Window Replacement in Chattanooga, TN

ENERGY STAR Certification and Your Chattanooga Utility Bill

The windows we build for the Tennessee Valley carry ENERGY STAR (opens in a new tab) certification for South Central and Southern climate zones (opens in a new tab), and Chattanooga sits inside that coverage. ENERGY STAR states the payoff plainly: “Replacing old windows with ENERGY STAR certified windows lowers household energy bills by an average of up to 13 percent nationwide when replacing single-pane windows. Lower energy consumption also reduces greenhouse gas emissions from power plants and homes.”

Chattanooga’s Temperature Swing Is the First Thing to Design For

A window in this valley has to do two opposite jobs six months apart. Figures from the National Oceanic and Atmospheric Administration (opens in a new tab) put the Chattanooga Metropolitan Area (opens in a new tab) at 33°F to 55°F through the winter and 71°F to 91°F through the summer, and the record books add another 10°F of heat above that normal range and 30°F of cold below it. Solid vinyl would hand all of that a straight path indoors, so the frames and sashes on Windows USA windows are divided into sealed chambers instead — the still air caught in each chamber is what interrupts the transfer, and it is also what makes the frame rigid enough to stay square. Where the two sashes meet, an interlocking rail draws them into one continuous line of contact rather than leaving them resting against one another, which is how the seal holds against air and water past what the industry asks of it.

Forty to Seventy Inches of Rain a Year Changes the Sealing Requirement

Rain is the other constant here. Records kept by the National Centers for Environmental Information (opens in a new tab) show the Chattanooga area generally taking in between 40 and 70 inches of precipitation annually, and every inch of it eventually runs down a pane of glass. Water gets turned away at three points on our units. The interlocking sashes hold the joint where the two halves meet. Intercept® Ultra spacers keep the sealed glass unit airtight at its perimeter. And weep holes, cut into the bottom of the frame, give whatever water does find its way in a route back out to the yard instead of into the wall.

How Hard the Sun Works on a Chattanooga Metropolitan Area (opens in a new tab) House

Tennessee takes more ultraviolet light than most of the continental United States, and the Chattanooga area is no exception. CDC (opens in a new tab) tracking of Average Daily Dose of Ultraviolet (UV) light (opens in a new tab) places the state toward the higher end of their scale (opens in a new tab).

That comes with two different kinds of damage. For the people inside, ordinary window glass is not the barrier most homeowners assume: the International Ultraviolet Association (opens in a new tab) is blunt about it — UVA goes straight through — and the Skin Cancer Foundation (opens in a new tab) flags UVA as a primary agent in premature skin aging. Those same rays are quietly bleaching whatever they land on, since UV light from sunlight can damage furniture, fabrics, flooring, and artwork & photos (opens in a new tab), among other items.

The window itself is a target too. Ultraviolet (UV) wavelengths can penetrate solid surfaces, significantly damaging most materials that receive overabundant exposure (opens in a new tab), and unprotected vinyl shows it — researchers document undesirable mechanical, physical and chemical consequences of the resulting degradation from solar radiation (opens in a new tab) that surface as cracking, chalking (opens in a new tab), color shift, and a frame that has lost its physical properties.

Which is why a UV inhibitor goes into the vinyl on every one of our windows and patio doors, so the frame will not fade, flake, or peel even where the exposure is unrelenting. The glass (opens in a new tab) is engineered against the same problem, with a triple-layer coating that does three things at once:

• Turns solar gain back outside and reflects heat while daylight keeps streaming in — it beats the tinted glass warm-climate builders often reach for, because it rejects the sun’s heat without dulling the view.
• Stops 95% of the ultraviolet that does the damage, so rugs, upholstery, curtains, and wall coverings hold their color year after year.
• Insulates well enough that the indoor face of the glass stays warm on a cold night, and warm glass is what lets indoor humidity be held where it belongs — a real comfort difference through a valley winter, and a healthier room to live in.

