Window thermal insulation device

摘要

Window thermal insulation device for thermal insulation of a window opening area, including a plurality of linear members arranged in successive end to end relation for forming a perimetric selectively sized and shaped enclosure frame defining a window space therewithin, a like plurality of interconnectors for interconnecting the adjacent ends of the linear members, linear locking grooves in the linear members and extending therealong peripherally outwardly of the window space, a pliable plastic thermal insulation sheet extending across the window space of the frame and having its peripheral margins disposed correspondingly in the locking grooves of the linear members, a like plurality of linear cover strips having linear locking tongues projecting therefrom and disposed correspondingly in gripping contact with the adjacent portions of the peripheral margins of the plastic sheet and in releasable locking engagement with the adjacent locking grooves and arranged for maintaining the plastic sheet in substantially taut condition across the window space, and perimetric compression thermal insulation sealing means, e.g. of resilient compressible sponge material, extending along the linear members peripherally outwardly of the enclosure frame for compression sealing contact peripherally outwardly against a counterpart receiving frame portion of an existing correspondingly sized and shaped window opening structure to be thermally insulated thereby, preferably with retaining insert means being provided in the ends of the linear members for correspondingly receiving the interconnectors thereat.
