Teaser pics, in progress DIY project, driver side installed with 3M tape; testing how that holds in 108 temp today and over the weekend.
Two data points with infrared temp meter:
Outside temp 107, ambient inside temp in cabin with air cond on was 89, measuring door panels.
The new liner over driver side measured 100 degrees
Passenger side no liner 136 degrees on the large flat parts, and 156 degrees in the thin highest channels.
30 minutes driving later, 108 outside, parked 5 under partial shade,
ambient cabin temp is 95 on door panels
New liner measured 96 degrees
Passenger side no liner measured 125 degrees, 139 in the highest channels
What I liked about this test is there is not the hot cloud feeling overhead and liner temp is close to cabin ambient, measured at shoulder of door panels and steering wheel.
I tested an exotic aerogel prototype last week, but not seeing that worth the effort.
This liner is simple canvas stitched over two layers of reflective foam and attached with 1/4 thick velco like tape, that lifts the liner away from the roof by the 1/4 inch for air space.
The weight is ounces, foam and cloth.
The second surprise feature was with first drive test and not seeing white overhead, as the liner covers the sides and to the visor, less overhead contrast visually.
Happy with the results. Will be in DIY topic with materials and construction photos in a few days when passenger liner is stitched and can post a link back here if anyone is interested.
