Did Steve receive any guidance in reply to his question? I have a static caravan with yellow 'roof' type insulation underneath it, held in place by heavy duty polythene and I wonder whether this work was carried out by the previous owners or whether it was manufactured like this? However, wildlife has managed to tear the plastic and has been 'stealing' the insulation, so I am wondering whether to remove the whole lot, rather than trying to repair it.
