Zola’s Tilt & Turn windows are often speced for Passive Houses, the company says, because they are so energy efficient. Specially designed hardware enables the sashes to swing or tilt in with the turn of a handle. Sashes can be double or triple glazed, in sizes as large as 5 feet wide. The windows come factory finished in a range of stain or paint colors. Aluminum cladding is also available. Prices run from $35 to $75 per square foot.
