PIR

PIR (polyisocyanurate)

Products with PIR (polyisocyanurate) nomination correspond with a polyurethane family in which the structure of isocyanurate polymer is modified. These structures are consequence of the reaction of molecules of isocyanate with an excess of themselves, giving the final structure a remarkable stability in case of thermal aggression like for example a fire.

 

The latest technology with regards to components and production processes established in PAP, along with the innovative design of the panels has allowed obtaining the B-s1, d0 classification for the range of PIR panels according to the European norm 13501-1.

 

This makes PAP´s PIR range of products the optimal election for the vast majority of the applications of construction and isolation, fulfilling as well a wide range of requirements of performance against fire as well, according to what is stipulated by the current European norms. This turns PAP´s PIR range of panels into the best option to give answer to the needs of an increasingly demanding market when it comes to quality, security, hygiene and isolation.

 

Key features:

  • PIR heat resistance reaches 163 º C
  • Bs1d0 according to standard UNE-EN 13501-1:2007 + A1: 2009, without special mounts, meeting the requirements of the CTE (DB-SI) and R.S.C.E.I.
  • Favorable assessment by insurance companies due of the presence of PIR in panel composition.
  • Lightweight and easy to handle, allowing to save assembly costs.
  • Mechanical strength avoids the risk of insulating foam lamination.
  • PIR foam does not absorb water, preventing the deterioration of the insulation.
  • Closed cell structure that allows the conservation of the enclosure in good condition.
  • Fire behavior much higher than conventional foams.
  • No flame spread
  • Smoke levels: zero or low level.
