Induction welding for TPO and PVC roof systems
Electromagnetic induction welding is a relatively new attachment method for TPO and PVC single-ply roof systems. This attachment method is commonly referred to as Rhinobond or InvisiWeld. The process relies on special TPO or PVC plates that are found directly beneath the roof insulation. The plates serve two purposes. First, they are used to attach the roof insulation or cover board to the structural roof deck. Secondly, since they are coated with the same material as the roof membrane, they are welded to secure the membrane. It is important to note that the plates are roof system-specific. For example, TPO plates can only be used with a TPO membrane and PVC plates can only be used on a PVC roof system.
