Abstract
An edge seal for a solar collector type flexible film material is provided for forming a generally air-tight heat insulating reusable seal around the edge of an opening in the surface of a building structure. The edge seal is formed around the film material which is sized to cover the window opening and overlap the edges of the opening. A band of magnetically permeable particles is adhered along the edge of the substrate forming the film material by a suitable adhesive. A strip of magnetic material is adhered around the edge of the opening. The permeable particles are attracted to the magnetic strip to form an effective air-tight seal between the flexible film material and the opening to essentially form a dead air space between the flexible material and the window opening. The flexible film material can be mounted similar to a window shade adjacent to the upper edge of the opening. The film material can also have a monolayer of transparent spheres adhered to one side which provide a means for concentrating solar energy striking the outer surface of the sheet material. The solar energy will be converted to heat energy and conducted through the sheet material to the interior surface so that the heat will be transferred to the interior of the building.
