Abstract
An insulating plate element includes a heat insulating core layer (1) open to diffusion and which is coated on both sides with a diffusion-proof outer layer (4,5), the core layer (1) being divided into cells by means of diffusion-proof separating layers (3) that extend perpendicular to the diffusion-proof outer layers (4,5) and are connected thereto in a diffusion-proof manner.
Claims13
Insulating plate element comprising a heat-insulating core layer (1,10) open to diffusion, with a vapor-proof outer layer (4,5;
- 19,20) coated on opposite sides of said core layer, and a plurality of vapor-proof separating layers (3,15) which extend through said core layer perpendicularly to the vapor-proof outer layers (4,5;19,20) and which are connected to said outer layers in a vapor-proof manner.
Method of producing an insulating plate element comprising the steps of applying a vapor-proof layer (11) onto at least one side of a plate or a web (10) of an insulating core material which is open to diffusion, cutting the plate or web thus produced into lamellae (12), turning the lamellae (12) 90.degree. about longitudinal axes thereof and adhering said lamellae to each other to form a plate, strips (15) of the vapor-proof layer forming a separating layer between adjacent lamellae (12), coating both sides of the plate or web thus produced with a vapor-proof outer layer in such a manner that vapor-proof connections are obtained between the edges of the separating layers and the outer layers (19,20), and cutting the web into desired lengths.
