Good duct insulation

Monday, May 09, 2011

Material is easily handled. It is not rigid and collapses on itself for storage. They ship it in box longer than 6', but the product could easily be folded to save a considerable amount on their shipping cost (customer's shipping cost was free at time of my purchase, so this is Drillspot's loss that they do not seem to pass onto customer because they offer the material at a very competitive price). We're using it as duct insulation on a forced air diesel heater in our boat. The ducting was already installed, so we needed to slit this material, wrap it around the duct, and tape it closed. We used the 3M 3903 Duct Tape to seal the seam, which worked great. It was a straight forward job. The material was not too smelly, and clean-up was non-existant. The material outgases slightly on first use to a high temperature - it wasn't stinky, it just seemed a little smokey in the area. After that first outgassing, the material seems stable and non-smelly. Before we installed this material, the ducting was so hot you could not touch it. Now that it is insulated, you can lay your hand on the insulation and it feels slightly warm. Definitely does the job. In our application, the ducting reaches ~240F near heater, and this material is rated to only 220F. We did some rough tests and discovered the material seems OK at the higher temperature - it does not smoke or burn. When we reached around 350F in the test, the material got "cripsy" but still no combustion or melting. Still hesistant to use long term at a temp higher than rated - but this is our problem, not the product's fault. We didn't realize the ducting would get that hot once insulated.

Easy to use, effective insulation, closed cell so will not absorb moisture and get moldy

Ship in more suitable sized container, a 6' piece could easy folded to fit in a 1-2' box.
