What is PIR?

  • PDF

Polyisocyanurate insulation is a closed-cell rigid foam board manufactured with isocyanate and ployether mixed together in the presence of a catalyst that allows the molecules to rearrange, forming closed cells. Polisocyanurate (PIR) foam is similar in physical form to polyurethane but has improved insulating qualities. It has a wider operating temperature range that surpasses standard Polystyrene, and is fire and smoke resistant.

Rigid polyurethane foam(PIR) is one of the most efficient, high performance insulation material, enabling very effective energy savings with minimal occupation of space.

Better insulation in buildings is a significant contributor towards the implementation of the Kyoto protocol and will also bring additional benefits:

  • Energy savings, resulting in lower energy bills both for individuals and for countries. this will help to improve competitiveness of New Zealand and Australia as a whole.
  • Protection of the environment: more stringent insulation regulations can cut New Zealand & Australia CO2 emissions by 5%.

When it comes to insulating buildings, rigid polyurethane foam(PUR/PIR) is the cost effective insulant for new construction because it has low thermal conductivity, unmatched by any other conventional product. further, rigid polyurethane foam(PUR/PIR) is deal for renovation when the emphasis is on energy efficiency. Retrofitting insulation in the shells of existin buildings can cut average energy consumption by more than 50% and rigid polyurethane foam(PUR/PIR) simplifies the installation. Low thermal conductivity means thinner insulation for any specified insulation level and thinner insulation means it is easier to fit into the building cavity. The insulation performance is exceedingly high even with modest material thicknesses. Finally, good mechanical properties and excellent adhesion to other materials opens up a broad field of applications.

With their optimal insulating performance, insulation materials made of rigid polyurethane(PUR/PIR) are very versatile. The products range from insulation boards for roofing, walls, floors and ceilings, to window frame insulation and foam sealants, through to metal-faced sandwich panels for industrial buildings.

Efficient thermal insulation to last a lifetime

The term rigid polyurethane foram(PUR/PIR) stands for a family of insulation materials that, in addition to polyurethane(PUR) also includes polyisocyanurate(PIR) rigid foam.

The excellent thermal insulation properties of closed-cell rigid polyrethane foam(PUR/PIR) are achieved today mainly with blowing agents such as pentane(hydrocarbon) or CO2.

In addition to the low thermal conductivity, rigid polyurethane foam(PUR/PIR) is stable and durable. It will function for as long as the building stands and has a useful life beyond 50 years.

Thermal insulation with rigid polyurethane foam (PUR/PIR) conserves resources, saves energy and has no significant emission to the environment.

Rigid polyurethane foam (PUR/PIR) is the right investment for the future as it;

  • offers optimal, long-life insulation with no drawbacks, maintenance or repairs
  • enhances the value of property and the quality of life
  • leads to large energy savings and reduced heating costs
  • is cost-effective and easy to install

Insulation, what is it?

  • PDF

Insulation , simply put, is a quality of a substance to 'resist' transferring heat (or cold, basically energy) through it. In building construction high insulation is used to allow the internal environment temperature to maintain constant independently of external temperature changes. This not only makes the inside a more 'pleasant' place to live, it helps reduce heating and cooling costs my making it easier to keep at the same temperature; which in turn means your home is more ecologically friendly, as you are consuming less environmental resources.