Before you settle on a glass package, it is worth tracing the direction the sun (opens in a new tab) travels every day (opens in a new tab) across your own lot and noting which walls take the brunt of it. A west-facing bank of windows in Chattanooga carries a very different load, hour for hour, than one facing north, and that load decides how much solar control belongs in the glass as well as how much heat the frame itself has to shrug off without distorting.

The U.S. Department of Energy (opens in a new tab) makes the same point: orientation can change the technical specification a window ought to meet.

Storm Season Is a Real Consideration in Southeast Tennessee

Chattanooga sees more tornadoes than most of the country does. The National Oceanic and Atmospheric Administration’s National Weather Service Storm Prediction Center (SPC) (opens in a new tab) shows counties across Tennessee with a relatively high count of Tornadoes in the past thirty-five years (opens in a new tab). Be clear about what a window can and cannot do here: nothing on the residential market comes through a direct hit, and we will not claim otherwise. What better frames and sealed double-pane glass do change is the ordinary severe weather in between — the wind-driven rain, and the pressure and temperature extremes that arrive far more often than a tornado does.

Particulates and the Case for an Airtight Seal

Statewide the picture is a good one. The U.S. Environmental Protection Agency (EPA) Air Quality System (AQS) (opens in a new tab) finds air quality across most of Tennessee is very good (opens in a new tab), with the qualification that Chattanooga itself records pockets of mildly raised particulate matter. A window cannot filter anything, but a leaky one keeps trading air with the outdoors on its own terms, all day. The seal is what gives the choice back: Intercept® Ultra closes the glass unit, the interlocking sashes close the frame, and what comes into the house comes in when you open a window.

Traffic, Rail, and Aircraft Noise Around Chattanooga

Federal transportation mapping finds that Tennessee generally does not have high levels of noise exposure (opens in a new tab) from aircraft, highways, and rail lines — with the larger cities as the exception, and Chattanooga among them, registering high. A statewide average says little about a particular address, though: how close you sit to the airport, the interstate, or an active rail line moves your own exposure well above or below the map. The Environmental Protection Agency (opens in a new tab) is direct about the stakes: noise pollution “adversely affects the lives of millions of people”, and the agency cites “direct links between noise and health”. Two panes with argon between them absorb a good share of that sound before it reaches the room, which is the second reason valley homeowners on a busy corridor end up glad they replaced single-pane glass.

Put the pieces together and here is what a Chattanooga homeowner actually gets out of a double-pane vinyl window:

• Lower energy use: the argon fill slows heat moving through the glass in both directions, so the air conditioner runs less in July and the furnace runs less in January.
• A frame that stays put: it is vinyl, so there is nothing to rot, rust, or repaint, and nothing that warps out of square.
• A quieter house: the second pane and the gas behind it take the edge off traffic and neighborhood noise.
• Better security: the locking hardware is designed into the sash rather than added onto it.

Built to Fit Chattanooga-Area Homes, Opening by Opening

No two houses on the same street have the same openings, which is why every window is manufactured to measured dimensions rather than pulled from a rack of stock sizes. That holds whether you are in Chattanooga (opens in a new tab) proper or out in Ooltewah (opens in a new tab), Soddy-Daisy (opens in a new tab), Rossville (opens in a new tab), La Fayette (opens in a new tab), Chickamauga (opens in a new tab), Fort Oglethorpe (opens in a new tab), or anywhere else across East Tennessee (opens in a new tab) — and professional installation crews‡ work in all of it.

Reasons Chattanooga Homeowners Stop Repairing and Start Replacing

A single-pane wood or aluminum window can be caulked and puttied for years before anyone admits it is the problem. Three things usually settle the argument:

• The energy math: one pane of glass insulates next to nothing, and the bill reflects that every month of the year.
• Resale: new windows read immediately from the street and show up again in an appraisal.
• Day-to-day comfort: the drafts stop, and the room by the window stops being the cold room.

How We Stand Behind the Work
