Tools needed for Installation

Straining wires, G-clamps, Galvanized hoop irons, Pop rivets, Drill, Heavy duty staple gun, 10mm wire staples.

Installation Instructions

  1. When installing the blanket in new buildings over purlins ensure that the straining wires are placed 300mm apart.
  2. Affix to the roof apex and unroll the blanket longitudinally taking out any slack and attach to the bottom purlin.
  3. To join the blankets fold up the overlapping foil edges and staple, fold the join over and staple again.
  4. Precaution to be taken when installing in windy conditions.

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.
