Additional NotesHot uncomfortable journeys are a thing of the past!! This woven cloth with a silver foil on one side reflects the heat from the engine bay to vastly reduce heat in the cockpit and foot wells. Only 1.6mm thick and weighting only 1000grams per sq metre. This material is 1metre wide and is sold as required by the metre. To insulate a Healey 2 metre’s is usually sufficient.
