Applying Wallrock Thermal Liner, do we need to take off the existing wallpaper?

No, if the existing wallpaper is firmly stuck to the wall then Wallrock Thermal Liner should cover it, however if it has a deep pattern (more than 2.5mm) or is a Vinyl based paper we would recommend that it is taken off before applying the Thermal Liner.
