We are offering a novel new sound deadening solution for the Triumph Herald and Vitesse. The Canley method of noise insulation was a glass-fibre wool encased in a polythene bag; roughly shaped to fit the required area, it was then simply stuffed behind the trim panel. It could be found in the doors, rear quarter area, under the gearbox cover and under the dash area (held in place by the fibreboard under-dash trim panel). It arguably did little to lessen the din inside the cars, however it provided an ideal soak-away for any water accumulating inside the door and rear quarter panels - acting as a sponge and contributing to the cars’ corrosion issues. Often the first thing people did when buying a second hand Herald or Vitesse was to remove it! We have therefore decided to use a modern specification foam for the under dash area, and developed this 6 piece insulation kit to reduce engine acoustics and drumming forward of the doors.
