Do I need to insulate the room


Although not essential, we strongly recommend the use of an insulated tile backer board (20mm) as this will help produce an efficient room which will heat quickly and provide confidence in a steam tight structure. If it is not possible to include insulation or the chosen wall material is particularly cold (marble, granite etc.) an up rated generator would be wise to ensure efficiency.

The Helo team will be happy to advise on this.
