INSULATING GLASS OPTIONS

Dual Pane

Triple Pane

Dual Pane

Our standard glazing is dual pane: two panes of glass with Low E coatings and insulated with argon gas. Compared to a single glass pane, dual pane glass cuts energy costs significantly because of low emissivity coating and the gas filled insulating space between the glass layers.

Triple Pane

Triple pane glazing provides three panes of glass with Low E coatings. Two glass spaces are insulated with argon gas between the panes.**


Triple Pane: Is it Right for You?
Triple pane (three panes of glass) doesn’t necessarily mean a window is more energy efficient. Glass coatings, the type of gas used in the spaces between the glass, the design of the window, the materials used, and how well it is installed all play a role in achieving the overall energy efficiency. Consider the energy efficiency of the entire window not just the number of panes of glass it has.

A poorly designed or installed window, or a window made with inferior materials like vinyl, may not be energy efficient regardless of the number of panes of glass. Materials shrink and expand with cold/heat cycles and seals can begin to fail. Once seals fail, the energy efficiency the windows claimed when new becomes greatly reduced.

GLASS COATINGS

Low E coatings on the glass surface help manage the amount of light and heat either conducted through a window or reflected away from it, reducing a home’s dependence on energy-consuming climate control systems. The national ENERY STAR® program recognizes products that meet strict energy-efficiency guidelines to suit climates in different areas of the country. Marvin Family of Brands offers products to meet climate and code requirements for various markets across the country.

Low E1
Suitable when maximum solar heat gain is desired balanced with the radiant heat properties of a single Low E coating. Generally used in Northern climates where heating is prioritized over cooling. Maximum benefits are achieved when used on elevations with direct sun exposure.

Low E2
The most common Low E coating since it works well across most geographic regions and climates. Low E2 with two metallic coatings balances less solar heat gain along with improved radiant heat transfer properties over Low E1.

Low E3
Used in applications where solar heat gain may be a concern with multiple metallic layers offering radiant heating properties similar to Low E2. Most commonly used in Southern, sunny climates where cooling is prioritized over heating.

Low ERS
A higher performing Low E glass with significantly improved U Factors. This coating resides on the interior surface of the glass and can be touched. It is used in conjunction with Low E2 or Low E3. This coating is effective at reflecting radiant heat back into the room. This means a slightly cooler interior glass surface since the heat is not absorbed by the glass. The cooler surface may see a bit more condensation in cold climates versus traditional Low E glass make-ups. Also, abrasive products must be avoided when cleaning the glass.


DECORATIVE GLASS OPTIONS

A variety of decorative glass options are available to meet the unique needs of each project.

Laminated glazing is also available in clear, bronze, gray, or green with tinted interlayers.

Not all decorative glass is compatible with all products. Check with your dealer for a recommendation on which glass is right for your project. Images may not be an accurate representation.
