Renewal by Andersen Fibrex Window Frames vs. Vinyl
Renewal by Andersen’s Fibrex® composite material combines the strength and durability of wood with the low maintenance qualities of vinyl, and won’t cause cracks in the joints from the freeze/thaw cycle
With a wide selection of color combinations and palettes, you can expect that there will be no yellowing, bleaching, or fading in the sun, even a decade after your window installation
Fibrex® material’s strength and durability makes for narrower frames. Narrower frames make for more glass in your window and less material obstructing your view of the outdoors
Fibrex® material has superior thermal insulating properties and when combined with Anderson® High-Performance™ Low-E4® glasses, it can help you save money on energy bills.
Our revolutionary Fibrex® windows will hold their shape without bowing, bending, or warping

Renewal by Andersen’s exclusive Fibrex® material is more durable and energy efficient than both wood or vinyl windows, we can guarantee that. More than anything, while the seasons may change, we are committed to standing by our window replacement product, today, tomorrow, and well into the future.
