What is an insert? A fireplace insert is a unit that is installed in an existing fireplace to give it a facelift. Fireplace Xtrordinair offers four models of deluxe premium gas fireplace inserts, with dozens of beautiful designer faces and fireback combinations to choose from. While every one of these inserts embodies the same attention to detail in design and construction, each insert is unique. Sizing and heating capacities range from medium to large heaters. Here are just a handful of products from the Fireplace Xtrordinair line. Give us a call, e-mail us, or stop by our showroom to learn more!
