A garden window projects out from the wall of the house. It has four window units. 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 to be weather tight and leak proof. It’s called a garden window because it provides an ideal environment for growing plants indoors. It’s the next best thing to adding a small conservatory to your house, and much easier on your budget. The result is a beautiful new green space that will give you many years of trouble-free service.
