PHS TRS Expanding Foam Tape

PHS TRS Expanding Foam Tape
PHS TRS Expanding foam tape has a combination of resilient foam and water resistant binder.

This creates a slow expanding pre-compressed, expanding foam tape that is used to resist weather ingress in fenestration, roofing, and other construction applications. Its visco-elastic property offers noise/vibration damping while its impregnated foam structure provides an energy efficient thermal barrier. PHS TRS allows some movement of the structure whilst ensuring that the airtight seal remains constant.
