Knauf Insulation B16E R30K Insulation, 48 in L, 16 in W, R30 R-Value, Fiberglass, Natural Brown

Knauf EcoBatt Insulation doesn't look like any insulation you've ever seen, that's because its natural brown color represents a level of sustainability never before achieved. The color comes from ECOSE Technology, a revolutionary, new sustainable binder. Made from rapidly renewable organic materials rather than petroleum-based chemicals commonly used in other insulation products. ECOSE Technology reduces binder embodied energy by up to 70% and does not contain phenol, formaldehyde, acrylics or artificial colors used to make traditional fiberglass insulation. EcoBatt Insulation combines sand, post-consumer recycled bottle glass and ECOSE Technology to create the next generation of sustainable insulation.
