Then come up to a height of your grill and wrap the Reflectix around the vertical posts on the "x" frame sitting under your grill. The CPVC setup would keep the material away from your grill's surface and provide a "windbreak". You could then fashion a Reflectix cover. Of course If your grill is the size of a 1/4 acre lot then this would not be feasible. You can see my set up here:
Actually, this is what I ended up finding today as well. My local Lowe's didn't have the denim insulation, only the fiberglass stuff. So, thinking that I can make the reflectix work, I bought some velcro as well. My plan was to make "panels" for each side of the lid and velcro them together so I can pull it apart if need be (and in a hurry at that if that stuff somehow caught fire). The stuff is Class A /Class 1 fire rated so I thought it should be OK wrapping at least the lid directly touching the lid...
