Retailers such as The Home Depot, Lowe's and Amazon.com sell fireplace screens as of 2015. Smaller retailers that specialize in chimneys and fireplaces also sell fireplace screens and may have brick and mortar stores; however, they may not have websites.
The Home Depot's website lists available fireplace screens in the Fireplace Screens section. Fireplace screens listed on The Home Depot's website have one to fours panels, come in several different decorating styles, and range largely in price. Screens with panels and hinges allow the screen to adjust to the size of fireplaces. Some fireplace screens feature doors for easy access.
