Comparing Key Features and Performance
Now that we’ve covered the basics of each window line, let’s do a detailed comparison of their main features and performance specs:
Frame Materials
- Simonton – Vinyl frame construction, fusion-welded corners
- Andersen – Fibrex composite material (40% vinyl, 60% reclaimed wood fiber)
The Fibrex frames give Andersen an advantage in strength, dent-resistance, and insulation. Vinyl is more prone to expansion and contraction.
Glass Options
- Simonton – Clear, obscure, and tinted double-pane glass units available
- Andersen – Clear double-pane units with High-PerformanceTM Low-E coating
Both offer energy efficient double-pane glass. Simonton has more glazing options while Andersen glass maximizes visibility and natural light transmittance.
Energy Efficiency
- Simonton – U-factor ranges from 0.27 to 0.31 depending on glass chosen
- Andersen – U-factor of 0.27 standard across all units
Lower U-factors indicate better thermal insulation. Andersen wins slightly on energy efficiency specifications.
Visible Light Transmittance
- Simonton – VLT ranges from 21% to 65% depending on glazing
- Andersen – High VLT of 62% standard for clear glass
The High-PerformanceTM Low-E glass gives Andersen very high visible light transmittance for maximum daylight and solar heat gain.
Air Leakage
- Simonton – Air infiltration rating around 0.18 cfm/ft2
- Andersen – Air leakage rating as low as 0.01 cfm/ft2
Significant advantage for Andersen here. The Fibrex material and tighter construction results in less air flow for improved efficiency.
Exterior Color Options
- Simonton – White, tan, clay, black standard colors
- Andersen – 15 exterior color options, custom colors also available
Both offer flexibility in exterior colors to match your home’s aesthetics. Andersen has a wider selection of standard color choices.
Warranties
- Simonton – Limited lifetime warranty on vinyl and glass
- Andersen – 20-year coverage on glass, 10 years parts and labor
The lifetime vinyl and glass warranty from Simonton is strong but Andersen still provides lengthy 20 and 10-year warranties.
Pricing
- Simonton – Moderately priced, affordable mid-range option
- Andersen – Higher-end pricing but still lower cost composite line for the brand
Simonton 6500 series windows will be the less expensive option. But Andersen 100 series offers good value compared to other composites.
