Purever UK – Product overview

Purever UK panels are manufactured by their sister company in Spain, they can supply continuous sandwich-type panels with a polyisocyanurate (PIR) core injected between two steel plates.

The products can be used for climate-controlled premises or conditioned sites, both for positive or negative temperature. This kind of panel is available in smooth, striated or micro-striated finish.

PIR components present an excellent insulation performance, they are highly effective and lightweight. They offer an excellent thermal conductivity, high resistance to weight, combined with versatility of production.

They are closed-cell insulation, which are injected between metal plates sealed during the production process. The result is a self-supporting panel, which insulation capacity barely changes over time.

The conditions for use are in accordance with existing regulations, and in particular are ready for application of the EN 14509 standard, relating to technical and mechanical resistance. The normal temperature range varies from -40ºC to +40ºC.


Purever UK – Panel Performance

PIR (polyisocyanurate)

Products with PIR (polyisocyanurate) nomination correspond with a polyurethane family in which the structure of isocyanate 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.

  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.
