Argon Filled Windows R Value

The most common gas between panes is argon.

Argon filled windows r value.

That s a 31 decrease in heat loss. Because argon is more dense than air it does a better job of insulating your home than a regular double pane window. Argon is a safe odorless colorless naturally occurring gas which is denser than air 40 denser than air. 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.

Argon is an inert gas found in our atmosphere. Argon for instance typically increases the insulating r value of a window by only half a point. Energy efficient windows use two or three panes of glass to slow conduction and maintain comfort. Insulated glass windows also called double pane glass typically have an r value of around 2 0 to.

Regardless of the season low e argon gas windows ensure the climate is stable in your home. A virtually invisible low e coating is applied to the glass to help reflect heat and keep your home comfortable. 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. Low e or low emissivity coating is a unique microscopic glaze that helps minimize the amount of ultraviolet infrared and visible light from penetrating the glass keeping you cooler in the summer and warmer in the winter.

Choose to add optional argon gas between the panes to act like an insulating blanket and reduce heat transfer. An insulated argon filled double glazing unit 24mm can have a u value as low as 1 1. U value r value solar heat gain visible light transmittance. Updated october 02 2018.

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. Triple pane one low e coating argon. Dual pane clear glass no coatings. When your windows are filled with argon there is a slightly higher efficiency rating of the window.

Triple pane clear glass no coatings. Dual pane one low e coating argon.
