PIR-based heat-insulating material belongs to a special class of thermosetting polymers with a gas-filled closed cell structure containing a permanent inert gas responsible for reduced thermal conductivity. One of the features of PIR is its specific chemical structure, which is characterized by a combination of a rigid ring molecular structure and strong high-density chemical bonds. These features provide increased thermal resistance of the insulation, as well as resistance to fire. The carbonizing substance on the surface of the material when exposed to flame leads to the formation of a “porous” protective carbon matrix, which prevents further thermal decomposition of the inner layers of the polymer, contributing to the preservation of the integrity of the building structure with PIR. Thermal insulation boards PIR have a long service life, due to the fact that they have minimal water absorption, are not subject to the destructive effects of aggressive media, as well as decay, incl. in high humidity conditions. PIR boards have straight or molded ends in the form of an “L” -edge to improve the joining of the material to each other and create a continuous thermal insulation loop without cold bridges.
Advantage of PIR plates:
Application of PIR insulation on a metal basis. Interior finishing with drywall or directly on the metal
Application area: Heat-insulating PIRs are used in civil and industrial construction when installing flat roof systems on metal and concrete bases with adhesive or mechanical fastening. Also, PIR thermal insulation boards can be used to insulate floors (including loaded ones) and facades.
