Will radiant barrier foil work with the fans we have installed?

Yes, the fan is basically just pushing air around the warehouse. When you install WarehouseFoil™ do so in such a way that you have plenty of vents (holes) in it to allow the air to be pushed out of the space.
WarehouseFoil™ is not intended to be installed airtight; if you install the foil so that the air being pushed into the building still has a path to the exhaust vents, then it can still get out and the fan will work fine. Read this for more info: Basic Warehouse Ventilation.
