The experience was not what I expected. Ordered was the Corning R38 - 24x48 bats. The aroma that came from the bats made the entire family sick . . . . . it was so bad that we had to put all the bats outside of the garage as it was causing burning eyes, and respiratory issues with the family. On top of all that they shorted the order by ONE bat - $72.10 may not seem a lot to most but this was our Thanksgiving Day meal budget and the company "Insulation 4US" has yet to acknowledge the short even though pictures were sent to Garry . . . . So with this shorted product - there was no savings - if I were to do again I would definatley buy local and cut out this middle man.
