Buy good quality high insulation and durable and low price PIR Polyisocyanurate Sandwich Panels for roof and wall applications. Polyisocyanurate also called PIR, polyiso, or ISO, is a thermoset plastic Manufacturered as a foam and used as rigid thermal insulation.


It has high proportion of methylene diphenyl diisocyanate (MDI) and a polyester-derived polyol is used in the reaction instead of a polyether polyol.


PIR is typically produced as a foam and used as rigid thermal insulation. Its thermal conductivity is below (0.023 W/(m·K)). PIR sandwich wall / roof panel or Polyisocyanurate sandwich wall panel with Polyisocyanurate foam has high heat insulation properties and good mecahnical load and high wind speed load bearing capacity.


PIR sandwich wall panel or Polyisocyanurate sandwich wall panel are composed of 3 layers, the external and internal are two coated Galvanized or Aluminum corrugated plates, and core high-density polyisocyanurate foam. Thanks to their properties the panels may be applied in the object that requires very high fire resistance, PIR sandwich panel is the most effective acoustic materials used in construction.


PIR cold storage room panel is a kind of board used for enclosing structures, which has good heat insulation and higher intensity.


It can reduce the heat transmission caused by difference in the internal and external temperature, and get to maximum efficiency of freezing and refrigeration systems.


Heat insulation material for lower construction cost. Panels are in multiple varieties and specifications to meet the need of various sites and projects.

The features of PIR insulation panel: Good heat conductivity, great water absorption, good in temperature preservation performance, excellent compressive strength and tensile strength, not easy to deformation, it is widely used in maintaining the combination of cold storage structure.

It can be widely used as the structural material and heatproof material in petroleum industry, chemical industry, construction, packing, refrigeration, military industry, space industry, aviation, transportation, industrial model design and so on.


1. Heat and sound insulation. Temperature suitable for PIR ranges from -200 centigrade to 150 centigrade.
2. Good chemical resistance, waterproof, anti-corrosion, insect-free etc.
3. Advanced Tech: Automatic rolling machines make the whole process of manufacture effective.
4. Energy conservation, environmental protection, economical, heat insulting, good structure, easy-doing construction
5. Light weight enough to reduce building expense.
6. Time can be saved on a building project due to the simple installation.
