When the Window Has to Match the Architecture
You’re building a custom home on Crystal Lake. Restoring a century-old farmhouse. Renovating a mid-century modern with glass walls. The architect specified a specific profile, a specific color, a specific wood species. And every “standard” window you’ve looked at so far comes back with a list of limitations.
The Andersen E-Series is where those limitations go away. It’s the top of Andersen’s lineup — the architectural collection that grew out of Eagle Windows after Andersen acquired them in 2005. Extruded aluminum cladding (nearly three times thicker than roll-form aluminum used by competitors). Ten-plus wood species plus custom sourcing. Fifty-plus exterior colors plus custom color matching. Custom sizes in 1/8-inch increments. Twenty-five specialty shapes. If you’ve ever been told “we can’t do that” on a window project — the E-Series is the answer.
Why the E-Series Exists — and When It’s the Right Call
The E-Series isn’t for every project. Most McHenry County homes are better served by the 400 Series or A-Series. But when an architect, a historic home, or a custom build demands something that standard windows can’t deliver, this is where you end up. Here’s what makes it different.
Extruded Aluminum Cladding — Not Roll-Form, Not Bent Sheet Metal
Every other major window brand uses roll-form aluminum on their clad exteriors — essentially bent sheet metal. Andersen’s E-Series uses extruded aluminum, formed by pushing heated aluminum through a die to create a dense, consistent cross-section. It’s nearly three times thicker than roll-form. The result is a stronger, more structurally capable exterior with tighter tolerances — which matters a lot when the windows are custom-sized and architecturally detailed.
This is why Andersen bought Eagle Windows back in 2005. Eagle had the extruded aluminum technology no other Andersen line had. That acquisition became the E-Series in 2012, and nothing else in the Andersen catalog uses this exterior.
10+ Wood Species — Plus Custom Species Sourcing
Pine, Oak, Walnut, Hickory, Vertical Grain Douglas Fir, Mixed Grain Douglas Fir, Maple, Alder, Mahogany, Cherry. That’s the standard offering. If you’re restoring a historic home and need to match existing trim in a species that isn’t on the list, Andersen will source it and match the stain or paint for the E-Series — something no other Andersen line offers. On the finish side: 11 interior wood finishes, 14 paint colors, and custom stain matching available.
The custom species sourcing is the tell. When a client tells me they’re restoring a 1920s home with original quarter-sawn white oak trim, the E-Series is the only line I can honestly promise will match.
50+ Exterior Colors Plus Custom Color Match — and 7 Anodized Finishes
The E-Series ships with 50+ standard exterior aluminum colors. If none of those match what the architect spec’d or what your siding already is, Andersen will custom-mix a color. You can combine up to four different colors on a single unit — frame, sash, divided light grilles, accessory metals. There are also seven anodized finishes available as an alternative to painted aluminum. On the hardware side: 21 finish options, more than any other Andersen series.
Most homeowners don’t need 50 colors. But when the house already has a specific exterior trim color and the architect wants the windows to disappear into it, this is where you land.
Custom Sizing in 1/8-Inch Increments — 25 Specialty Shapes
Replacement projects on older homes run into one problem over and over: the openings aren’t standard. A wall that’s settled. A historic rough opening that never matched a catalog. The E-Series is built in 1/8-inch increments on every dimension, so the window fits the opening — not the other way around. Add 25 specialty shapes (arches, circles, trapezoids, triangles, custom geometrics) plus nine regular window types, and you can build a full-wall assembly where every unit was made for its exact location.
When you walk a historic home, you can tell which windows were replaced with “close enough” sizes — the filler strips and caulk lines give it away. The E-Series is how you avoid that.
Triple-Pane Glass and VeriLock Security Sensors — Features No Competitor Has
The E-Series is available with triple-pane glass, Low-E coatings, Argon or Krypton gas fill, SmartSun for solar heat gain control, and HeatLock for interior heat retention. For McHenry County’s Climate Zone 5A winters, that combination is ideal. The E-Series is also the only window in the industry with VeriLock integrated security sensors built into the lock itself — they connect to home security systems and let you confirm every window is locked without walking the house. This is exclusive to Andersen.
VeriLock is one of those features you don’t think you need until you have it. Then you wonder how you ever lived in a house without knowing every window was locked before you went to bed.

