Andersen Fibrex Technology

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.

Fibrex Composition:
Reclaimed Wood Fiber 40%
Thermoplastic Polymer 60%

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.

Wood Fiber Core
Structural strength, dimensional stability
Polymer Matrix
Moisture resistance, UV protection
Extruded Finish
Seamless surface, zero maintenance

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.

Thermal expansion coefficient: 0.003 in/ft
(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.

Water absorption: Less than 1%
(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.

UV resistance: Excellent
(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.

Structural strength: 2x vinyl
(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
