Rings / Grommets
Newmat rings / grommets are necessary for all penetrations made through the membrane to allow for lighting fixtures, sprinkler heads, registers, smoke detectors, etc.
Rings are made of either Sintra® or Komatex® material, and they vary in size, shape, and thickness depending upon the penetration.
The installation / securing of the rings is performed on site and is not part of the custom fabrication of the membrane.
