Technical field, solution. Multi-layer plastics films with sealed-in air cushions, air-cushion films for short, in a film thickness of at least 0.10 mm with medium-sized nubs of diameter 10 mm and a height of approximately 5 mm or greater with approximately 8,100 nubs per square metre, made of polyethylene or the like are cut to a suitable size and fixed over surfaces endangered by hail and are capable of considerably reducing the impact even of table tennis ball-sized hailstones so that the residual energy is no longer sufficient to deform, to destroy or to penetrate the protected surface. Principal possibility of use Protection of motor vehicles, boats, aircraft, glass surfaces, greenhouses, skylights, plastic surfaces made of brittle material. <IMAGE>
