I was putting laminate down at the weekend (one single piece throught the entire ground floor!!) and I wanted to insulate it. I couldnt stretch to the expensive foil backed stuff so I laid the cheap B&Q white foam underlay and went to the pound shop and bought some rolls of 40 foot tin foil and laid that on top and then laid the laminate. Worked a treat. Anyone think this was a good/bad idea? Commence the pee taking.
