The thickness is almost half of the specs.
The thickness is almost half of the specified thickness. I ordered 5 rolls from Isover and they all had the same issue. On the packing it said 7cm, but in reality it's about 4cm, even after a day of rest. I would never buy from such a company again. Now I'm forced to close off the roof with less insulation than planned, because of their misinformation.
