Application types Description Ceiling, roof 1 The abbreviations used refer to areas of application for thermal insulation. Graphical symbols are given below this table. 2) I ncluding application from below, in contact with the outside air. 3) Area of application/abbreviation WAP does not apply to insulation boards in external thermal insulation composite systems (ETICS). ETICS are not a standardised application. 4) The specifications according to DIN 4108-2 are applicable.

1 When using sheet asphalt screeds, temperature-resistant insulation materials (ds or dx) are required for the insulation layer directly below the screed.
