Fixing To... Insulated Plasterboard
So you want to hang something on the wall, and your wall happens to be made of insulated plasterboard! Basically what this means is plasterboard backed with a sheet of insulation attached to it – these come in different thicknesses from about 20mm to over 100mm, and help increase energy efficiency, lowering your bills and carbon footprint. Some also have a foil vapour barrier between the plasterboard and the insulation.
Insulated plasterboard is widely used in new builds, but also in older ones which have been retrofitted. It’s usually used to improve the insulation of external walls and can be added to e.g. brick walls without taking up a lot of extra space.