Andersen Window Comparison — Where the E-Series Fits
The E-Series is top-of-line. That doesn’t mean it’s the right answer for every home. Here’s how the four main Andersen series compare so you can see exactly when the E-Series is worth it — and when the A-Series or 400 Series is the smarter call.
| Feature | 100 Series | 400 Series | A-Series | E-Series Top of Line |
|---|---|---|---|---|
| Frame Material | Fibrex composite | Wood + Perma-Shield vinyl | Wood + fiberglass / Fibrex / Perma-Shield | Wood + extruded aluminum |
| Interior Wood Species | N/A (Fibrex) | Limited (primarily pine) | 6 species | 10+ species + custom sourcing |
| Exterior Colors | 5 | Limited | 11 | 50+ plus custom color match + 7 anodized finishes |
| Hardware Finishes | Limited | Limited | 12 | 21 — most in the Andersen lineup |
| Custom Sizing | Standard sizes | Standard sizes primarily | 1/8″ increments | 1/8″ increments, every dimension |
| Specialty Shapes | Limited | Limited | 34+ | 25 shapes, custom grille patterns |

| VeriLock Security Sensors | — | Available | Available | Available (industry-exclusive to Andersen) |
| Best For | Upgrading from vinyl | Andersen bestselling value | Premium remodels, custom homes | Architect-specified, historic restoration, custom new construction |

Notes From the Field — What We Actually Install
I’ll be straight with you: we don’t install the E-Series on most projects. It’s the wrong answer for the vast majority of McHenry County remodels. The E-Series is what we turn to when the project is architect-specified, the home is a custom build, or we’re restoring a 1920s Craftsman with original quarter-sawn white oak trim that has to be matched. For those projects, the 50-plus exterior colors, 10-plus wood species with custom sourcing, and 1/8-inch custom sizing are what make the project possible.
The extruded aluminum cladding is the structural story. It’s nearly 3 times thicker than the roll-form aluminum most competitors use, which means tighter tolerances on custom sizing and a more durable exterior. When we’re working off architect drawings with 34 custom window openings, 1/8-inch increments matter. That’s how we avoid filler strips at the frame and caulk lines that give away a retrofit.
We’ve installed E-Series on lake homes along the Fox River and on historic properties in downtown Crystal Lake. The custom wood species sourcing is the feature nobody else in Andersen’s lineup offers — if the home has trim in a regionally specific species, we can order the window to match. It’s rare work. But when a client needs it, nothing else in the catalog does the job.

Frequently Asked Questions
What makes the E-Series different from the A-Series?
The A-Series is Andersen’s premium line with three exterior cladding options (fiberglass, Fibrex, Perma-Shield vinyl), six wood species, and 34+ specialty shapes. The E-Series is the architectural top tier — extruded aluminum cladding (nearly three times thicker than roll-form used by competitors), 10+ wood species plus custom sourcing, 50+ standard exterior colors plus custom color match, seven anodized finishes, 21 hardware finishes, and 25 specialty shapes built to 1/8-inch increments on every dimension. The E-Series is what you choose when the project requires something the catalog can’t deliver — historic restoration, custom new construction, or architect-specified matching.
Where did the E-Series come from?
It started as Eagle Windows — a brand founded in 1977 that introduced the first aluminum-clad wood casement window. Andersen acquired Eagle in May 2005 to bring extruded aluminum cladding into the Andersen portfolio. In 2012, Eagle was relaunched as the E-Series under the Andersen Architectural Collection. The extrusion technology and custom capability that defined Eagle are now what defines the E-Series.
Can I get a custom wood species that’s not on Andersen’s standard list?
Yes — only on the E-Series. Andersen will source custom wood species and match the stain or paint to your existing woodwork. This is unique to the E-Series. It’s also why the E-Series is the go-to line for historic restoration: when your original trim is quarter-sawn white oak or a regionally specific species, the E-Series is the only Andersen line that can match it.
What warranty comes with the Andersen E-Series?
E-Series warranty coverage includes 20 years on standard glass packages (10 years on decorative glass), 20 years on exterior painted aluminum finish in non-coastal zones (10 years coastal), 10 years on interior wood when properly sealed per Andersen specifications, and 10 years on hardware, weatherstripping, and screens. Because IHC is an Andersen Elite Certified Contractor, you also get an exclusive 2-year installation warranty on the work itself. Both warranties are fully transferable to the next homeowner through Andersen’s Owner-to-Owner program if you sell the home.
Is the E-Series worth it if I’m doing a regular remodel, not a custom home?
Probably not, and that’s the honest answer. For most replacement projects in McHenry County, the A-Series gets you 80 to 90 percent of the E-Series customization at a different investment level. The E-Series is right when: you’re building new custom construction, restoring a historic home with non-standard openings, matching original wood species that aren’t on the standard list, or working from architect drawings that specify an aluminum-clad profile that standard Andersen lines don’t offer. The in-home consultation is where we figure out which one actually fits your project.
Does the E-Series meet ENERGY STAR requirements for my McHenry County home?
Yes. Most E-Series products meet current ENERGY STAR criteria, and triple-pane configurations with Low-E, Argon or Krypton gas, and HeatLock are the best solution for meeting ENERGY STAR requirements in the Northern climate zone where McHenry County sits. Actual U-Factor, SHGC, and VT values are NFRC-certified per unit and depend on the specific glass package you choose. We match the glass spec to your home during the consultation — SmartSun for south- and west-facing exposure, HeatLock for heat retention on north-facing openings.
