PIB Rubber Sheeting

  • Will not harden
  • Will not crack or Peel
  • Virtually non-ageing
  • Ozone resistant
  • UV Resistant

 PIB is a weatherproofing material for insulated ductwork and pipework. It is produced from high molecular weight polyisobutylene, modified to achieve optimum properties.

Tests carried out after 20 years have shown no significant alteration to the properties of the material, consequently no maintenance is required. We do recommend periodic inspection of large ductwork installations to repair damage if necessary.
