In a plate-shaped insulation member consisting of parallel mineral wool strips positioned side by side with the fiber planes normal to the main surfaces of said members the strips are joined together by connecting means laid down in parallel tracks extending transverse to said strips and having a small depth relative to the thickness of the strips. The connecting means may consist of strings laid down in tracks either in one main surface only for production of flexible insulation mats or in both main surfaces for production of rigid formstable insulation plates. The latter may also be produced by connecting means in the form of relatively thin strips of corrugated wall board, for example, laid down in said tracks in an upstanding position. |
