How much do you know about PIR Panels?

PIR foam, also known as polyisocyanurate foam, is a type of rigid insulation material commonly used in construction and building applications.

In building applications polyurethane (PUR) and polyisocyanurate (PIR) sandwich panels are widely used. PUR foam is the result of the reaction of a “polyol” component with a “isocyanate” component. In PIR foams, more to polyurethane formation, the isocyanates components react with each other to form isocyanurates.

The formation of isocyanurates is giving PIR foams an advantage against PUR foams regarding resistance to fire. PIR foams are notable for their ability to slow flame spreading and smoke production when compared to PUR ones.

Of course PIR panels exhibit excellent insulation performance and durability and this is the reason why they widely used in both residential and commercial construction projects to enhance energy efficiency and provide thermal comfort.

VIOPOL’s Research and Development department alongside with its valuable partners, have developed the new PIR foam system: V-PIR C-35-009 for the production of PIR sandwich panels.

V-PIR C-35-009 achieved the highest class regarding fire performance since it is classified as B s1 d0 according to EN 13501-1

Moreover V-PIR C-35-009 panels can achieve lamda values as low as 0.020 W/m.K making them an excellent thermal resistant material.

All the above combined with very good mechanical properties make PIR panels produced with V-PIR C-35-009 an ideal choice for energy saving and safety.
