After our meeting with Timothy, a salesperson for Quality First Home Improvement, we were educated on all the benefits of triple pane windows. They're made of three panes of glass, rather than just two, and are the epitome of energy efficiency, sound reduction, and condensation resistance. My wife and I value interior home comfort, and purchased seven, high performance triple pane windows! The day of the project the installers arrived as scheduled, and did a very professional job! "Our experience working with the entire team from Quality First was exceptional!"
