Looking to expand your window and door vocabulary or impress your friends with a new industry term?

Derived from the Latin word fenestra, which means windows, fenestration refers to any opening in a structure, including windows, doors, skylights, vents, wall panels, storefronts, curtain walls and more. Associations such as Fenestration Canada and the National Fenestration Rating Council help keep the bar high for window and door building and material standards by providing information, resources and industry support. Ask your JELD-WEN representative about how we can help you meet your fenestration needs with high-quality windows, doors and accessories.
