  2. All portions of duct designated to receive ductwrap shall be completely covered with duct wrap.
  3. Install Ductwrap with the facing showing, butting the adjacent rolls tightly together, utilizing the 100 mm facing overlap to ensure an adequate seal.
  4. Seams and joints shall be sealed with pressuresensitive tape matching the insulation facing.
  5. Where rectangular ducts are 600 mm in width or greater, ductwrap insulation shall be additionally secured with strapping at 300 mm centers.
  6. Where a vapour barrier is required; seal all tears, punctures and other penetrations of the ductwrap facing.
HANDLING & STORAGE
Store product undercover, and in dry conditions. Store flat. Handle with care, especially on the edges and corners, which can be damaged if subject to sharp or heavy impact. Do not apply excessive pressure, for example by standing or sitting on the product, as permanent damage may be caused.
