Finding the Best Windows for Your Home
Finding the best windows for your home depends on your window material preference, energy efficiency, window style, and budget.
Window Frame Material
Finding the best windows for your home starts with the material you choose. Common window materials include wood, vinyl, aluminum, or fiberglass. Each window material offers different performance and style features. At Marvin Replacement, we use Ultrex® fiberglass Ultrex® fiberglass A pultruded composite material made of resin and glass fibers with an integrated proprietary finish.
Fiberglass Windows
Marvin Replacement uses Ultrex fiberglass for its windows to provide a window 8x stronger than vinyl with virtually zero maintenance.
Ultrex fiberglass also helps keep homes cooler in the summer and warmer in the winter because it’s 5,000x less conductive than aluminum.
Our windows have five different interior color options, including EverWood®, our stainable finish that mimics the look of wood. We offer seven exterior window colors: Stone White, Sierra, Ebony, Pebble Gray, Cashmere, Bronze, and Bahama.
Our finishes last long—48,000 hours of sun can’t fade our finishes.

Wood Windows
Wood is a classic favorite for windows, but wood windows can require care and maintenance.
Wood windows can get painted or stained in any color to suit a home and are energy efficient.
Vinyl Windows
Homeowners like vinyl windows because of their durability and versatility.
Vinyl works well in most climates but if exposed to direct sunlight and extreme temperatures, it can expand. In extreme cold temperatures it can contract and become brittle.
Vinyl windows offer an affordable window option and can come in colors to match your home.
Painting vinyl, however, usually takes a special kind of paint because paint doesn’t adhere well to vinyl due to its expansion and contraction.
Aluminum Windows
Homeowners value aluminum windows because of their strength and durability.
Some manufacturers combine aluminum with wood for aluminum-clad wood windows, which can help improve energy efficiency.
Since aluminum is a metal, it has high conductivity, meaning hot and cold temperatures pass through it easier than other materials.
Window Glazing Options
Window glazing plays an important role in helping your home’s energy efficiency. Different glazes work better in specific climates. Our glazing options include: Low E1, Low E2, Low E3, and Low E3/ERS. E stands for emissivity and the number represents the number of metallic coatings. Learn more about glazing and energy efficiency.
Energy Efficiency
Windows can help a home’s energy efficiency through their U-factor, U-factor U-Factor is a measure of how well a window retains heat in a home. A higher U-Factor allows more heat to escape a home and a lower number will allow less heat to transfer out of a home. Solar Heat Gain Coefficient Solar Heat Gain Coefficient measures how much heat from the sun enters a home. A lower SHGC number allows less heat. Visible Transmittance Visible transmittance is the measure of visible light that will pass through a window. A higher VT number maximizes daylight.
Window Styles
Marvin Replacement offers a variety of windows and each style can work better in certain spaces.

Window Options
Marvin Replacement has window options like grilles between the glass Grilles Between the Glass Dividers placed between the panes of insulated glass to simulated authentic divided lites. GBGs allow for easier window cleaning with no bars on the exterior or interior surface of the glass. Simulated Divided Lites Simulated divided lites get permanently adhered to the outside surface of glass to give the appearance of divided lites. Simulated divided lites have a spacer bar between the panes of glass.
Grilles Between the Glass
Grilles between the glass are divided lites that go in between window panes.
Simulated Lites
Simulated lites appear on the exterior of window panes and form lines for an added design element.
