Abstract
Construction parts are protected against lightening by a layer which releases a cloud of ionized and ionizable particles to spread the area affected by the lightening flash and to fan out the current path. The layer may include additives which swell when heated to increase the volume and density of the cloud. An electrically and thermal conductive layer or two such layers each having predominantly one of these properties is provided underneath the releasing layer.
