Thermal Barrier - Insulated Wall Liners

March 2019 - In harshly cold, snowy Minnesota, Legend distributor Stonebrooke Equipment put Legend Insulated DuraTherm to the ultimate test, to see if the insulation and material makes a difference in such harsh weather. We wanted to prove the power of
DuraTherm’s insulation and illustrate how it can help your cargo van fleets create a more temperature controlled interior. 

Step 1 - upfit ProMaster #1, a 136" WB with Legend complete kit including Insulated DuraTherm Wall, Ceiling, and Door liners, StabiliGrip Rigid Flooring, and Aluminium Sill Plates. This was to be the van that should hold the heat in, and prove its thermal barrier. 

Step 2 - get the ProMaster #2, also a 136" WB, and leave it empty. Are liners really necessary when insulating a van is of high priority? 


Step 3 - park the ProMasters in the snowy parking lot, shut the doors, and turn them on. See the results below. 

Insulation Barrier Test2-2

As seen in the results above, the van with no wall liners at all couldn't hold a candle to the van with Insulated DuraTherm. 

The empty van took over twice as long to heat up to room temperature, because so much heat was being lost through the bare van panels. The van with wall panels was able to get up to a temperature significantly higher than the empty van. Then when the vans were shut off, the van without liners went back to an interior temperature below freezing in only 2.5 hours, while the van with the liner was still at 47° after 4.5 hours. 

Legend continues to test our products so we can provide valuable proof of yet another reason why Insulated DuraTherm is more than necessary in a cargo van upfit.
