The 100 Series is built from Andersen's exclusive Fibrex® material — a composite of roughly 40% reclaimed wood fiber and 60% thermoplastic polymer. It's twice as strong as vinyl, resists fading, and holds dark colors beautifully, giving you a clean, modern window at a smart price.
Emerald City Energy is an authorized Andersen installer serving the Puget Sound since 1997. Here's what sets the Andersen 100 Series apart.
Fibrex frames are rigid and durable, allowing slimmer profiles and more glass than ordinary vinyl windows.
Unlike vinyl, Fibrex holds rich, dark exterior colors without warping or fading in the Northwest sun.
Insulating frames and High-Performance™ Low-E4® glass help cut energy bills and block UV.
Fibrex reuses wood fiber that would otherwise be waste — strength with a smaller footprint.
A range of operating styles to fit every room, view, and architectural look — all available through Emerald City Energy.
