Energy Savings
The Winguard Preferred SGD770 Impact Resistant Sliding Glass Doors are designed to provide superior energy savings with their insulated glass and weather stripping features. The insulated glass helps to reduce heat transfer through the door, keeping the interior cool in summer and warm in winter. The weather stripping helps to seal any gaps between the door and frame, preventing air infiltration and increasing energy efficiency. These energy-saving features not only help to reduce energy costs but also provide a comfortable living environment all year round.
