Reflectix and furring strips are going up cleanly. Using 3M double-stick tape to secure the Reflectix to the van wall. I was going to lightly secure my Thinsulate to the panels but on realizing that the panels I'm putting up are only semi-permanent, I decided to just use the 3M spray adhesive to secure the Thinsulate. For time's sake so that we can get out exploring and find out what we do and don't like about certain layouts, we're just using the original panels and headliner that came with the van. I'm envisioning finalizing the interior next summer.
Reflectix and furring strips. The 2x2 on top of the wheel well was actually shortened to be the same length as the flat spot on the top of the wheel well.
Tucked Reflectix into the space behind the "crown molding interior ribbing."
Some strategic cut eliminated folds from bending flat stock into the corners.
Thinsulate was sprayed with 3M on the fuzzy side and Reflectix was sprayed as well. Wait 1 minute. Stick it up. Since I'm using the PO's headliner and panels, I couldn't really make a continuous inner shell of Thinsulate because I don't think I'd be able to get the original panelling up on the wall that way. Might try to do that when I finalize things next year.
I'm going to use sheet metal screws to attach the OEM headliner because I think the plastic rivets won't be strong enough or have enough bite to hold up against the extra insulation in place here. I left the upper metal ribs bare to make it easier to locate where to screw in to. I may or may not cover these in the future when I finalize design.
