Pros: More affordable than full replacement; preserves the existing frame.Cons: Does not restore the lost argon gas, suggesting the window's original R-value (insulative residential or commercial property) is just partially recuperated.2. IGU Replacement (Glass-Only Replacement)If the frame and sash are in great condition, a glass professional can order a replacement Insulated Glass Unit (IGU) and fit it straight into the existing frame. This is the most typical approach for professional double-pane window repair.Pros: Restores complete energy performance and clearness; more affordable than changing the whole window.Cons: Requires accurate measurements and professional installation.3.
