The invention relates to a concertina-like collapsable screen, e.g. a screen for heat-insulation, said screen comprising deformable, separated cells, adhered to one another with side surfaces. The disadvantage of this known screen is that the folding edges at the outer walls of the screen are apt to shown readily small dents or impressions, e.g. by lightly pushing, causing the impossibility of bringing back the screen in its collapsed position. The invention proposed a collapsable screen of the type described in the preamble, characterized in that each of two adjacent walls of a cell extending at an outerurface of said screen is provided with an edge strip and in that said edge strips on said two walls are adhered to one another, e.g. the edge strips may be adhered to one another in such a way that one of said both edge strips is folded around the other one and the three-layered construction does made is integrated by pressure, if necessary while adding heat.
