Long Radius

Polyisocyanurate (“polyiso”) long radius elbows are made of preformed polyiso insulation that is designed to fit over long radius pipe fittings. Polyiso insulation is a rigid, closed-cell thermal insulation that has a low density and low water and vapor absorption. It can be used in both commercial and industrial applications and in temperatures ranging from -100°F to 250°F. Polyisocyanurate long radius elbows feature a moisture-resistant core and provide excellent fire protection. Polyiso long radius elbows can be fabricated as 90 and 45 degree elbows.
