Andersen 100 Series Replacement Windows in Southlake & Dallas
The 100 Series is Andersen's budget-friendly line, made from its Fibrex composite material — which Andersen says is twice as strong as vinyl. RADIANT installs it across North DFW, and we'll tell you honestly how it compares with the other windows we carry.
See Andersen on display at our Southlake showroom — 500 N Kimball Ave #106, Southlake. Mon–Fri 8:00 AM – 5:00 PM.
Andersen 100 Series at a glance
The product line
What Andersen says sets the 100 Series apart
Everything below is how Andersen describes its own product. We'll show you samples in person so you can judge the frames, finish and hardware for yourself.
Twice as strong as vinyl
Andersen says Fibrex is 2x stronger than vinyl and "retains stability and rigidity in all climates," so weathertight seals stay weathertight — where vinyl can expand in the sun and contract in the cold.
Rated for hot surfaces, even in dark colors
Andersen's product guide states Fibrex withstands temperatures in excess of 150°F, even in dark colors, and blocks thermal transfer nearly 700 times better than aluminum.
Color that never needs painting
Andersen describes a matte finish that "won't fade, flake, blister or peel." Exterior colors: White, Sandtone, Terratone, Dark Bronze and Black. Interior: White, Sandtone, Dark Bronze and Black.
Made for replacement openings
Custom sizes in 1/8" increments, with no-flange and insert frame options for remodeling and replacement, plus standard and custom grille patterns.
Looking at 400 Series or E-Series?
Andersen also lists the 400 Series, E-Series and Woodwright double-hung for replacement. The 200 and 400 Series use a wood core clad in vinyl rather than Fibrex.

Energy & glass
Glass choices that matter in a North Texas summer
Andersen states that energy-efficient 100 Series products are available with options that make them ENERGY STAR certified throughout the U.S. The glass package is where most of the energy decision happens — and a sun-baked west wall in Southlake may call for something different than a shaded north window.
- Glass options: Low-E, SmartSun, PassiveSun, Low-E Sun and clear dual-pane, with HeatLock coatings available on several
- Fibrex frames that Andersen says block thermal transfer nearly 700 times better than aluminum
- Specialty glass: tempered safety glass and patterned glass such as Obscure, Reed and Satin Etch

Already have good windows but a hot room? Solar screens block 80–90% of Texas summer heat and can be a lower-cost first step.
Warranty
How Andersen's 100 Series warranty works
The 100 Series carries Andersen's Owner-to-Owner limited warranty, which Andersen says is transferable if you sell your home. Andersen's 100 Series product guide summarizes it as 20 years on glass and 10 years on non-glass parts, not prorated. Exclusions and conditions apply — read Andersen's warranty for your product.

Honest fit
Is the Andersen 100 Series right for your home?
Often a good fit if you…
- Want a step up from standard vinyl at a budget-friendly price point
- Like darker colors such as Dark Bronze or Black and want a frame rated for hot surfaces
- Want a frame that never needs painting
- Might sell in the next few years and value a transferable warranty
Worth comparing if you…
- Want a wood interior — ask about wood and clad-wood lines
- Want a fiberglass frame — compare Pella Impervia
- Have only a few failed panes in sound frames — new glass may be enough
Compare: Pella Impervia · Wincore · Anlin · All brands we install
Frames still sound? You may only need new glass.
If your windows are foggy or drafty at the glass but the frames are solid, replacing just the insulated glass is usually a smaller job than new windows. We'll tell you which you need — even if that means less work for us.
