We have been using Expanding Foam packaging with heavy gauge corrugated for over 30 years. This method of packaging forms perfectly to the kiln. It protects the kiln from impact and prevents the kiln from shifting within the box. This means fewer freight claims which we all know can be a severe time drain. If there is a freight claim you can be assured that it will not be declined due to improper packaging. Our HotStart Kilns are packed in extra heavy gauge boxes so we can ship them via UPS with no worries.
