Answer This Question

A:  Very flexible, you can turn it 180 on itself and it will stay snug against itself on the inside curve. You could fit a curve into about 1 1/2- 2 feet of space.It’s also fairly collapsible so you can fold it onto itself and kind of smush it into a space and still maintain airflow.

    Q:You can use it for mobile home

    Answer This Question

    A:  Hello Yidier, The KP is not coded to be used for a mobile home application. You would need to look at the RKD product for your needs. The outer jacket on the RKD has a thicker mylar allowing for such an application for mobile home installation. Thanks, Thermaflex

          Good solution for insulated duct
          This was a good solution for the insulated duct that I needed to replace for one that was damaged, was identical to the one replaced. The company was smart to display the company and product on the duct, made it easy to choose the replacement.

            Easy to use. Outer skin is durable, was able to drag it across rafters without tearing. Ships compressed in a relatively small box. Tip - Place box close to duct run then open box end and feed it out.
