Abstract
Abstract A method of controlling the solar heat effect in glass and plastic covered greenhouses, and other windowed structures, consists of coating the greenhouses with an adhesive film consisting essentially of synthetic silicon dioxide having an average particle size of less than 10 microns and a film forming plastic resin. The film is translucent when dry but becomes transparent when wet. The film also extends the useful life of plastic coverings by reducing ultraviolet radiation.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
133 words
A METHOD OF CONTROLLING THE AMOUNT OF SOLAR HEAT AND LIGHT WHICH ENTERS A GLASS OR PLASTIC COVERED GREENHOUSE OR SIMILAR ENCLOSURE COMPRISING THE STEPS OF COATING A LIQUID ON THE GLASS OR PLASTIC FILM OF THE GREENHOUSE, THE LIQUID INCLUDING A CARRIER, A FINELY DIVIDED SYNTHETIC WHOSE AVERAGE PARTICLE SIZE IS IN THE MICRON RANGE AND IS LESS THAN 10 MICRONS, AND A TRANSPARENT FILM FORMING PLASTIC RESIN, PERMITTING THE LIQUID TO DRY THEREBY FORMING AN ADHERENT DRY NON-TRANSPARENT COATING ON THE GLASS OR PLASTIC FILM, AND INCLUDING THE FURTHER SUBSEQUENT STEP OF REPEATEDLY PERMITTING THE WETTING OF THE SAID DRY NON-TRANSPARENT COATING ON THE GLASS OR PLASTIC SURFACE OF SAID GREENHOUSE WITH WATER TO MAKE THE COATING TRANSPARENT AD PERMITTING IT TO DRY BETWEEN EACH WETTING TO MAKE THE COATING NON-TRANSPARENT.
