Daryn and the products are simply the best! So glad we went with Eze Breeze. Daryn had the patience of a saint as my design changed several times. End result is a professional looking enclosure with easy operating window panels that are amazingly wind and weather tight. Easy to install if you’re accurate, square and plumb with your openings because their panels are dead on. Suggest you opt for 1/4″ under on long spans as sag and waves are likely and caulking the gap is recommended for professional appearance.
