Heat insulating layer for domestic oven - is foam mixture embedding insulating material applied on outside surface

摘要

The heat insulating layer is used in an electric domestic oven, the oven compartment being pref. enclosed by insulating foam material. The foam mixture consists of distributed insulating material and liquid. This mixture is applied to the oven housing outside surface by brushing, spraying or by immersion. The coated housing is subsequently dried. The housing can be coated at first with an intermediate layer with insulating material with high insulating properties. Subsequently, a layer with insulating material with lower insulating properties is applied to the intermediate layer.
