ABSTRACT:
An existing glazing system using small rectangular plastic or glass glazing panels or using thin films, plastic glazing panels may be converted in an inexpensive manner to an elongated rigid, plastic glazing panel system having a condensate removal system. Very long glazing panels of plastic, preferably corrugated, are laid across several purlins in the vertical direction. The glass glazing panels or the thin film glazing panels are removed to expose the roof members. Purlins are laid across the roof members with ends of the purlins positioned intermediately adjacent roof rafters. Condensate collector channels on the purlins convey moisture to the ends of the purlins and discharge collected moisture to an underlying drain, which is fastened to and carried by the purlins. The drain is spaced from the rafter roof members. Very long glazing panels of plastic, preferably corrugated, are laid across several purlins in the vertical direction. Because the rigid, plastic glazing panels have edges that are located intermediate the roof rafters, the width of the rigid, plastic glazing panels need not be sized to match the width of the spacing between adjacent roof rafters. The drains are located in a plane beneath the plane defined by upper surfaces of the roof rafters. In another embodiment, the purlins are attached to and spaced above roof purlins by spacers to locate the drains above the roof purlins.
