Penetration Seals

Greyton can provide solutions for all services penetrations and Fire sealing penetrations in walls, ceilings and slabs. We use a wide range of products to achieve the required rating whatever the parameters are. Some of the systems include:

  • Non-shrink fire rated mortar to pipes and cable penetrations
  • Fire rated ‘pillows’ both intumescent and mineral wool installed around pipes and cables.
  • Intumescent collars, wraps and pastes for all plastic pipes or conduits passing through large slab or from fire sealing penetrations proof wall or ceilings. This may involve constructing fire rated bulkheads to accommodate collars where it is not possible to retrofit them.
  • Fire rated calcium silicate, Fire sealing penetrations, vermiculite and Rockwool boards to both wall and floor penetrations.
  • Flexible fire rated foams around pipes where expansion and contraction is important. This is usually part of a fire mortar system.
  • Mastic seals, acrylic or polyurethane, around cables and pipes where core holes or small penetrations are required. Fire rated and non-fire rated backing rods are used to compliment the performance of the system.
