Knauf Insulation Earthwool Insulation Board 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. It is bonded with ECOSE Technology and is available plain or with a factory applied foil-scrim-kraft (FSK) facing or all-service jacket (ASJ+).

ECOSE Technology is a revolutionary binder chemistry that enhances the sustainability of our products. The "binder" is the bond that holds our glass mineral wool product together and gives the product its shape and brown color. ECOSE Technology is a plant-based, sustainable chemistry that replaces the phenol/formaldehyde (PF) binder traditionally used in glass mineral wool products. Products using ECOSE Technology are formaldehyde-free and have reduced global warming potential when compared to our products of the past.

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.

Features

• Energy Efficient - Excellent thermal efficiency results in lower operating costs
• Low-Cost Installation - Lightweight, easy to handle and fabricate, and Fast, easy installation lowers labor costs
• Health & Safety - Low emitting for indoor air quality considerations
• Significant Acoustical Benefits - Excellent acoustical properties effectively reduce noise
• Polished Appearance - FSK and ASJ+ vapor-retardant facings provide a neat finished appearance

Applications

• All insulation joints must be firmly butted. Insulation can be secured with mechanical fasteners or banded. Minimum compression is to be used to assure firm fit and still maintain thermal performance.
• Vapor retarders should overlap a minimum of 2" (51 mm) at all seams, and be sealed with appropriate pressure sensitive tape or mastic. When applying pressure sensitive tapes, the tape must be firmly rubbed with a proper sealing tool to make sure the closure is secure. Follow tape manufacturer’s recommendations.
• Fasteners shall be located a maximum of 3" (76 mm) from each edge and spaced no greater than 12" (457 mm) on center.
• Where vapor retarder performance is necessary, all penetrations and facing damage shall be repaired with tapes or mastic with a minimum of 2" (51 mm) overlap. Tapes should be applied using a sealing tool and moving pressure. Use on ducts, plenums, vessels, tanks and equipment operating at temperatures of 450° F (232° C) or less.
• Tapes and mastics (dry) should have a UL 723 rating of 25 flame spread, 50 smoke developed.
