Andersen is the name people reach for when they want a premium, nationally recognized window and are willing to pay for the material and the brand behind it. Its calling card is Fibrex — a proprietary composite of wood fiber and polymer that's more stable and lower-maintenance than vinyl while carrying a richer, more substantial look — alongside genuine wood and clad-wood lines. For a Millbrae home, and especially the period houses up in the Highlands where a window's proportions and finish matter, Andersen's higher-end positioning fits. And with the city under the SFO flight paths, Andersen's insulated units can be built with the acoustic glass that counts here. Bay Area Siding Company installs Andersen across Millbrae.

Fibrex and the Andersen lines

Andersen's range sorts by material and tier:

• 100 Series — full-Fibrex composite, Andersen's most accessible line, with clean sightlines and low maintenance; a strong value entry into the brand.
• 400 Series — clad-wood with a Fibrex or wood interior and a durable exterior; the widely-specified mainstream line balancing warmth and performance.
• A-Series — the architectural, top-tier line, with the deepest range of styles, finishes, and historically informed profiles — the one to look at for a high-design or period Highlands home.

That laddering lets you buy into Andersen's look and warranty at the tier your project justifies, from a value Fibrex changeout to an architectural clad-wood installation.

Why Fibrex suits a Millbrae home

Fibrex was engineered to hold up where wood struggles and vinyl looks thin. It resists the swelling and rot that damp climates provoke in solid wood, and it's more dimensionally stable than vinyl through temperature swings, so frames stay tight. In Millbrae's cool, marine-influenced climate — a moisture climate more than a heat one — that stability and low upkeep are genuine advantages, and the composite carries a narrower, more refined frame than most vinyl, which reads better on a house where appearance is part of the decision.

Andersen and the SFO noise factor

Because much of Millbrae sits under SFO's flight paths, the glass package is where the real noise gains live — windows are the weakest point in a wall for sound. Andersen offers laminated glass options whose acoustic interlayer damps the frequencies aircraft produce, and dual-pane insulated units can be configured to disrupt overflight noise more effectively than standard matched glass. As always, the glass only performs if the install is tight and well-flashed, since sound follows the same gaps air and water do. Millbrae's General Plan sets interior-noise goals for homes in the higher contours; how far to push the acoustic spec depends on where your home sits relative to the flight paths, which we assess before ordering.

Where Andersen fits — and where it might not

Andersen is for the homeowner who wants a premium, recognized brand and either the low-maintenance Fibrex composite or a genuine clad-wood look. If your priority is the highest-end wood and fiberglass architectural window, compare Marvin. If a California-made, efficiency-first vinyl at a lower price makes more sense, look at Anlin; for the broadest West Coast material range, Milgard; and for another national brand spanning vinyl to wood, Pella. Weigh them all at the window replacement hub.

Permits, energy, and the hillside note

Millbrae requires a building permit for window replacement, and because a window swap is an alteration under the Energy Code, a Title 24 form is part of the submittal — the City of Millbrae Building Division reviews it and we handle the paperwork. Title 24 sets the maximum U-factor and SHGC for replacement windows, and those figures move by climate zone and code cycle, so we confirm the units meet the code in force at permit time rather than quoting fixed numbers.

If your home is on the western hillside near the Highlands or Mills Estates, parcels the 2025 State Fire Marshal maps place in fire hazard severity zones (Central County Fire Department's area) can, where an altered opening falls under Chapter 7A, require multi-pane glazing with a tempered pane. Andersen units can be built with tempered glass, and whether the requirement applies depends on your parcel and whether the work is repair or alteration, which we confirm with the City before ordering. Flatland homes toward El Camino Real generally aren't affected.

What affects the cost

Andersen sits at the premium end, and the quote moves with the series and material (100 Series Fibrex to A-Series clad-wood is a real spread); the number and size of openings; the glass package and how far you take the acoustic/laminated spec; retrofit versus new-construction method; any hillside tempered-glazing requirement; the condition of the existing framing, since rot repair adds scope; and access. We price it after measuring.

FAQ

What is Fibrex, and why does Andersen use it? Fibrex is Andersen's composite of wood fiber and polymer. It resists the rot and swelling that affect solid wood in damp climates and is more stable than vinyl, with a narrower, more refined frame — a good fit for Millbrae's marine climate and for homes where appearance matters.

Can Andersen windows cut the aircraft noise from SFO? They can help meaningfully. Andersen offers laminated acoustic glass and insulated configurations that target overflight frequencies, and the benefit depends on a tight air-seal. How far to push the spec depends on where your Millbrae home sits relative to the flight paths, which we assess before ordering.

Which Andersen series is right for a period Highlands home? The A-Series is the architectural line with the deepest range of historically informed profiles and finishes, so it's usually the one to look at for a high-design or period home. For a more accessible entry into the brand, the 100 Series full-Fibrex is a strong value. We'll match the tier to your home and budget.

Do I need a permit for Andersen windows in Millbrae? Yes. The City of Millbrae Building Division reviews window replacement, with a Title 24 form part of the submittal. We prepare and file it.
