Notes;
• Make a list of all duct to be wrapped prior to starting and have ALL tools and material required to wrap pipe. You would be surprised at how much time is lost running back and forth to the truck.
• Try to wrap in long lengths to avoid seems and save time (confirm larger sections can physically make it to their intended locations)
• Always connect reducers, end caps and even elbows prior to wrapping to save time
• Do it right the first time! Quality is important AND your reputation is ALWAYS on the line!
