Topway® Steel is dedicated to technologies and methods of building a low carbon world. Topway® Steel PIR Insulated Panel and PUR Insulated Panel System with the industry’s most thermally efficient core, better energy efficiency, fire safety weather resilience, health, and aesthetics, is a gift to our world, and make sure our children’s better future.
PIR Insulated Panel or Polyisocyanurate Insulated Panel are composed of 3 layers, the top layer and bottom layer are corrugated coated Galvanized Steel, stainless steel or Aluminum sheet, and the core is high-density polyisocyanurate foam. Polyisocyanurate also referred to as PIR, polyiso, or ISO is a thermoset plastic typically produced as a foam and used as rigid thermal insulation.
The starting materials of Polyisocyanurate (PIR) are similar to those used in polyurethane (PUR) except that the proportion of methylene diphenyl diisocyanate (MDI) is higher and a polyester-derived polyol is used in the reaction instead of a polyether polyol. The resulting chemical structure is significantly different, with the isocyanate groups on the MDI trimerising to form isocyanurate groups which the polyols link together, giving a complex polymeric structure.
PIR insulated panel or Polyisocyanurate insulated panel is applied as external walls and internal division walls, installed vertically or horizontally on single or multi-span structure. Such as Industrial buildings, Steel frame structure buildings, Storehouses, and logistic centers, Commercial buildings and offices, Fire Rated Buildings, Agricultural objects, Sports halls, Logistics centers.
