DuraTherm door liners are made from the same durable plastic as the DuraTherm wall liner, adding extra protection, insulation and sound deadening in the vehicle.

Available in white and grey in color, Legend has these door liners available for most cargo vans on the market.

DuraTherm door liners protect the sheet metal or the glass in the window cavities from moving objects inside the van that could cause potential damage, such as dents or broken windows.


Yes, you can! Legend liners and floors are moisture and mildew-resistant, meaning they won’t rot or break down like a factory mat or plywood will over time with moisture. The surfaces are very easy to clean - we recommend using a cloth and water. Hear this upfitter talk about washability of Legend products and watch this technician clean the walls and comment how nice they are to clean.

Absolutely! Upfitters all over install their preferred shelving once the Legend floor & walls are installed. Not only are they compatible to be drilled through to secure the shelving, it’s recommended, because it gives a backing to the shelves so that no cargo or tools fall into the metal cavities and are lost forever!

Short Answer: Roughly R7.5.

Insulated DuraTherm itself has about an R-Value of 4.5, not installed.

When installed, the gap between the wall and the factory metal van wall contributes a further R3 rating, due to the gap between the two creating a “barrier”, providing further insulation.
