Argon vs Krypton Gas-Filled Windows

Modern high-performance windows are filled with inert gases instead of air to improve insulation. Argon, the most common choice, is inexpensive and provides significant insulation improvement over air-filled windows. Krypton gas, denser and more effective at blocking heat transfer, offers superior insulation but costs significantly more. For most Capital Region homeowners, argon-filled windows provide excellent performance at a reasonable cost.

Krypton excels in applications where space is limited or maximum insulation is critical. Thin triple-pane windows or windows in extremely cold climates benefit from krypton's superior performance. However, for typical double-pane or triple-pane installations in Albany, argon delivers outstanding efficiency at 30-40% lower cost. The difference in annual energy savings between argon and krypton windows is often less than $100 in most Capital Region homes.

Consider your specific priorities when choosing between argon and krypton. If budget is constrained, argon-filled windows represent excellent value. If you have severe cold exposure or aesthetic constraints requiring thinner windows, krypton may justify the extra cost. Discuss your options with your Capital Region contractor, who can recommend the best choice based on your home's characteristics and budget.
