Abstract
The invention relates to a dark, flat element, preferably a plastic, lacquer coating or fiber material, having reduced density, low heat conductivity and low solar absorption. The flat element has a relatively high reflection infrared range of the electromagnetic spectrum reduce heating by sunlight in the near infrared dark tinting in the visible range. Low density conductivity are obtained inter alia by inserting in the near in order to area despite and low heat light filling materials into the flat element. Said flat element can be used in places where surfaces are dark tinted for aesthetic or technical reasons but should not heat up in sunlight and should give off little heat when touched by hand or by other parts of the body. Other areas of application include surfaces which should have a heat insulating effect in addition to the above-mentioned characteristics.
