engaging on top of the membrane. The underview screening is locked in place by insertion into parts of the frame.</p> |
