SmartSHIELD Plus - XPE Foam + Glue - Thickness: 10mm

I used the foam board on the ceiling of my gazebo. Heat was too much in the summer so I added the foam board. Foam board is good quality and does keep the heat out. The glue was the problem. After a couple of hours, I was horrified to see my 15' x 25' gazebo ceiling littered with hanging foam board. I had to buy spray glue to make them stay (along with some gorilla (not duct) tape). I'm not sure if the foam board is made to hang, if so, it doesn't do a good job at all. Right temp, applied as instructed...didn't work. Material is awesome, though. I'd still recommend this product with spray glue.
