Plasterboard with Improved Nail Pull Resistance
The present invention is concerned with plasterboards including at least two layers A and B of different composition, wherein layer A includes a calcium sulfate binder and a synthetic polymer foam and the layer B includes a calcium sulfate binder and a surfactant foam and wherein the at least one layer A is a surface layer. Improved nail pull resistance can be achieved in lightweight plasterboards, if foamed synthetic polymer is present in a surface layer. The present invention further concerns a method for the production of corresponding products, an apparatus for the production of such products as well as the use of synthetic polymer foam in a surface layer to produce plasterboards with high nail pull resistance at a minimal amount of synthetic polymer.
