Composite Windows That Outlast Everything Else
40% reclaimed wood fiber + 60% thermoplastic polymer = 2x stronger than vinyl, more stable than wood, perfect for Houston's brutal climate.
What Makes Fibrex Different?
Most window materials make compromises. Vinyl is cheap but weak. Wood is strong but rots. Aluminum is durable but conducts heat like crazy.
Andersen spent decades developing Fibrex to eliminate those compromises. It's not wood. It's not vinyl. It's something better.
The wood fiber provides strength and rigidity. Think structural support.
The polymer binds it together and makes it weather-resistant. Think protection.
Together, they create a material that won't warp, crack, rot, or corrode. Even in Houston.
How Fibrex Handles Houston's Climate
Extreme Temperature Swings
Houston goes from 50°F mornings to 100°F afternoons. Most materials expand and contract, creating gaps and stress. Fibrex barely moves.
(Vinyl: 0.005 in/ft, Aluminum: 0.013 in/ft)
90% Humidity
Wood rots. Steel corrodes. Vinyl stays stable but loses strength in heat. Fibrex's polymer coating makes it impervious to moisture while wood fiber provides structural integrity.
(Zero rot, zero swelling, zero degradation)
Brutal UV Exposure
Houston's sun bleaches cars in parking lots. Vinyl windows fade to chalky white in 10-15 years. Fibrex has UV stabilizers throughout the material, not just on the surface.
(No fading, no chalking, looks new decades later)
Storm Season
70mph+ wind gusts and driving rain. Fibrex's strength means frames don't flex or bow. Sealed tight, stays tight.
(No sagging on large windows, no stress cracks)

Why Choose Composite
- 2x stronger than vinyl: Large windows won't sag or bow over time
- Minimal thermal expansion: Frames stay tight, no seasonal gaps
- 30+ year lifespan: Outlasts vinyl by 10-15 years
- Zero maintenance: Never paint, never stain, never seal
- Won't fade or chalk: Looks new decades later
- Handles Houston humidity: Won't rot, swell, or corrode
- Premium feel: Solid, substantial, high-end
Consider Before Buying
- Higher upfront cost: 2-3x more than vinyl windows
- Limited brand options: Mainly Andersen (they invented it)
- Contains wood fiber: Though moisture-resistant, not 100% immune
- Longer ROI: Takes 10-12 years to recoup cost vs vinyl's 5-7
- Heavier than vinyl: Installation requires experience
