Review on Design Engineering 050137 Deadening Headliner by Richard Sallah

This insulation is almost an inch thick and effectively eliminates heat radiation from above here in the Deep South. Once installed, the air conditioner can run on a low level all day with no contour. Small note - sunroof fronts have cutouts for some twist locks and others do not. Please note that the top will need to be removed to install the center panel as the die Insulation runs between the top and the soundbar. It is not possible to slide the mat into this limited space with the adhesive backing showing. It is also VERY IMPORTANT to position the m correctly before it touches the surface as the glue is very aggressive like tape when grabbing and holding. As soon as he grabs it, he's there. This is a recent installation, so there is no data on the adhesive's long-term performance in hot weather. I will update if it doesn't work.
