Bio-solubility
The formulation used for Climacoustic ® insulation has been independently assessed to meet the requirements of the stringent Note Q standard (and is therefore
consistent with the highest Australian and New Zealand industry standards), and also assessed by Knauf Insulation against the criteria of the Australian Safety and
Compensation Council ASCC Approved Criteria for Classifying Hazardous Substances [NOHSC: 1008 3rd Edition]. As a result of this assessment, Climacoustic ®
insulation is not classified as hazardous according to the NOHSC criteria.
Superior Handling
• Highly resilient insulation recovers quickly to full thickness for a snug fit and superior finished aesthetics.
• Consistent quality materials feel good, cut easily and install fast.
• Low dust for easier handling and increased productivity.
Durability
• Climacoustic ® External Duct wrap is odourless, rot proof, non-hygroscopic, does not sustain vermin and will not encourage the growth of fungi, mould or
bacteria.
Proven Performance
• Preferred by professional installers concerned with quality, appearance and productivity.
• Excellent acoustical properties reduce sound transmission.
Superior Service and Support
• Knauf Insulation is totally focused on providing first class customer service, producing high quality product and ‘on time in full’ deliveries.
• Knauf Insulation supports a professional network of distributors and re-sellers in order to service a growing insulation market.

Storage
• Protect material from water damage or other abuse. Cartons are not designed for outside storage. Vacuum packaged material can be stored outside if care is
taken not to puncture the poly bag.
Preparation
• Install Climacoustic ® External Duct wrap over clean, dry sheet metal ducts.
• All sheet metal joints and seams must be sealed to prevent air leakage from the duct.
Application
• Install Climacoustic ® External Duct wrap with facing to the outside to obtain specified R-Value using a maximum of 25% compression.
• Butt all insulation joints firmly together. Longitudinal seam of the vapour retarder must be overlapped a minimum of 50mm. A 50mm tab is provided for the
circumferential seam and must be overlapped.
• Where vapour retarder performance is necessary, all penetrations, joints, seams and damage to the facing should be sealed with an FSK, PSK or foil tape or
glass fabric and mastic prior to system start-up.
• Pressure sensitive tapes should be a minimum 75mm wide and be applied with moving pressure using an appropriate sealing tool. Staples should be outward
clinch and placed approximately 150mm on centre.
• For rectangular ducts over 600mm wide, secure the insulation to the bottom side of the duct with mechanical fasteners spaced on 450mm centers to reduce sag.
Care should be taken to avoid overcompressing the insulation with the retaining washer.
• It is neither necessary nor desirable to adhere duct wrap to duct surfaces with adhesive.
