Elaminator® 300 Series Insulation System

ELAMINATOR® provides a High-R application for new construction without support wires or structures below. The ELAMINATOR® system reduces the compression above the purlins, because the first layer of insulation is installed between the purlins. A layer of backfill insulation is placed over the purlins to ensure complete coverage by the insulation.
