A great door does more than secure your home and welcome guests. It also plays a vital part in your home’s overall energy efficiency. Here’s how to determine if your current door is wasting energy (and money), and what you should consider when selecting an energy efficient door.
How efficient is your current door?
Many older doors leave much to be desired in terms of energy efficiency. Consider the following factors:
-
Do you have a skeleton keyhole? If so, you have a literal hole in your door, letting outside air in and conditioned air out.
-
Do you have single-pane glass? If so, it’s costing you on your heating and cooling bill. It might be time to upgrade to insulated double-pane glass.
Is your door drafty? If you can see light around the top or sides of your door, you have a poor seal. If you can slide a dollar bill under your door when closed, you’re losing energy there, too.
Components close the door on drafts
Energy efficiency isn’t just about the door itself. Components like compression weatherstrip, heavy-duty door sweeps and rot-resistant sills and jambs all play an important part in forming a tight seal and boosting energy efficiency. Learn more about how these parts are engineered to last as a complete door system.
Certified ENERGY STAR® compliant
Most Therma-Tru Benchmark doors meet the rigorous ENERGY STAR® program qualifications for energy efficiency. ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy, helping protect the environment through energy-efficient products and practices.
