Rubber Liner

Fiber-free closed cell elastomeric thermal and acoustical duct liner is engineered to safeguard IAQ, attenuate HVAC noise, and reduce energy loss.

Often specified hospitals or medical facilities, schools, labs and jobs that engineer desires the acoustic benefits of internally lined Duct but the intent of a fiber free interior.

Sometimes to reduce cost, the engineer will specify Elastomeric from the air handler and out 30 ft, and then bare duct with wrap on the rest of the run. Conklin stocks 1″ x 59″/60″ X 50 ft Non adhesive backed as standard.
