I am in the process of removing a partition wall which after some research appears to be a paramount partition. It has a cardboard egg box like structure between 2 sheets of plasterboard inside. On inspection, there seems to be a textured coating on the inside on the plasterboard sheets (see attached photo). The walls are branded Gyproc. Can anyone identify what this is? To me it looks similar to artex and I just want to take the right precautions if it is likely to contain asbestos. Our house was built in 1978 and the rest of the artex on ceilings and walls has been tested and came back positive for asbestos. Any help is much appreciated.
