Polyisocyanurate Pipe Covering

Polyisocyanurate (“polyiso”) pipe covering is a closed-cell rigid foam insulation with low density and low water and vapor absorption designed to fit over and protect pipes and equipment. Polyiso pipe insulation provides thermal performance, fire protection, and moisture resistance for commercial and industrial applications. Polyiso pipe covering can be fabricated as plain or in a number of different jacketing options. View our selection of polyisocyanurate pipe coverings below!
