Aluminum Mylar Radiant Barrier stops the transfer of hot and cold temperature keeping the cab and bunk temps regulated


Doesn’t black facing outside retain heat? In short yes black is the hottest color, but our Ultraflect™ black nylon is one of the “coldest” black fabrics on the market. It retains very little heat, and with the added layers of insulation along with the Mylar barrier the outdoor Sun will not penetrate into the cab.
