Energy Efficient Solutions

Marvin allows you to craft a customized energy solution for your project's unique needs. You can choose from thousands of options to help you achieve optimal energy efficiency.

Dual-Glaze and Triple Glaze

Marvin offers thousands of window and door options with two or three panes of glass and/or suspended films.

Insulating Glass Coatings

Extremely thin coatings of special metallic material applied to glass panes used in windows and doors to boosts their energy efficiency. The industry standard for energy-efficient glass coatings has become Low-Emissivity (Low E) glazing. Coating a glass surface between each pane with Low E material can block a significant amount of heat transfer, reducing your home’s need for energy-consuming climate control systems.

Low E coatings are transparent to visible light, and different types of coatings have been designed to allow for high solar gain, moderate solar gain or low solar gain.

Climate Options

Single Layer Metallic Low E Coatings, such as Low E1, allow the sun’s warming rays to pass through, and are ideal in applications where solar heat gain is desired, such as northern climates. Low E1 Features a single metallic coating and an insulator that blocks heat loss to the outside while reflecting heat back into a room. Provides a low U-factor and a high solar heat gain.

A Double Layer Metallic Coating, such as Low E2, is suitable for all climates, except the southern ENERGY STAR zone. It features a double metallic coating on the inside glass surface to reflect heat into the room in winter and reject the sun's warmth in summer, reducing damaging UV rays. This coating option provides better protection against radiant heat transfer than single layer metallic Low E coatings.

Triple Layer Metallic Coatings such as Low E3 are often specified in the southern ENERGY STAR zone where cooling costs are high and intense exposure to the sun is an issue. It features three metallic layers of silver. This coating offers the lowest U factor and lowest solar heat gain.

Insulating Gases

Insulating gases fill the spaces between the glazing layers. These inert gases are pumped into the spaces between panes of glass to slow the transfer of heat, increasing the insulating power of a window or door.

Argon - Our standard windows and doors come with argon gas between the panes to boost energy efficiency.

Krypton - Customers seeking to maximize energy savings can consider our blend of krypton, argon and air. This option increases the insulating capabilities by lowering the U-Factor with narrow airspaces.

Additional Performance Options

Marvin offers these enhancements to further increase the energy efficiency of our windows:

Energy Panel

Often confused with storm windows, an energy panel is a glazing option consisting of a removable exterior glass panel finished on the edges with a surround. Energy panels cover the exposed glass surface of each sash, and offer added energy efficiency for wood windows with single glazing.

Storm and Screen Combos

A combination unit is composed of two movable glass panels and one movable screen panel. The individual panels can be configured multiple ways, and can be easily removed from the interior for cleaning. Customized commercial screens are also available.

Low Air Infiltration

All Marvin window and door products meet the WDMA requirements for maximum air infiltration.

XL Edge Spacer

Marvin offers the warm-edge XL Edge spacer from Cardinal IG – the most durable spacer system on the market. The spacer helps prevent energy loss around the perimeter of the window glass.

Fully Integrated Shades

When used correctly, shades can help lower energy use and provide significant thermal benefits.
