Argon Filled Windows R Value

The most common gas between panes is argon.

Argon filled windows r value.

Argon is a safe odorless colorless naturally occurring gas which is denser than air 40 denser than air. Energy efficient windows use two or three panes of glass to slow conduction and maintain comfort. U value r value solar heat gain visible light transmittance. Energy efficient windows also have a positive impact on the environment by reducing your home s overall carbon footprint and lengthening the lifespan of its energy systems.

Regardless of the season low e argon gas windows ensure the climate is stable in your home. Dual pane one low e coating argon. Argon is an inert gas found in our atmosphere.

Insulated glass windows also called double pane glass typically have an r value of around 2 0 to. A virtually invisible low e coating is applied to the glass to help reflect heat and keep your home comfortable.

That s a 31 decrease in heat loss. An insulated argon filled double glazing unit 24mm can have a u value as low as 1 1. Thermal windows also called insulated glass units or igu are either double pane or triple pane meaning each section of window has two or three layers of glass with a sealed space in between.

Andersen offers products made with our exclusive fibrex composite material that is composed of 40 reclaimed wood fiber by weight. When your windows are filled with argon there is a slightly higher efficiency rating of the window. Updated october 02 2018.

Argon gas is used to increase the energy efficiency and general performance of thermal windows. When used in conjunction with low e glass argon provides better insulation because heat and cold do not pass through argon gas as easily as through air providing better performance.
