  • Insulated Windows 101 — Double Glazing, Triple Glazing

    Insulated Windows & Glass — Basic OverviewThermal Performance, R-Values, & SoundproofingPotential Problems — Cracking, Condensation, & LifespanInsulated windows and glass are essentially an insulation solution whereby multiple layers (panes) of glass are used in place of a single layer/pane — with the spaces between these panes generally being turned into a vacuum or filled with a gas with lower thermal conductivity and heat capacity than “air” (such as argon, or sometimes krypton). Double glazing refers to the use of two panes of glass with an evacuated space between or a high-performance fill-gas, and triple glazing refers to three panes of glass with two evacuated spaces or gas-filled spaces. Generally speaking, the glass panes used in such systems vary between 1/8″ to 3/8″ in thickness (3-10 mm) — with both/all of the panes being of the same thickness in the same window, though there is some variance when sound-insulation is a desired quality as well. The two or three glass panes in question (in double- or triple-glazed windows), are turned into a cohesive unit through the use of what’s termed a “spacer” — which is usu...
