Thermal wallpaper: Wallrock KV600 (Hollingbury BN1)

This is thick wallpaper that can help to reduce heat loss through a wall. We had this bit left after doing a small room. Also, there is some fire retardant paper that needs to be used with it. There's not enough here for a whole wall, but it could save you some money if you were going to buy some of this stuff (it's expensive). We may also have some of the special wallpaper adhesive you need to use with it.
