Transparent heat protective foil consists of a plastic foil and a selectively reflecting alternating layer system on an abrasion protective layer. The novelty is that the layer system consists of corrosion-resistant metal, oxide, nitride and/or oxynitride layers and the abrasion protective layer consists of at least 1 (pref. 2-5) mu m thick, highly transparent and homogeneous amorphous oxide layer having a high packing density on a microhardness of at least 4 (pref. 5-10) GPa. Production of a transparent heat protective foil is also claimed. USE - The foil can be applied to outside surfaces of car and building windows. ADVANTAGE - The foil has high service life.
