Foam Insulation Under Cab for heat??

Hello Campers! Took my RV to a local HIGHLY recommended shop to get their opinion about the poor airflow in my 2007 Ford E450 Winnie Outlook. He said that he has seen rigs come in with Spray Insulation under the cab area...under the cab. He said he sees it once in a while when he puts the RV up on the rack. WHAT A GREAT IDEA! SPRAY FOAM INSULATION 'UNDER' THE CAB AREA - UNDER THE FLOOR BOARD THAT GETS SO HOT! Question is now, what type of business do I call regarding that type of work? Does anyone out there have info or experience spray foaming the underside of their cab area for engine/header heat insulation? I would love to know!

they told me they saw it applied directly under cab area to keep the heat from coming up through the floor.

Your not talking around the engine compartment are you? Because if it gets that hot what's it going to do to the foam? Most foams tend to melt in high heat situations.
