The van has three windows in the cargo area.  The slider and two back door windows. In order to reduce heat loss/gain and for privacy Relectix inserts were made to cover the glass. On the Transit there are slots between the glass and the metal door fame. The Reflectix thickness is correct to fit in the slots. Cut a cardboard pattern of each window opening. The two rear windows are not the same size. Using a marker pen the slot locations were marked on the cardboard. In some locations the slots are continuous and in other locations just a short opening. Added tabs to the pattern where the slots were located. The tabs extend out about 1" into the slots. Used Reflectix silver tape to seal the edges of the Reflectix tabs. Covers are easy to install and remove. They are stored behind the Murphy bed panels.
