The Material
What Sets the 100 Series Apart
The 100 Series launched in 2008, and Andersen built its ten millionth 100 Series window in 2025. Here is what the line is made of and why it holds up.
Fibrex® Composite
Andersen makes Fibrex from wood fiber and a thermoplastic polymer, with 40 percent reclaimed wood fiber by weight.
Made for Strong Sun
Andersen 100 Series products withstand temperatures up to 150°F, even in dark colors, so they won’t warp from sun exposure.
Color That Stays Put
Andersen 100 Series colors won’t fade, flake, blister or peel, so there is no exterior painting to put on the calendar.
A New Double-Hung
Andersen added a 100 Series double-hung in September 2025. Both sashes open and tilt in, so you can wash the outside glass from inside.
Styles
Window Styles at a Glance
Andersen offers the 100 Series in seven window types. These are the ones we order, with our notes on where each one works well.
| Style | How it opens | Where we often use it |
|---|---|---|
| Single-hung | The lower sash slides up; the upper sash stays fixed. | Bedrooms and living areas where you want a traditional look. |
| Double-hung | Both sashes slide and tilt in for cleaning. | Upper floors, where washing the outside glass from inside matters most. |
| Casement | Hinged at the side and cranks outward. | Over a kitchen sink or anywhere a crank is easier to reach than a sash. |
| Awning | Hinged at the top and opens outward. | Bathrooms, basements and below a picture window for ventilation. |
| Gliding | One sash slides sideways along a track. | Wide, short openings, such as over a counter or in a daylight basement. |
| Picture | Fixed; it does not open. | Framing a long view without a sash in the way. |
| Specialty shapes | Fixed shapes built to your opening. | Gable ends and above doors; see picture & specialty windows. |
Opening descriptions are general; the right style for each opening is settled during your in-home estimate.
Options
Colors, Glass and Grilles
Andersen offers the 100 Series in five exterior colors. Interiors come in a matte White, Sandtone, Dark Bronze or Black, and Andersen pairs the darker interiors with a matching exterior, so a Black interior comes with a Black exterior.
Glass
Andersen’s 100 Series glass choices include Low-E, Low-E SmartSun™, Low-E Sun and Low-E PassiveSun®, and each is available with HeatLock® coating. HeatLock is applied to the room-side surface of the glass, where it reflects heat back into the home and improves the window’s U-Factor. We help you match the glass to the room: a sun-control glass on a hot west wall, for example, and a passive-solar glass where you want winter sun.
Grilles and hardware
For a divided-lite look, Andersen offers grilles between the glass and simulated divided light. Andersen’s 100 Series product guide lists casement and awning hardware in Antique Brass, Black, Dark Bronze, Sandtone, Satin Nickel and White.
Joining windows on site
Every window we order is an individual unit. When an opening calls for several windows side by side, our crew joins the individual units on site to fill it.
Our Guidance
Why the 100 Series Suits Mountain Homes
Mountain homes see wide temperature swings in a single day: a south or west wall can bake in afternoon sun and then cool quickly after dark. A frame that expands and contracts less holds its seals and its shape better through those cycles. In extreme temperature swings Fibrex performs twice as well as vinyl, and that is the main reason we recommend the 100 Series for sun-struck elevations.
Dark exterior colors are popular on modern and farmhouse homes in our area, and they run hot in summer sun. The 100 Series is rated for those temperatures in dark colors too, so you can choose Black or Dark Bronze without worrying about warping. The 100 Series is a great fit for modern and modern farmhouse homes, whether you are replacing, remodeling or building new.
On energy, 100 Series products are available with options that make them ENERGY STAR® certified throughout the U.S. Certification depends on the glass you choose and where you live, so we configure each order for our climate zone rather than assume every window qualifies.

Questions
Frequently Asked Questions
What is Fibrex?
Fibrex is Andersen’s composite of wood fiber and thermoplastic polymer. It contains 40 percent reclaimed wood fiber by weight and is twice as strong as vinyl. It is the material of every 100 Series window and patio door.
What is the difference between the 100 Series and the 400 Series?
The 100 Series is Fibrex composite inside and out, with a factory-finished interior that never needs painting. The 400 Series is primarily wood, with a natural wood interior and a Perma-Shield® vinyl exterior, and it comes in seven exterior colors to the 100 Series’ five. Our 400 Series page has a side-by-side table.
Does the 100 Series come in double-hung?
Yes. Andersen introduced the 100 Series double-hung on September 16, 2025. It is available up to 4 feet wide and 7 feet 5-1/2 inches high, in custom sizes in 1/8-inch increments.
What warranty comes with 100 Series windows?
On the 100 Series, Andersen’s Owner-to-Owner limited warranty covers glass for 20 years and non-glass parts for 10 years, and it transfers to later owners; see Andersen’s warranty for full terms. Our own workmanship warranty covers the installation.
Are 100 Series windows ENERGY STAR certified?
They can be. Andersen offers options that make them ENERGY STAR certified throughout the U.S., and the glass decides it. Under ENERGY STAR Version 7.0, most of our service area is in the North-Central zone (U-factor 0.25 or lower, SHGC 0.40 or lower); Polk County is in the South-Central zone (U-factor 0.28 or lower, SHGC 0.23 or lower).
How much do Andersen 100 Series windows cost?
Price depends on the size, style and glass of each window and on the installation. Your exact number comes from a free, in-home estimate, and the price we quote is the price you pay.
