摘要
A method of applying a transparent foil material on a gable roof of a greenhouse, wherein the gable roof comprises a roof frame including two gutter profiles, a ridge profile and two intermediate profiles extending parallel to each other, wherein the intermediate profiles are located between the ridge profile and the respective gutter profiles, wherein at either side of the ridge profile the gutter profile, the ridge profile and the intermediate profile are interconnected through lateral beams extending in transverse direction of said profiles, wherein the roof also comprises two window frames, located at either side of the ridge profile, each window frame having an upper window beam which is mounted to the ridge profile and rotatable with respect to the ridge profile about a pivot axis extending in longitudinal direction of the ridge profile and a lower window beam located at a distance from the upper window beam, wherein each window frame is rotatable between a closed position in which the lower window beam lies at the intermediate profile and an open position in which the lower window beam lies at a distance from the intermediate profile above the intermediate profile, comprises the steps of positioning the window frames in their open positions, laying a piece of the foil material onto both window frames and subsequently, fixing said piece to the lower window beams.
