PUR vs. PIR: Know the Difference

  • by

Close loved ones share a family background, however seldom have the exact same individuality. Insulation is comparable in that PUR and also PIR are close in chemical composition however differ in efficiency. While their composition makes them various, some buildings that make them comparable are that they both are lightweight with high thermal conductivity, environmentally sustainable and also can be reused.

PUR foams are essentially made by reacting a “polyol” element and an “iso” part in which the OH groups of the polyol component chemically balance the NCO teams of the iso element and type urethane links. In PIR foams, the iso elements respond with each other in trimerization responses to create isocyanurates. Excess iso responds with polyol to develop urethane links too.

The development of PUR and PIR

PIR as well as PUR are both originated from polyurethane, a plastic product developed by German scientist Otto Bayer and his associates in 1937. In 1954, the unintended intro of water led to stiff polyurethane (PUR).

Just 13 years later in 1967, researchers surpassed PUR’s thermal stability and also flame resistance to produce polyisocyanurate (PIR). In order to develop the new kind of insulation, scientists caused a chain reaction at a higher temperature.

The benefits of PUR

PUR insulation can be injected into wall dental caries to create an energy effective obstacle. The foam has the ability to reach tiny rooms to develop an air-tight seal. According to the Insulation Producer Organization, PUR supplies “the very best thermal performance of all sensible complete dental caries insulants.”

PUR foam can be continuously sprayed onto any kind of kind of surface. It is generally much less costly than other materials, making it ideal for renovations.

In flood prone areas, PUR’s high water resistance can reduce the impact of water damage in wall surface dental caries, because it is a material that does not hold moisture.

The benefits of PIR

Regardless of PUR’s benefits, PIR insulation constructs upon them. PIR, commonly reduced into boards, can be used in shielded metal panels, wall cavities and also as protected plasterboard. PIR has such a high thermal performance, it requires just half the thickness of typical mineral-based insulation products.

PIR, like PUR, is understood for use as a low-moisture obstacle. One of the most notable setting apart aspect for PIR is its fire as well as smoke resistance. PIR slows down the spread of flames and also reduces the smoke released from the fire when contrasted to PUR products.

The future of insulation

While PIR as well as PUR have actually been used for decades, there’s an additional advanced insulation that outshines both in fire protection and thermal performance: Kingspan’s QuadCore Innovation.

With 11 percent much better thermal performance than PIR as well as approximately 60 percent improvement over PUR, it is unsurpassed out there. Its fire resistance fulfills the highest possible insurance policy as well as regulatory criteria.

As we remain to search for building solutions that are power effective, QuadCore is the newest generation of insulation modern technology in a household of development to maintain us safe, warm and also completely dry.
