A method of manufacturing a lightweight thermal insulating cellular cement-based material and a lightweight thermal insulating cellular cement-based board made thereof are disclosed. A binder, an activator, and a blowing agent are mixed to obtain a mixture. The mixture is homogenized to form a cement slurry, which is poured into a mold afterwards. With the help of the activator and an increased temperature of the mold, the cement slurry in the mold will be activated and start foaming and curing to form a cellular cement-based material. The cellular structure is constructed by decomposition of the blowing agent to form a plurality of closed-cell bubbles, which are fixed in the cement slurry during the curing. After the formation, the mold is removed to obtain the cellular cement-based material. The material exhibits high integrity fire resistance and extraordinary insulation fire resistance.

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.
