You may have a high standard air conditioner in your room to keep the room super cool. But you can never keep the energy bounded within the room completely. Recent studies reveal that around 11 percent of air leakage in a house happens through the doors. Even the doors which are well sealed waste a sufficient amount of energy and obviously not tightly insulated as the walls. Therefore the home owners should be careful enough to choose the right door for the house. Energy efficient doors should be the obvious choice for better environment inside the house and also for the lower expenses.
