How Energy-Efficient Windows Lower Your Tennessee Energy Bills

Power bills add up fast in East Tennessee. Long, humid summers and cold, damp winters keep your heating and cooling system working overtime. If your windows are old or leaky, you are paying to heat and cool air that escapes outside.

Here is how modern, energy-efficient windows lower your bills and make your home more comfortable.

Where homes lose energy through windows

Windows lose energy three ways. Heat moves through the frame and glass. Air leaks around worn seals. And heat from the sun passes right through the glass. Old single-pane and metal-frame windows are the worst at all three.

What makes a window energy-efficient

Two or three panes of glass

Several panes with insulating gas sealed between them slow heat far better than one pane. This is the single biggest upgrade over an old window.

Low-E coatings

A low-emissivity, or Low-E, coating reflects heat. In summer it keeps heat out. In winter it keeps your heat in. That matters during our long Tennessee summers.

Tight frames and seals

Modern vinyl frames resist heat and hold their seal much longer than worn wood or metal. A good frame plus a proper install stops the drafts that run up bills.

What this means for your bill

When your windows seal tight, your HVAC does not fight leaks all day. It runs less and lasts longer. Most homeowners feel the difference in comfort right away and see it on the power bill over the next few seasons.

More than savings

Energy-efficient windows also cut outside noise, reduce cold spots, and block the UV rays that fade floors and furniture. Your home feels better year-round.
