FACTORY LINERS ARE (not) FINE
Leaving OEM liners in your van can feel like a simple costs saving; that is, until they fail when you need them the most. DuraTherm can take the hits.

Protect your vehicle image and resale value.
Naked metal walls are easy to dent and damage.
Dented walls means lost resale value, an unprofessional brand image, and potentially exterior vehicle rust.
DuraTherm eliminates the risk and preserves the residual value of your vans.
Keep your cargo area cool.
DuraTherm Ceiling Liners are designed to preserve the internal temperature of your cargo area and deflect direct external sunlight.
Unprotected vehicles run the risk of extreme temperature fluctuations, which can often result in moisture build-up, overheating, and unsafe operator conditions.

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.
