Polyisocyanurate (/ ˌpɒlɪˌaɪsoʊsaɪˈænjʊəreɪt /), also referred to as PIR, polyol, or ISO, is a thermoset plastic [1] typically produced as a foam and used as rigid thermal insulation.

Polyisocyanurate is another option, coming in as the densest and most expensive option for foam board. Typically sold as sheet insulation in a standard size of 4 feet by 8 feet, foam insulation panels can help you reduce energy costs, get a handle on moisture control and more.

TRYMER PIR (polyisocyanurate) is a closed-cell, foam insulation for industrial pipes, vessels, and equipment. TRYMER PIR can be used in applications that operate at temperatures ranging from -297°F to 300°F (-183°C to 148°C).

2021年7月28日 · When building or renovating a high-performance building envelope there are really three main kinds of rigid foam panels you are going to have to choose from - Polyisocyanurate known as Polyiso (PIR), Extruded Polystyrene (XPS) - often called Styrofoam - and Expanded Polystyrene (EPS).

PIR (polyisocyanurate), typically cut into boards, can be used in insulated metal panels, wall cavities and as insulated plasterboard. PIR has such a high thermal performance, it requires only half the thickness of other mineral-based insulation products. PIR, like PUR, is known for use as a low-moisture barrier.

2020年10月7日 · Polyisocyanurate thermal insulation, commonly referred to as polyiso, has proven to be popular due to a combination of its cost effectiveness (i.e. cost per insulation unit), efficiency (i.e. insulation value per unit thickness), and fire resistance, as compared to some competitive materials.

POLYISO is most commonly used as a continuous insulation for roofs and walls, and as a protective roof cover board. POLYISO’s unique chemistry delivers industry-leading R-value and fire performance. A variety of product types make POLYISO the ideal solution for continuous insulation applications.

Polyisocyanurate boards (also known as PIR or polyiso) and rigid polyurethane foam are highly durable and best-in-class options for thermal insulation in the construction industry and in appliances.

Polyiso, or polyisocyanurate, is a rigid foam insulation used in more than 70% of commercial roof construction and offers a continuous insulation solution for commercial flat (low slope) roof insulation and wall assemblies.

2008年1月1日 · Polyisocyanurate insulation is widely used in the mechanical and industrial insulation industry. Because of some fundamental chemistry changes, it is now filling the needs as a core material in composite panels.
