Perimate provides high performance insulation for below-ground structures, such as exterior walls.

  • Protects tanking material from damage and helps to drain water away from the structure
  • Can be applied externally to insulate the structure in construction
  • Large quantities in stock in our Sheffield warehouse

Perimate can be applied externally to:

  • Insulate the structure in construction
  • Protect the tanking material from damage by the backfill material
  • Drain water away from the structure reducing hydrostatic pressure on the tanking membrane

Perimate combines unique features

  • Vertical channels to help drain water away
  • A thin fabric layer to prevent soil particles blocking the channels
  • Shiplapped edges to ensure continuity of insulation

Uniquely designed and distributed by Panel Systems, Perimate can prevent ground water reaching the interior of a building by insulating below ground structures. A common solution is to use a tanking membrane of mastic asphalt or bituminous sheet applied to the external wall.

We pride ourselves on our high level of quality & service and all our products are manufactured to British Standard BS EN ISO 9001:2015. We keep extensive stocks at our Sheffield warehouse close to Junction 31 off the M1, ready for collection or distribution across the UK.
