Metal Building Insulation

Metal Building Insulation

Knauf Insulation Unfaced Metal Building Insulation with ECOSE® Technology is a resilient, flexible unfaced blanket insulation made from inorganic glass mineral wool bonded by ECOSE Technology. The blanket is suitable for application of facings and has sufficient tensile and bond strength for normal handling by the fabricator and contractor. The blanket may also be used unfaced as additional insulation to fill voids in wall and roofs of metal buildings.

ECOSE® Technology

ECOSE Technology is a revolutionary binder chemistry that makes Knauf Insulation products even more sustainable. 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 does not contain phenol, formaldehyde, acrylics or artificial colors.

Application

When Knauf Insulation Unfaced Metal Building Insulation is faced with a suitable vapor retarder, it can be installed in exterior wall and roof surfaces of pre-engineered buildings. The product may be used unfaced to fill voids in walls and roof cavities of pre-engineered buildings.

Glass Mineral Wool and Mold

Glass mineral wool 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. Air handling insulation used in the air stream must be discarded if exposed to water.

Notes

The chemical and physical properties of Knauf Insulation Unfaced Metal Building Insulation represent typical average values determined in accordance with accepted test methods. The data is supplied as a technical service and is subject to change without notice. References to numerical flame spread ratings are not intended to reflect hazards presented by these or any other materials under actual fire conditions.

Caution

If Knauf Insulation Unfaced Metal Building Insulation is compressed beyond a 5:1 ratio during or after lamination, the product can be damaged. Check with your Knauf Insulation sales representative to assure information is current.
