Knauf Wall and Ceiling Liner M with ECOSE® Technology

Description

Knauf Wall and Ceiling Liner M with ECOSE Technology is a black flexible fiber glass blanket with a black mat facing adhered to one surface. It provides thermal and acoustical insulation and a visual barrier. Its smooth, tough surface resists damage during installation.

ECOSE® Technology

ECOSE Technology is a revolutionary new binder based on rapidly renewable bio-based materials rather than non-renewable petroleum-based chemicals such as phenol, formaldehyde or acrylics. ECOSE Technology reduces Knauf binder embodied energy and contains no phenol, formaldehyde, acrylics or artificial colors found in traditional fiber
glass insulation.

Application

Knauf Wall and Ceiling Liner M with ECOSE Technology is designed for use as an acoustical and visual barrier for walls and ceilings where a black surface is required. It is primarily used in theaters, sound studios, public concourses and other areas where acoustical treatment is needed. It is intended to be mechanically fastened to walls and covered with fabric or draping, or suspended above linear metal and metal pan ceiling systems to serve as both a visual and acoustical treatment.

Features and Benefits

Acoustical Barrier

Reduces airborne sound.
Significantly improves STC ratings of wall configurations.

Fiber Glass and Mold

Fiber glass (glasswool) insulation will not sustain mold growth. However, mold can grow on almost any material when it becomes wet and contaminated. Carefully inspect any insulation that has been exposed to water. If it shows any sign of mold it must be discarded. If the material is wet but shows no evidence of mold, it should be dried rapidly and thoroughly. If it shows signs of facing degradation from wetting, it should be replaced.
