Abstract: A greenhouse construction is provided for support against a supporting structure such as a house. The greenhouse construction comprises a glazing structure consisting of glazing and glazing bars. There is also provided a ridge which supports the glazing structure against, but spaces the same from the supporting structure. The ridge includes openings respectively opening into an enclosure defined by the glazing structure and into ambient atmosphere and there is also provided a blower which exhausts air from the enclosure and expels it into ambient atmosphere via one of the aforesaid openings. The ridge is provided in the form of a plurality of channels, one of which has a face adapted for abutting against the supporting structure and defining a pocket for receiving the glazing bars. Another of the channels is supported on the channel with the aforesaid pocket and this additional channel is provided with its own pocket for supporting a flashing structure.

Abstract: A method is provided for constructing a greenhouse or solarium structure with glazing and with provision for ventilation. This method includes supporting a blower in an enclosure having an opening for the venting of the greenhouse or solarium structure and supporting a channel on the enclosure. Inter-engaged with the channel is at least a portion of the glazing of the greenhouse or solarium structure and this is done such that the glazing and enclosure form a part of the structure such that air within the structure can be evacuated by the blower through the opening.

Abstract: A solar greenhouse construction is provided in which a glazing is supported by a supporting frame to define an enclosed space. The glazing is permeable to solar radiation. A shade is provided for being drawn across the glazing to intercept the solar radiation. A motor driven roller is connected to one end of the shade to play out the shade or wind the same up. To the other end of the shade is connected a constant force or constant torque device which overcomes friction and keeps the shade stretched out. This device consists of a coiled up spring which is reverse wound onto a roller to which is connected a cable connected to the shade.

Abstract: A structural arrangement is provided which is particularly useful in connection with solar greenhouses. The structural member is suitable for use in a parallel arrangement of the same particularly for the purpose of providing controlled shading. The structural member is provided as a hollow bar of elongated form provided with at least one longitudinally extending track channel having a relatively narrow longitudinally extended slot-mouth. The bar may be provided with two such channels and these channels are substantially circular in cross-section with the mouths defining reentrant angles therewith. In a solar greenhouse, members of the above type support a glazing with a curved-eave section, the bars being curved to shape and the channels therein accommodating the bulbous lateral edges of shades which are retained therein. The shades are transferred from one roller in the direction of a second roller.

Abstract: In one form a greenhouse or solarium is provided in which the glazing is spaced from its supporting structure by channels employed along the end edges and top edge of the greenhouse or solarium structure. The spacing is effected by the use of channels which extend entirely along the end edges to obturate the space between the end edges and the supporting structure. Additional channels are provided in parallel with each other at spaced positions along the top edge of the glazing in order to connect the same to the supporting structure and space the top edge from the supporting structure. This develops an opening adjacent the top edge of the glazing which is covered by a shed mounted on the supporting structure. Suitably positioned fans are used to exhaust air from the enclosure formed by the glazing and a flap closing is provided for the opening adjacent the top edge in order to selectively obturate the same. A roll down cover is provided whereby selective covering of the glazing is enabled.
