Step 31: Insulate the roof


After the headliner is installed, you can start to glue in your insulation.  I used about a 2 inch of rigid foam. 

On the curves I used a base of 3/4 inch foam, kerfed with a utility knife so it would fold.  I used Titebond II to glue it down.  I then used 1/4 sheets (usually three) to fill in the rest of the space.  Also glued with TB II. 

I used a variety of nails and strips of material to hold it all into place.

you can also use PL 3000 that is especially made for the foam insulation board, Works well and has a tiny bit of flex in it for weather changes. I use it on foam carvings for sets.
