I heard about this product not too long ago, and I found it intriguing. It’s from Therma-Tru Doors, a Maumee, Ohio-based company that produces steel and fiberglass entry and patio doors. One of its newest products is a fiberglass entry door with vented sidelites, which means that a homeowner is able open the sides for fresh air. The company says the product is a continuous system that consists of either one hinged door and two hinged sidelites, or two hinged French doors and two hinged sidelites. www.thermatru.com.
