EN 15318:2007 – Design and application of gypsum blocks

1 Scope
This European Standard defines the rules for the design of gypsum blocks as specified in EN 12859, assembled with adhesives as specified in EN 12860. Accessory products are also defined in this document. It is applicable to non-loadbearing partition walls and internal insulation of walls in rooms of residential buildings, offices, hospitals, schools etc. and to linings of posts, beams, ducts, shafts etc, that are suitable to receivefinishes such as paint and wallpaper without any prior traditional plastering, but having had normal preparation prior to painting.
Certain components requiring special provisions are not covered by this standard and require special consideration.
