Andersen finally added a double-hung option to its 100 Series line. Until now, this line only came as a single-hung window, meaning only the bottom glass panel could slide up and down while the top sash remained fixed in place.
At Michigan Screen, we wanted to give you the candid, unvarnished truth about this new release. We tested this window from top to bottom, checking out its build, price, and the actual problems we’ve run into during installations.
Here’s what you need to know before you buy.
Andersen 100 Series Double-Hung Window Product Overview
The new Andersen 100 Series Double-Hung Window lets both top and bottom panels slide open and tilt inside. This makes cleaning a breeze, especially on second-floor windows where nobody wants to haul a ladder outside.
Like the rest of the 100 Series, it’s made from Fibrex, Andersen’s blend of wood fiber and plastic, instead of cheap vinyl. This gives you a high-end look without the huge price tag of real wood.
Before we get into the specifics, it’s worth talking about how this window fits into the broader lineup Andersen offers, because a lot of homeowners we talk to at Michigan Screen don’t realize how many tiers exist between entry-level and premium.
The 100 Series has always been the value play. It’s the option you choose when you want the Andersen name and the Fibrex material without stretching into custom pricing.
Adding a double-hung configuration was a logical next step, since single-hung windows have felt dated for a while now, especially compared to what competitors in the same price range offer.
Benefits of Andersen 100 Series Double-Hung Windows
There’s a lot to like here, and we want to give credit where it’s due before we get into the drawbacks.
Fibrex Material
The main reason to buy a 100 Series window is the Fibrex composite material. It’s a proprietary blend of reclaimed wood fiber and thermoplastic polymer.
The wood fiber gives it a rigidity closer to wood, while the polymer component keeps it from absorbing moisture, rotting, or attracting pests. You get the structural feel of a wood frame without needing to paint, seal, or replace rotted sills every few years.
If you put one right next to a standard vinyl window, you can instantly see the difference. Fibrex is thicker and much stronger than vinyl, allowing the 100 Series to support larger glass panels and slimmer sightlines without flexing under the weight.
Because it’s stronger, Fibrex won’t warp, crack, or bend as it ages. It prevents the common vinyl problem where old frames twist out of shape and stop closing properly.
Matte Paint Finish and Coating
The outside finish on this window is a thick, low-luster paint that’s sturdier than classic vinyl. It doesn’t scratch, dent, or ding easily. If you want colored windows, we’ll pick the 100 Series over vinyl every single time. The paint simply lasts longer.
We’ve also noticed that the matte texture does a better job of hiding small imperfections. A glossy finish tends to highlight every minor scuff, water spot, or dust, while the coating on the 100 Series keeps your frames looking clean year after year.
Andersen Warranty
Part of what you pay for with Andersen is top-tier manufacturer support. They have one of the most reliable warranties in the industry.
The 100 Series includes their fully transferable Owner2Owner Limited Warranty, a great selling point for future home value. It covers glass seal failures for 20 years, Fibrex frame components and hardware for 10 years, and factory exterior finishes against peeling or flaking for 10 years.
High-Quality Glass Package
Even though the 100 Series is Andersen’s cheapest option, it uses the exact same Low-E4 glass package found in their premium 400 Series and A-Series lines.
Most brands cut corners on budget windows with basic dual-pane glass, but Andersen makes argon gas insulation standard for superior year-round energy savings.
This multi-layer coating reflects summer heat and holds in winter warmth to lower energy bills, blocks UV rays to protect furniture from fading, dampens outside noise, and uses a sunlight-activated exterior coating to reduce water spots by up to 99%.
Block-and-Tackle Balance System
The mechanism that lets the sashes glide up and down is a block-and-tackle balance system, which is pretty much the gold standard. Andersen uses this exact same setup in their pricey windows, so you aren’t getting cheap, downgraded parts just because you bought their budget line.
Quiet Operation
Thanks to that balance system, opening and closing the window feels practically effortless. It glides smoothly and stays completely quiet. There are no grinding noises, no stubborn sticking, and no loud clunks when you raise or lower a sash.
Long-Lasting Construction
Between the Fibrex frame, the thick paint finish, and the proven balance system, you get a window built to stand the test of time. It’s a solid piece of engineering, as long as Andersen fixes the kinks we’ll cover below.
Contemporary Frame Profile
Many of Andersen’s other windows have a chunkier, more traditional style. In contrast, the 100 Series features thinner, sleeker frames that let in more light.
That slim design is perfect if you’re going for that trendy, all-black modern look that so many homeowners are loving these days. It gives your home a clean, updated feel without looking outdated.
Andersen 100 Series Double-Hung Window Functions
The main reason to pick the Andersen 100 Series Double-Hung is convenience, and this one really delivers. Both the top and bottom panels slide on their own and tilt inward for cleaning. You can wash both sides of the glass from inside your home, a huge plus for upper floors.
