Thinking about energy efficiency? Think Marvin Windows and Doors



Marvin allows homeowners to craft a customized solution for their project’s unique needs. Choose from thousands of dual-pane and triple-pane (Tripane) products — and couple them with the Low E coating and gas options that help achieve optimal energy efficiency.

ENERGY STAR is a federal program that determines where a variety of products, including windows and doors, meet certain
energy-efficiency standards. Products that achieve specific benchmarks can display the ENERGY STAR label. Marvin offers an extensive roster of products and options that meet ENERGY STAR standards. With windows and doors, the ENERGY STAR standards vary by climate – and Marvin offers ENERGY STAR options in each one.

Dual-Pane and Tripane
Marvin offers thousands of window and door options with two or three panes of glass: versatile, beautiful and energy efficient.

Tripane With Krypton
Our most energy-efficient window ever. Three panes of glass with Krypton gas between the panes for truly superior performance in the most challenging climates.

Insulating Glass Coatings
Extremely thin coatings of special metallic material applied to glass panes used in windows and doors boosts their energy efficiency. The industry standard for energy-efficient glass coatings has become low-emissivity. Coating a glass surface adjacent to gaps between each pane with low-emissivity material can block a significant amount of heat transfer. Low-emissivity 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.

LoE-180™: A great insulator (low U-Factor) that allows the sun’s warming rays to pass through (high SHGC). LoE-180 features a single metallic coating and an insulator that blocks heat loss to the outside while reflecting heat back into a room. This type of coating is ideal for applications where high solar gain is desired, such as northern climates.

LoE2-272®: 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 heat loss than LoE-180. It has good solar gain control. Suitable for all climates except the Southern zone of ENERGY STAR.

LoE3-366®: Features three metallic layers of silver. This coating offers the lowest U factor and lowest solar heat gain. It is often specified in the Southern ENERGY STAR zone where cooling costs are high and intense exposure to the sun is an issue.

Insulating Gases
Inert gases pumped into the spaces between panes of glass 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 power of our Tripane products with narrow airspaces.


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 by 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. A combination that placed in front of a dual pane product has a U-factor comparable to that of a Tripane unit and it helps protect the primary unit from the elements. 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 or exceed the WDMA requirements for maximum air infiltration.
  • XL Edge™ Spacer: Marvin offers the warm-edge XL Edge™ spacer from Cardinal – the most durable spacer system on the market. The spacer helps prevent energy loss around the perimeter of the window glass.
