## Description

Knauf Insulation Board with ECOSE Technology is a thermal and acoustical insulation product bonded with ECOSE Technology. It is available plain, with a factory-applied FSK facing, PSK (metalized polypropylene-scrim-kraft) or with a factory-applied all-service jacket (ASJ). ECOSE Technology ECOSE Technology is a revolutionary binder chemistry that makes Knauf Insulation products even more sustainable than ever. It is based on rapidly renewable bio-based materials rather than non-renewable petroleum-based chemicals traditionally used in glass mineral wool insulation products. ECOSE Technology reduces binder embodied energy and contains no phenol, formaldehyde, acrylics or artificial colors. Application Knauf Insulation Board with ECOSE Technology is a versatile product for thermal and acoustical applications such as: heating and air conditioning ducts, power and process equipment, boiler and stack installations, metal and masonry walls, wall and roof panel systems, curtain wall assemblies and cavity walls.