Using the window is pretty simple overall, but you do need to be a little careful when lowering the panels to the bottom. If you force them or move too fast, the internal sliding mechanism can pop out of track.
Once you get the hang of it, it moves effortlessly, giving you an easy-to-clean Fibrex window that looks and works great.
Drawbacks of Andersen 100 Series Double-Hung Windows
Now for the most important part. We visited Andersen’s testing facility and watched them blast this window with high winds, pressurized water, and extreme structural stress. On paper, it passed every test with flying colors.
Real life, however, is a different story. Installing these on actual homes has revealed a whole bunch of unexpected problems, not just for us as installers, but also for homeowners who’ve had them for a few months.
Honestly, there have been enough warranty issues that it’s changed how comfortable we are recommending it right now.
Rattling in the Sash Play
The first issue is a looseness in the sashes. There’s nearly a 3/16 of an inch of sloppy front-to-back play with the sashes. That means every time you open or close the window, it feels cheap and shaky. And when a strong breeze hits, it can actually rattle inside your wall.
When you spend good money on brand-new windows, they shouldn’t feel flimsy right out of the gate. We’ve seen this on multiple projects, and it’s a real problem.
Tilt Latch Design
The tilt latches sit at the top of the sash, which isn’t our favorite placement to begin with. We’d prefer them built directly into the main lock, but the real issue is how they’re shaped. They have sharp, square edges that block the window from closing unless you manually pull them in first.
The problem is, people forget to do this all the time. If you slam or push the window shut without pulling those latches back, they snap right off.
You don’t see this kind of design flaw on similar vinyl windows or on Andersen’s other models, and it’s causing huge headaches for homeowners who keep accidentally breaking them.
Visible Weatherstripping
There’s a white or gray weatherstrip that runs down the middle of the window. On an all-black frame, this light-colored seal sticks out like a sore thumb. Even worse, it’s prone to kinking as the window gets used, making it look worse as time goes on.
Our demo unit looks clean because it’s new, but we’ve already seen this become a cosmetic issue on installed windows.
Price Point: 15–20% Premium for an Entry-Level Product
The 100 Series is supposed to be Andersen’s affordable option, but this new double-hung version costs 15% to 20% more than the single-hung model.
That might not sound like much, but it bumps this window into a higher price tier, where it competes directly with actual wood windows.
If we have to choose between genuine wood and entry-level Fibrex at a similar price, wood wins every time. Lower-cost vinyl options and higher-end composite or wood windows frame the market clearly, but this window sits awkwardly in the middle.
Spending wood-window money usually warrants getting actual wood, unless the low-maintenance appeal of Fibrex is a bigger priority than authenticity. Ultimately, homeowners shopping for a budget option don’t expect to pay a premium that puts them in wood-window territory, and that’s a tough sell.
New Product With Potential Kinks Still to Be Worked Out
This is our absolute biggest concern. This window has been on the market for less than eight months, which is practically brand-new in the window industry. First-generation products almost always have unexpected bugs, and it usually takes a round or two of design tweaks to fix them.
Andersen will likely address these flaws, whether that means redesigning those fragile tilt latches, tightening up the shaky balance system, or swapping out the unsightly weatherstripping.
We don’t know their exact plans, but experience tells us that fixes are almost certainly coming within the next six to twelve months.
When Andersen 100 Series Double Hung Windows Are the Right Choice
Even with those concerns, this window makes sense for certain situations.
Upgrading Second-Floor Windows
If you’ve got older, builder-grade windows on the second floor of your home, this window solves a real problem: cleaning windows you can’t easily reach.
The tilt-in feature lets you safely wipe down both sides of the window from inside your room. This alone makes this window worth considering for second-floor replacements, even with its current flaws.
Looking for a Matte Finish
If you’re drawn to Andersen’s modern matte finishes, the 100 Series is one of the most cost-effective ways to get those premium color choices without forcing you into custom, luxury price points.
Because standard vinyl windows usually only come in basic glossy white or beige, having access to factory-applied matte colors, like dark bronze, black, or deep gray, is a huge selling point.
Want Andersen Windows at a Lower Price Point
If your priority is simply having the Andersen name on your windows without paying for one of their premium lines, this is a less expensive way to do that, even with the double-hung premium factored in.
Pump the Brakes on Andersen 100 Series Double-Hung Windows
Here’s our honest take: we don’t think you need to rush into this window right now. Between the sash rattle, the tilt-latch design, the weatherstripping issues, and the price, this product has enough rough edges here that we’d rather see Andersen work through them first.
Our recommendation is to hold off for six to twelve months if you can. Keep an eye on other options in the meantime, and let Andersen make the adjustments we expect are coming.
If you’re set on this window and it fits your budget and your needs today, just go in with your eyes open. We don’t think this is a bad window; it’s a promising design that hasn’t quite finished growing up yet.
Once Andersen tightens the sash tolerances, redesigns the latches, and cleans up the weatherstripping, it could easily become one of the better values in the Fibrex double-hung category.
