Window Replacement in Baton Rouge, LA

ENERGY STAR Certification for a Long Louisiana Cooling Season

In a place where the air conditioner runs most of the year, the efficiency rating on a window is not a formality. Windows USA units are ENERGY STAR (opens in a new tab) certified for South Central and Southern climate zones (opens in a new tab), the zones covering Baton Rouge. According to ENERGY STAR, “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.”

What a 98°F Summer Does to a Baton Rouge Power Bill

Averages published by the National Oceanic and Atmospheric Administration (opens in a new tab) for the Baton Rouge metropolitan area (opens in a new tab) run 42°F to 65°F through winter and 73°F to 98°F through summer, and the records go 10°F past the top of that summer range and 20°F below the bottom of the winter one. Read it as a cooling load nine months long with a genuine cold snap dropped into the middle. Windows are where that load enters and leaves a house, so we build against both directions: the frames and sashes on every Windows USA window are extruded with multiple internal chambers, so heat has to work its way across a run of dead-air cavities, and the sashes interlock into one unbroken seal that keeps conditioned air in and humid outside air where it belongs.

Forty to Seventy-Five Inches of Rain, and Where It Ends Up

Records from the National Centers for Environmental Information (opens in a new tab) show the Baton Rouge area receiving 40 to 75 inches of precipitation in a normal year, delivered in the sort of afternoon storms that drive water sideways against a wall. What separates a window that handles that from one that does not is drainage as much as sealing. Ours is sealed at the glass by Intercept® Ultra spacers and at the sashes by an interlocking design that resists air and water infiltration beyond industry standards — and then drained by weep holes, small openings positioned in the frame so anything that does get past the first two lines runs back outside instead of soaking into the sill.

The Louisiana Sun, Your Rooms, and Your Baton Rouge (opens in a new tab) Window Frames

According to the CDC (opens in a new tab), the Baton Rouge area and Louisiana generally record an Average Daily Dose of Ultraviolet (UV) light (opens in a new tab) at the higher end of their scale (opens in a new tab) compared with the rest of the continental United States.

Ask what that costs you and the answer comes in three parts. Your furnishings go first: sunlight through glass fades furniture, fabrics, flooring, and artwork & photos (opens in a new tab) without ever announcing itself. Your skin is next, since the International Ultraviolet Association (opens in a new tab) notes ordinary window glass lets UVA into the room, and the Skin Cancer Foundation (opens in a new tab) ties UVA exposure to premature skin aging. And the window pays too: ultraviolet wavelengths penetrate solid surfaces and damage most materials that receive too much exposure (opens in a new tab), giving vinyl mechanical, physical and chemical consequences of solar degradation (opens in a new tab) that appear as cracking, chalking (opens in a new tab), discoloration, and lost strength.

Our windows and patio doors are made with a UV inhibitor in the vinyl itself, which is what stops the surface chalking, peeling, or bleaching out in this climate. The glass (opens in a new tab) takes the other half: its triple-layer coating sends solar heat back outside before it becomes a cooling load, with the daylight left intact, and it does that better than the tinted glass so often used in warm climates, because it is engineered to reject heat rather than to darken a room. Ninety-five percent of the sun's damaging ultraviolet stops at the coating, which is what keeps upholstery and flooring from bleaching out over the years. It also insulates strongly enough to keep the interior glass surface warm during a cold snap, and warm glass makes it far easier to hold indoor relative humidity where it should be — no small thing in a climate this damp.

Before ordering, it is worth studying where the sun tracks (opens in a new tab) across your property during the day (opens in a new tab) and matching it against the direction each opening faces. West-facing glass in Baton Rouge absorbs the day's worst heat at the hour the house is already warmest.

That is not just our opinion: the U.S. Department of Energy (opens in a new tab) recommends different U-factor and solar heat gain targets for north, south, east and west elevations, which means which way an opening looks can move the technical specification it ought to meet.

Tornadoes and Severe Weather Around Baton Rouge

Tornadoes reach the Baton Rouge area at a moderately high rate, and the statewide picture is heavier still — the National Oceanic and Atmospheric Administration's National Weather Service Storm Prediction Center (SPC) (opens in a new tab) puts tornado counts in parts of Louisiana among the highest in the country over the last thirty-five years (opens in a new tab). We would rather be straight with you about the limits: a tornado that reaches your house is not something a window is rated to stop, and no honest installer will claim otherwise. The value shows up on the many more days of hard wind, sideways rain, and abrupt temperature change that come with the same weather pattern.

Baton Rouge Air Quality and the Argument for Sealed Openings

Measurements in the U.S. Environmental Protection Agency (EPA) Air Quality System (AQS) (opens in a new tab) show air quality across most of Louisiana to be very good (opens in a new tab), with somewhat raised particulate readings recorded in Baton Rouge specifically. An opening that leaks brings that air in around the clock along with the humidity behind it. Sealing is the whole answer: Intercept® Ultra keeps the glass unit airtight, and the interlocking sash system closes the moving joint that leaks first in an older window.

How Loud Is It Where You Live in Baton Rouge?

By the U.S. Department of Transportation's reckoning of aviation, highway, and rail sources, Louisiana is not among the noisier states (opens in a new tab), with Shreveport the standout exception. Averages of that kind say nothing about a particular street, though — an address near I-10, a rail line, or the airport hears something else entirely. And the consequences reach past irritation: the Environmental Protection Agency (opens in a new tab) states that noise pollution “adversely affects the lives of millions of people”, with “direct links between noise and health”.

Four things change in a Baton Rouge house once the old windows come out:

• The cooling costs less. Argon sealed between the panes slows heat transfer, so the air conditioner is not fighting the windows all summer.
• The frames stop deteriorating. Vinyl does not warp, rot, or corrode in Gulf humidity the way wood and aluminum do, and it never wants paint.
• The house gets quieter. A sealed double-pane assembly cuts the traffic and neighborhood noise that used to come straight through single glazing.
• The openings get safer. Modern locking hardware is a real upgrade on a latch that has been painted over for decades.

Windows Made to Fit Your Baton Rouge Home

Every unit is built to the measurements taken at your house and fitted by Windows USA installers‡, which is why odd sizes and older framing are routine rather than a problem. We cover Baton Rouge (opens in a new tab) together with Denham Springs (opens in a new tab), Gonzales (opens in a new tab), Prairieville (opens in a new tab), Zachary (opens in a new tab), Plaquemine (opens in a new tab), Saint Francisville (opens in a new tab), and Port Allen (opens in a new tab), plus the rest of Greater Baton Rouge (opens in a new tab).

The Case for Retiring Old Single-Pane Windows

Wood and aluminum single-pane windows were never built for a climate that runs this hot and this wet, and they get less efficient every year as the seals and the frames give up. Replacing them puts insulation where there effectively was none, which shows up on the utility bill; it takes away the drafts and the hot spots near the glass that keep certain rooms unused; and it visibly changes the house, which matters whenever you come to sell.
