Fenex sales person sold me what he called triple glazed 16” window pane windows that would reduce outside noise completely. They are not. Right after the installation the noise level increased like never before. One window cracked with the cold and upon examination, the two outer glass panes seem to be approximately 3 mm in thickness, with a paper thin laminate in between, which cannot resist our Ottawa winters. Since 2013 we have had approximately SIX windows replaced for the same issue: condensation inside the window panes. It has been extremely inconvenient dealing with defective/cheap windows year after year for seven years! Fenex continues replacing bad windows with bad windows, until the warranty runs out, and then, I will be forced to pay the full amount to replace their poor quality windows with another company with quality windows, thus losing thousands of dollars! This is substandard customer service. After seven years of being patient with this company and the ongoing window issues, I do not recommend this company to anyone.
