Asahi Fiber Glass aclear Aclear Mat Density 10K Thickness 50mm x Width 430mm x 2880mm Set of 5 I bought these for ceiling insulation in a Hiace, but I bought too many. 4 sheets were enough for the narrow ceiling. I think one sheet would be enough for the sides. I will roll them up and pack them in cardboard for shipping. I have sold two sets so far, so this will be the last time I sell them as a set. Thank you.
