Elastomeric insulation is a closed-cell foam insulation that provides moisture resistance and steady, long-term thermal performance. Closed cell elastomeric foam has strong water vapor permeability, eliminating the need for a vapor barrier to prevent moisture transfer. Its closed-cell structure prevents moisture wicking, attenuates HVAC noise, and dampens mechanical vibrations. Elastomeric foam is commonly used as pipe insulation and is available in a wide range of shapes and thicknesses. Polyethylene insulation is a closed-cell, lightweight, thermoplastic insulation. Its high dielectric strength and very low electric conductivity make it an excellent insulator. Elastomeric and polyethylene insulation can both be used in industrial and mechanical applications.
