ABSTRACT:
A G.R.P. roofing panel is stiffened by longitudinal beams on its underside and is designed to span one pitch of a pitched roof from eaves to ridge. It has an outer skin and an inner impervious liner spaced therefrom and supported on the stiffening beams so as to form a tunnel open at both ends and extending from the vicinity of the eaves to the line of the roof ridge, where vents to atmosphere are provided in the outer skin. Air is convected upwards through the tunnel due to the heating of the outer skin by radiation from the sun, and a damper controls this flow of air. It can be arranged to operate differentially on air flowing in from outside the building and air flowing in from the roof space through a port in the liner. At the line of the ridge the liner meets and is sealed to the corresponding liner of a counterpart panel on the opposite pitch of the roof so as to maintain the integrity of the convection air circuit in each section of the roof. A heat exchanger suitably located in the tunnel transfers heat from the convected air to a hot water system in the building. A hollow box girder spans the width of the panel across the beams so as to rest on the top of a flank wall of the building and can be filled with concrete to anchor the panel in position.
