IB Roof Systems just released an in-depth study that examines which is more efficient to install: wide PVC rolls or narrow PVC rolls. If numbers and data aren't your speed, IB Roof Systems will be having a weightlifter in their IRE booth on February 6 & 7 lifting 500 lbs to show how unreasonable it is for wide width PVC rolls to weigh that much. Our booth is #5921, the powerlifter will be lifting every hour on the hour, so make sure to stop by!
