Dual-Turn Windows Our Dual-Turn windows are a great way to add style to your home, and are much like our tilt-turn windows but with a more classic look. Both sashes swing inwards to provide easy cleaning, and also come with the option of a side-hung sash for easy escape in case of an emergency. Our dual-turn windows also have key-locking handles for higher levels of security.
