Marvin continually strives to improve the energy efficiency of its windows and doors. Our new window and door offerings include new glass options, new coating options and design refinements that make our products more energy efficient than ever.
Our guiding principle: Windows and doors should be beautiful, functional, durable and energy efficient.
THE ENERGY EFFICIENCY STORY
Windows and doors are key to your home’s comfort and energy efficiency. Outdated or failing windows are responsible for a large percentage of the wasted energy in homes and other buildings.
In the winter, windows can leak heat or block too many of the sun's warming rays -- meaning you burn more fuel and pay higher utility bills. In summer, poorly performing windows let cool air escape and fail to reflect outdoor heat.
Today’s windows and doors are far more energy-efficient than those of even 10 years ago. Modern, energy-efficient windows and doors can save you 15 to 25 percent on your monthly heating and cooling bills, according to the U.S. Department of Energy.
Where single sheets of clear glass once ruled the day, there are now windows with multiple glass layers. Special coatings on the glass reflect sunlight and ultraviolet rays without dimming the view. Gases injected between panes create extra insulation. Advanced framing materials and innovative design provide further efficiency gains.
Marvin operates at the leading edge of window and door technology. With Marvin, you can have it all -- products that look great and function flawlessly.
MARVIN ENERGY-EFFICIENCY OPTIONS
Marvin allows you to craft a customized solution for your project's unique needs. You can choose from thousands of dual-pane and triple-pane (Tripane) products -- and couple them with the glazing and gas options that help you achieve optimal energy efficiency.
ENERGY STAR
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. So no matter where you live, you can find energy-efficient Marvin windows and doors to suit your needs.
Dual-Pane and Tripane
Marvin offers thousands of window and door options with two or three panes of glass. Dual-pane products with appropriate glazing options are versatile, beautiful and energy efficient.
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 (LoE or Low-E) glazing. Coating a glass surface and gaps between each pane with LoE 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.
LoĒ-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.
LoĒ2-272®: 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.
LoĒ3-366®: 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 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.
Further 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 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. 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.
