A construction element has the dimensions of formwork panel sheets of elemental concrete formwork and a thickness substantially less than at least one of its other dimensions. In terms of weight, the construction element is comprised of more than 50% plastic and less than 50% small, thin pieces of metal. The pieces of metal are distributed statistically evenly in the plastic, shorter than the construction element is thick, and preferably made of aluminum. The thermal transfer coefficient of the construction element is at least that of wood/plastic casting boards.

A building construction element of which the thickness dimension is substantially less than at least one of its length and width dimensions, having the following features: a) in terms of weight, the construction element comprises more than 50% by weight plastic and less than 50% small pieces of metal selected from the group consisting of aluminum foil and aluminum alloy, the construction element being comprised predominantly of the plastic and the pieces of metal; b) the pieces of metal are oriented irregularly and essentially evenly distributed in the plastic; c) the pieces of metal have a longest dimension that is less than the construction element is thick; d) the construction element has the dimensions of formwork panel sheets of elemental concrete formwork; and e) the thermal transfer coefficient of the construction element is at least that of multilayer casting boards made of a plurality of layers of wood bonded by intermediate layers of plastic.
