ABSTRACT:
A plastic covered gutter connected greenhouse structure comprised of metal framing covered by superimposed layers of plastic sheets having an inflated area between the sheets providing insulation to the interior of the structure. The superimposed plastic sheets of adjacent greenhouses are secured to the gutter which inter-connects the same. In this respect, the outer edges of the gutters provide male and female elements having mating V-shaped sections provided with inter-fitting splines on opposing surfaces thereof between which the plastic sheets are clamped. The male and female members are fitted so that screw members which maintain the parts in assembly are threaded through an outer flange of the female member and are perpendicular to the inter-fitting splines.
