GLASS INSULATING OPTIONS

Dual Pane

Our standard glazing for dual-pane windows consists of two panes of glass with Low E coatings insulated with argon gas. Because of the low emissivity coating and the gas-filled insulating space between the glass layers, dual pane glass significantly reduces energy costs compared to a single glass pane.

Triple Pane

Triple pane glazing consists of up to three panes of glass with Low-E coatings on the surface. Argon gas fills the spaces between the panes for added insulation.**

Is Triple Pane Best Option for You?

Triple pane does not always imply a more energy-efficient window. Design, materials, type of gas that fills the space between the glass, and the installation quality are contributing factors to the overall energy efficiency of a window. Consider the overall energy efficiency of the window, not just the number of glass panes.

A poorly designed window made of inferior materials such as vinyl is not energy efficient, regardless of the number of panes of glass. Cold/heat cycles cause window materials to shrink and expand and seals to fail. When seals fail, it compromises the energy efficiency of the windows regardless of the number of panes. It is best to request assistance from a window professional in determining the most suitable package for your home and climate.

GLASS COATINGS

Low-E coatings are microscopically thin, virtually invisible coatings on the glass surface that help manage the amount of light and heat transmitted through or reflected away from a window-pane, reducing a home’s reliance on heat and air conditioning. The national ENERGY STAR® programme recognizes products that meet strict energy-efficiency guidelines tailored to different climates across the country, and Marvin has products to meet climate and code requirements in every region.

Low E1

To achieve maximum solar heat gain (or heat transfer from the sun into your house) and radiant heating properties, it is best to use a low E1 (keeping the heat on the side of the glass where it originated). Application of this type of coating is common in northern climates, where heating takes precedence over cooling. When windows with this type of coating come in contact with direct sunlight, you will reap the most benefits.

Low E2

Because it works well in most geographic regions and climates, it is the most commonly used Low E coating. Low E2 with two metallic coatings balance less solar gain with better radiant heating properties.

Low E3

Low E3 coating, which is used in applications where solar heat gain is a concern, employs multiple metallic layers to achieve radiant properties similar to Low E2. This type of coating is most common in hot, southern climates where cooling takes precedence over heating.

Low ERS

A better performing Low E glass with significantly higher U Factors (ability to keep heat inside of your home). This coating is applied to the interior surface of the glass and is touchable. When used in conjunction with Low E2 or Low E3, it aids in reflecting radiant heat back into the room. Because the glass does not absorb the heat, the interior glass surface is slightly cooler. In cold climates, the cooler surface may experience more condensation than traditional Low E glass make-ups. When cleaning the glass, avoid using abrasive products.

Decorative Glass

A wide range of decorative glass options is available to meet the specific requirements of each project.

Laminated glass is also available with tinted interlayers in clear, bronze, grey, or green.

Options for Specialty Glass

Our specialty options are glass for unique project needs such as sound reduction (STC/OITC), high altitudes, Sea Turtle Conservation Codes*, and California fire zones. We also provide laminated glass on certain products that are specifically designed for hurricane zones.
