(57) There is disclosed an insulated concrete panel with a reinforced 3, supporting back
wall 2, a thick layer of insulation 6, 7 and a relatively thin concreted front wall
11 without reinforcement. The concreted front wall 11 is divided into sections or
fields 12 which are divided by crack indicators 15. The crack indicators 15 are covered
by a slide film 17, 18. The front wall 11 is covered by a plaster layer 10 which is
reinforced by a glass fibre netting 9.
When the front wall 11 is subjected to actions of force, e.g. by the wind or push/pull
in the building parts or by thermal actions, the crack indicators 15 and the slide
film 17, 18 will provide for distribution of the stresses arising in the concrete
panel in each field 12 in the front wall 11. These stresses are distributed to the
glass fibre netting 9 in the plaster layer 10 over the crack indicators 15. The risk
of crack formation in the surface of the concrete panel is thereby reduced.
A method for making the insulated concrete element and its use are also disclosed.
