Enjoy the beauty of natural light with this full lite door from Mastercraft®. The low-e glass is a proven energy saver that reduces water, heating, and air conditioning costs by 25-35 percent (US Green Building Council). It reduces solar transmission in the summer and heat loss to the outside in the winter, allowing solar energy to come inside and keep you and your loved ones warm. This door has a left inswing, which means the knob is on the left side of the door when you're pulling it toward you.
