Low-E Options with Argon
Our Low-E vinyl windows with Argon gas come in two options: Climate control optimized for either westward or eastward facing windows. Low-E works like microscopic shutters, minimizing summer heat gains, reducing winter heat loss, and reducing the UV damage to household items. Argon gas is harmless and fills the sealed space between the window panes. It further enhances the window’s climate control efficiency by slowing heat transfer through the air between the panes of glass.
