We are sorry you are disappointed with the window chosen. While we don’t like to hear of unhappy customers, this is an opportunity for other potential customers understand the window options and choose the appropriate window for their need. Wrought iron window designs are acrylic. Acrylic windows are not able to be insulated because air cannot be completely sealed between panes of acrylic, unlike glass. We do however offer several true insulated glass window options. Many of these options complement our entry doors. We encourage everyone that has questions about our windows or complementary entry doors to visit www.clopaydoor.com to learn more.
