100, 200, 400 Series & A-Series. Fibrex Composite & Real Wood Interiors. Lifetime Glass Warranty on 400 Series. Licensed OR #241979.
Andersen is one of the most recognized window brands in the country, and for good reason — their lineup runs from affordable entry-level options all the way to premium wood-clad units. VResh Construction has installed and replaced Andersen windows throughout the Portland metro for nearly two decades.
Here’s what sets us apart: we don’t push any single brand. When you call us, Vlad will look at your home, your goals, and your budget — then tell you honestly whether Andersen is the right fit or whether another brand would serve you better. No commission pressure. Just a straight answer.
Whether you’re replacing a single failed unit or doing a whole-house upgrade to an Andersen 400 Series or A-Series, we handle the full installation — removal, disposal, flashing, and finish carpentry — with no subcontractors and no surprises on the final invoice.
The Andersen Lineup — What Each Series Delivers
|
100 Series (Fibrex)
Entry-Level Durability
|
Andersen’s entry-level line uses their proprietary Fibrex composite — a mix of wood fiber and polymer that is twice as strong as vinyl. Low maintenance, good energy performance, and a narrower price point than the upper series. The 100 Series does not have a wood interior — Fibrex throughout. A solid choice when durability and budget take priority over aesthetics, and a wood interior is not required. |
|
200 Series (Perma-Shield)
Affordable Wood Interior
|
Vinyl-clad exterior with a pine interior. The 200 Series is Andersen’s most affordable wood-interior option — paintable inside, durable outside, available in a wide range of sizes. A practical mid-range pick for budget-conscious Portland homeowners who want the warmth of real wood inside without the premium price of the 400 Series. |
|
400 Series (Woodwright)
Flagship — Most Common in Portland
|
Andersen’s flagship line and the series most commonly specified in Portland renovation projects. A wood interior with an aluminum-clad exterior delivers the warmth of real wood inside and weather resistance outside. Strong energy ratings, a lifetime warranty on glass, and wide availability in Portland make this the default Andersen choice for most projects. This is the series we install most frequently. |
|
A-Series (Architectural)
Premium Design Flexibility
|
Andersen’s premium offering. The A-Series emphasizes design flexibility — custom sizes, a wide color palette, flush-frame interiors, and ultra-slim sightlines. Ideal for high-end renovations, modern builds, or historic restorations where the window is part of the visual statement. Meaningfully higher price point than the 400 Series — Vlad will give you an honest assessment of whether the upgrade is worth it for your specific project. |
|
E-Series (Eagle)
Natural Wood Performance
|
Wood windows with a variety of cladding options — aluminum or fiberglass exterior, a wide range of interior wood species. The E-Series prioritizes natural wood character inside and out. Best for homeowners who want authentic wood performance and appearance and are prepared to maintain a wood exterior over time. |
|
Renewal by Andersen
Independent Installation Note
|
Andersen’s own replacement division — full-frame replacement units sold and installed exclusively through their dealer network. Note: VResh is an independent licensed contractor, not a Renewal by Andersen dealer. We can replace your windows with Andersen products at competitive pricing with the same quality result, without the Renewal by Andersen markup. |
Why Andersen Performs in Portland’s Climate
Portland homeowners replacing aging vinyl or wood windows need to understand what they’re getting into — not just the brand, but the specific material and why it matters for this climate. Here’s what sets Andersen apart.
Fibrex Composite — Stronger Than Vinyl
Andersen’s proprietary Fibrex composite — used in the 100 Series and Renewal by Andersen line — is a blend of wood fiber and thermoplastic polymer. It is twice as strong as vinyl and more dimensionally stable across Portland’s temperature range. While Fibrex does not match the paint retention of Marvin’s Ultrex fiberglass, it outperforms standard vinyl on all key durability metrics and carries a meaningful price advantage over premium fiberglass products.
Wood Interiors — 400 Series and Above
The 400 Series, A-Series, and E-Series all feature real wood interiors — not vinyl that resembles wood. For Portland homeowners replacing windows in Craftsman bungalows, colonial revival homes, or any residence where the interior window character matters, the wood interior is the detail that makes Andersen worth the premium over vinyl-only alternatives. The aluminum-clad exterior on the 400 Series protects the wood interior from Portland’s sustained moisture season.
Energy Performance in Portland’s Climate
Portland’s climate — 7–8 months of sustained moisture, temperature swings between freezing and 90°F+, and UV exposure on south-facing elevations — demands strong window performance. Andersen’s 400 Series and A-Series both carry ENERGY STAR certification for the Northern climate zone and deliver U-factors well below the code minimum for Oregon. The aluminum-clad exterior on the 400 Series holds up well across Portland’s seasonal range without the paint maintenance required by wood-exterior alternatives.
Glass Warranty — Lifetime on 400 Series
Andersen backs the 400 Series with a lifetime warranty on glass seal failures — the fogged glass issue most commonly seen in aging Portland windows. This is one of the strongest glass warranties in the industry at this price point. The A-Series carries a 20-year warranty on glass. Warranty documentation is provided at project completion on every VResh installation.
