Argon Filled Windows R Value

Argon is a safe odorless colorless naturally occurring gas which is denser than air 40 denser than air.

Argon filled windows r value.

That s a 31 decrease in heat loss. You might also like. 4 building construction ff 1. Argon gas windows have an increased r value which is the measure of resistance to heat.

Choose to add optional argon gas between the panes to act like an insulating blanket and reduce heat transfer. Being cheaper argon is usually used to fill the wider 1 2 inch spaces between panes in double pane windows while krypton. Argon for instance typically increases the insulating r value of a window by only half a point. Insulated glass windows also called double pane glass typically have an r value of around 2 0.

An insulated argon filled double glazing unit 24mm can have a u value as low as 1 1. That means argon gas windows are more resistant to heat causing them to lose less heat during the winter. All c o g u and r values are based on ashrea winter conditions. Windows with krypton fill tend to have lower u values better insulating quality and are more expensive than argon filled 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. The total heat transfer out of a window btu hr sq ft f or w sq m c. Framing cladding frame type and other items will affect the overall thermal values of a complete window. Thermally efficient argon filled window units have low r values.

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. For the average detached you ll lose about 17 5 of heat through c rated windows and just 12 25 with an argon filled a rated window. A virtually invisible low e coating is applied to the glass to help reflect heat and keep your home comfortable. The inert gases also don t move easily so gas filled windows have fewer internal air currents that can cause hot and cold spots in conventional windows.

Chapter 4 building construction. A gas filled window has an r value about. Storm water can be collected from a roof and used for garden irrigation or toile flushing. Energy efficient windows use two or three panes of glass to slow conduction and maintain comfort.

The amount of heat retained by the window. Argon typically represents a better value overall especially with double pane windows.
