Polyisocyanurate Curved Segments

Polyisocyanurate (“polyiso”) curved segments are a closed-cell rigid foam insulation that has been cut on a curvature to match the radius of a large-diameter pipe or vessel. Polyiso insulation has a low density and low water and vapor absorption, offering excellent thermal performance and inherent fire resistance. Polyiso curved segments can be used in both commercial and industrial applications with service temperatures ranging from -100°F to 250°F. Curved segments can be fabricated for pipe sizes beginning at 18”, plain or jacketed. Browse our selection of polyiso curved segments below!
