Energy efficient windows are one of the most effective upgrades a Tulsa homeowner can make to reduce utility bills and improve year-round comfort. Oklahoma’s climate is demanding in both directions — long hot summers that drive up cooling costs and cold winters that expose every gap and failed seal. The right windows work with your HVAC system rather than against it, keeping heat out in summer and warmth in during winter. Tulsa Window Pros installs energy efficient windows for homes across the Tulsa metro area.
If your current windows are single pane, have failed seals, or were installed more than fifteen years ago, there’s a good chance they’re costing you money every month. Replacing them with modern high-performance units typically delivers a noticeable reduction in energy bills and a significant improvement in indoor comfort — fewer drafts, more consistent temperatures, and less reliance on heating and cooling to compensate for what the windows are letting in or out.
What Makes a Window Energy Efficient
Energy efficiency in windows comes down to three core elements — the glass specification, the gas fill between the panes, and the frame material. Each one contributes to the overall thermal performance of the unit.
Low-E glass has a microscopically thin metallic coating applied to one of the inner glass surfaces. This coating reflects infrared heat while allowing visible light to pass through — in summer it reflects radiant heat from the sun back outside, and in winter it reflects heat from inside the room back inward rather than allowing it to escape through the glass. The result is a window that performs well in both heating and cooling seasons without significantly reducing natural light.
Argon gas is used to fill the space between the panes in a double or triple pane unit. Argon is denser than air and conducts heat more slowly, reducing the rate at which warmth transfers through the glass. Combined with a low-E coating, an argon-filled unit provides substantially better insulation than a standard air-filled double pane window.
Frame material also plays a role. PVC frames are low-conductivity by nature — they don’t transfer heat the way aluminium frames do — and they require no painting or sealing to maintain their performance over time. All energy efficient windows we install are independently rated by the NFRC, giving you verified U-factor and solar heat gain coefficient figures before any installation begins.
Understanding the Key Performance Ratings
Two numbers matter most when evaluating energy efficient windows for a Tulsa home. The U-factor measures how quickly heat passes through the window — the lower the number, the better the insulation. For Oklahoma winters, a U-factor of 0.30 or below is a strong target. The solar heat gain coefficient (SHGC) measures how much solar radiation passes through the glass as heat — the lower the number, the less heat enters the room. For Tulsa’s south and west-facing windows that take direct afternoon sun through summer, a low SHGC is particularly valuable.
Energy Efficient Window Installation in Tulsa
We install energy efficient windows across the full range of styles — double hung, casement, sliding, and bay and bow configurations. Every unit is precisely measured, correctly fitted, and fully sealed to ensure the performance ratings you’re paying for are actually delivered in practice. A well-specified window that’s poorly installed will never perform to its rated figures.
We serve homeowners across Tulsa, Broken Arrow, Owasso, Bixby, Jenks, Sand Springs, and Sapulpa. Call us on (918) 359-9933 or complete our Free Estimate form for a free no-obligation estimate.
