Energy Efficient Windows: How to Read the Label and Pick the Right Glass
The NFRC label and your climate zone tell you more about a window's efficiency than any brochure. Here is how to read both and choose glass that fits your home.
Window Repair vs Replacement: Fogged Glass, Rot and Drafts Explained
Many window problems can be fixed for a fraction of the price of new units. The key is knowing which problems are cosmetic and which signal a failing window.
Replacing windows is one of the larger home improvement projects most owners take on, and the quotes can vary widely for what looks like the same job. The difference usually comes down to frame material, glass package, window style and whether the installer replaces the full frame or fits an insert into the old one.
Start with our breakdown of window replacement cost to see how those choices move the price. If energy bills are the main concern, our guide to energy efficient windows explains the NFRC label and ENERGY STAR climate zones. And if you are dealing with fogged glass, drafts or soft wood, read window repair vs replacement before you commit to new units.
How to use these guides
Begin by diagnosing the problem. A single failed seal or a stuck sash is often a repair. Widespread rot or many failing windows usually points to replacement. Next, set a budget using realistic per-window ranges and a contingency for hidden damage. Finally, collect several itemized bids and vet each installer using our checklist on how to hire a contractor.
Note that the federal Energy Efficient Home Improvement Credit (Section 25C) ended for property placed in service after December 31, 2025. Check state, local and utility programs for any remaining rebates.
Key terms to know
- U-factor: how easily heat passes through the whole window; lower is better.
- SHGC: how much solar heat gets through; the right value depends on your climate.
- Insert vs full-frame: an insert fits inside the existing frame, while full-frame replacement removes it down to the rough opening.
- IGU: the insulated glass unit, the sealed panes that fog when the seal fails.
- Low-E: a thin coating that reflects heat to improve efficiency.
Storm-damaged windows may be covered by insurance, while worn-out ones generally are not; our guide to what homeowners insurance covers explains the difference.
