sandwich Panels
Polyurethane (PUR) and polyisocyanurate (PIR/PIR+) foams are expanded plastics produced as a result of a polyaddition
reaction with isocyanates in the presence of activating and stabilizing agents. As the blowing agent we use a traditional
hydrocarbon - pentane, which is perfectly safe for the ozone layer. By using special polyester-derived polyols in
polyisocyanurate (PIR/PIR+) foams, we obtain more aromatic bonds. Additionally, by means of increasing the so-called index
in appropriate conditions, polyisocyanurate rings of high chemical resistance are produced. As a result, in comparison to
flat rings in the PUR foam, in the PIR/PIR+ foam three-dimensional structures are obtained.
The effect is that the PIR/PIR+ foam behaves much better in fire than the PUR foam. It also exhibits better mechanical and insulating properties. PUR/PIR/PIR+ foams are characterised by very good physical and chemical parameters, high resistance to moisture, high chemical resistance and resistance to fungi and mildew. Compression strength with 10% deformation is 150 kPa, with density of 40 kg/m3± 3.
We offer a range of Headstream PIR-cored fire resistant insulated panels for all types of temperature controlled applications & controlled environment projects.
The high thermal performance of the PIR (PolyIsoCyanurate) core offers higher energy savings and/or reduced thicknesses of construction when compared to other insulated panel systems. They are fire resistant, hygienic and fibre free.
Applications
PUR/PIR/PIR+ sandwich panels are manufactured in a process of continuous foam pouring between the steel sheet lining. They are designed for use as wall and roof components of industrial, storage and public utility buildings. They are also used as insulation in the food and refrigeration industries as components for cold rooms and freezers. They may also be used in agriculture as components of farm facilities. Another example of application is thermal insulation in building engineering. Thanks to the variety of profile types of panel plates lining and a wide selection of paint coats in various colours, our products can give a unique character to any building. Additionally, panels with the PIR/PIR+ foam core may be successfully used in buildings with higher requirements for fire resistance.
