Abstract
A thermal insulation structure for windows including a plastic multi-cell layer, a flat transparent plastic sheet supporting the cell layer, ribbing support for each cell on the flat sheet and a transparent adhesive coated on the flat sheet. The insulation structure is transparent to outside light and provides a simple means for significantly reducing heat loss through the window.
Claims17
A flexible thermal insulation structure which comprises a flat plastic sheet, a layer of plastic cells attached to said flat sheet, ribbing support for each cell on said flat sheet and a transparent adhesive layer on a first surface of said cells opposite the surface of said cells attached to said flat sheet, each of said cells having a depth and a major diameter of between about 1/8 inch and 11/4 inch, said structure adapted to be adhered to window glass and having a sufficiently low mass as to impose substantially no mechanical stress on said window glass, said structure being sufficiently flexible as to impose substantially no mechanical stress on said window glass due to temperature changes at the interface between said adhesive and said window glass and said cells having walls positioned to provide a common support or ribbing for adjacent cells.
