ActivWall’s Horizontal Folding Door is made of thermally broken aluminum with insulated glass for high energy efficiency. It is used to open up an extension of the living room to an adjacent screened porch, both of which were added to the home after the initial construction. The custom five-panel door measures 176″ wide by 100.25″ high and is finished in black powder-coat with a U-Channel sill. The timeless style of this product and multiple finish options allow it to fit in with almost any architectural style.
