In October 2009 we purchased a $1900 supposedly energy efficient sliding door from Peachtree. We have had trouble with this door ever since. It has constant air leakage to the point of the door tracks freezing with an inch of ice. Peachtree has sent numerous technicians out but none of them has kept the cold freezing air from infiltrating our home. We have to keep flannel sheets at the bottom of the doors to help keep the heat in. We’ve also had to tape all the seams of this malfunctioning sliding door or the frigid air just penetrates our entire home.
