A garden window projects out from the wall of the house with four window units, adding a mini greenhouse to your home. The two ventilating side units are trapezoidal casement units that open outwards with a crank. The center unit and the roof are picture windows. The insulated glazed roof is designed to be weather tight and leak proof. The garden window gets its name from its resemblance to a miniature greenhouse, which makes it perfect for displaying plants. The result is a beautiful space for greenery that will give you many years of trouble-free service.
