Geotec 220Py Lead Underlay 25m Roll

  • Geotec 220PY underlay is particularly suited to use on existing traditional timber board substrates. 
  • Non-woven, needle punched polyester textile underlay, conforms to the Lead Sheet Associations requirements.

Its special composition prevents ridges and fractures forming in the lead sheet where thermal movement causes it to pass over the edges of individual boards.

Weighing only 220g/m2 this non-woven, needle punched, polyester textile underlay conforms to the requirements of the Lead Sheet Association.
