reflextics - well the shiny bubble wrap type stuff

[Nissi]

Light comes in our van and reflects all over the place from the reflextics - I'd prefer it to be darker at night. The outside is ok but I just encased the reflextics in fabric to hold it all together.

I am at a loss with your statement here. Probably just me...

For the cab area of my Nissan Cargo Van I cut reflextic to fit snugly over the window.
NO light comes in here, day or night.
For the front (very large window) I cut a slot in the reflextic to go around the rear view
mirror. And the front window visors hold the reflextic in place.

I could have cut this piece a little longer (up and down), but even not being as
snug a fit as the side windows there is very little light that gets in or is seen on the outside
from inside the van.

When I put in one side window where the sun is shining, have the other window open a bit,
and the front window covered there is a HUGE drop in the amount of heat coming into the van.
