Elastomeric foam insulation is a rubber-based insulation for HVAC, refrigeration and plumbing applications. This thermal insulation is flexible and made with a closed-cell material. EPDM pipe insulation offers condensation control by providing excellent moisture vapor resistance, thermal conductivity, and flexibility. These features make it perfectly suited for refrigerant lines, cold-water plumbing, and chilled-water systems. DI offers elastomeric insulation products such as pipe coverings, tapes, sheets, duct liners, and more. Browse our selection of elastomeric insulation below.
