Knauf ECOBATT R-21 15 In. x 93 In. High Density Unfaced Fiberglass Insulation

Knauf insulation EcoBatt insulation are thermal and acoustical products made from highly resilient, inorganic glass fibers bonded by a thermosetting resin.

High density (HD) batts are available where optimal thermal performance is required and space for insulation is limited.

High-density cathedral ceiling batts, for example, deliver greater R-value in less space, so builders can increase R-values and still maintain adequate space for ventilation.
