Knauf Insulation Atmosphere duct wrap with Ecose technology is a thermal and acoustical insulation blanket made from highly resilient, inorganic glass mineral wool bonded by Ecose technology. It is available unfaced, with a FSK jacket and with a white metalized PSK jacket. Vapor retarders provide a 2 in staple flange on one edge and the factory applied facing assures uniform quality.
- Low K factor significantly reduces heat gain or loss when applied with proper compression
- Flexible and lightweight
- Excellent acoustical properties
- Tough and resilient
- Energy conservation which lowers operating costs
- System efficiency increases energy usage/costs decrease
- Conforms easily to flat or irregular surfaces
- Rolls allow for faster installation, lower labor costs
- Reduces sound transmission through the duct wall
- Assured condensation control when installed at proper thickness using FSK or PSK facings, proper installation and sealed joints, seams and penetrations
- Resists damage in shipment and during and after installation
- Low emitting for indoor air quality considerations
