Keep reading for an in-depth examination of the factors that set these two brands apart. Major Differences Between Interstate and Andersen While Interstate and Andersen both manufacture quality windows, there are some noteworthy differences between the two brands: Frame Materials The main difference is the window frame and sash materials used: Interstate: Vinyl frame and sashes on all products Andersen: Fibrex composite, vinyl, wood, or wood-clad on different window lines Vinyl is affordable and offers good durability and low maintenance. However, Andersen's Fibrex material provides superior strength and resistance to temperature extremes. Their wood windows offer unparalleled beauty but require regular upkeep. Glass Options Both brands offer high-performance Low-E coated insulating glass with argon gas fill. However, Andersen windows can be upgraded with more advanced glazings like SmartSun glass for ultimate UV protection and efficiency. Weatherization Interstate windows are decently weather-resistant thanks to multi-chambered frames, quality weatherstripping, and insulating glass. But Andersen engineering gives their products the edge for air-tight performance and structural integrity. Window Operation Vinyl Interstate windows are lightweight and easy to operate. Andersen windows have beefier construction so the sashes may be heavier, but engineering makes them open and close smoothly. Aesthetics Interstate windows look nice and blend in well with most homes. Andersen offers far more interior wood trim and exterior color options for a more customized, upscale look. Price There's no contest here - Interstate windows are much more budget-friendly than Andersen. Even entry-level Andersen 100 Series windows cost significantly more than most Interstate models. Availability While Andersen windows can be purchased nationwide, Interstate has limited distribution focused in the Midwestern region. This makes them far more accessible for local home improvement projects. Warranties Interstate provides a solid transferable Limited Lifetime Warranty on most vinyl windows. Andersen warranties range from 10 years to 20 years (even longer on some parts) giving their products an edge here. So in summary, the major differences come down to construction materials, glass technology, overall performance, aesthetics, cost, and warranty coverage. Andersen is the leader in many respects, while Interstate offers a more affordable vinyl alternative. Also Read: Differences Between Relief Windows And Window World. Interstate Or Andersen Window Lines Head-to-Head Comparisons Now let's see how specific Interstate series stack up against comparable Andersen window collections: Interstate Essential Series vs. Andersen 100 Series The Essential Series is Interstate's most affordable vinyl window line while the 100 Series represents Andersen's low-cost vinyl windows. While both window lines utilize quality vinyl frames, the 100 Series offers thicker walls and stronger fusion welded corners. The Essential Series has basic insulating glass while the 100 Series can be upgraded to High-Performance Low-E4® glass for better efficiency. Both come with grilles, screens, and hardware options to choose from. Overall, the Andersen 100 Series provides better construction, weatherproofing, and glass but costs about 2-3 times as much as the Interstate Essential Series. Interstate Premium Series vs. Andersen 200 Series Moving up a step, the Premium Series is Interstate's mid-range window while the 200 Series signifies Andersen's mid-level Fibrex windows. The Premium Series has sturdier vinyl frames, increased insulation, and Cardinal LoE3-366 glass. The 200 Series gives you composite strength and Low-E4® SmartSun glass. Both offer good performance, numerous style choices, and customizable options. The Andersen 200 Series with Fibrex composite frame and advanced glass technology provides superior quality and durability. But the Interstate Premium Series makes for an impressive, more affordable alternative. Interstate Select Series vs. Andersen 400 Series Finally, we have Interstate's top-of-the-line Select Series versus Andersen's premium 400 Series Fibrex windows. The Select Series gets upgraded vinyl, weatherstripping, hardware, and the best Interstate glass package. The 400 Series is as good as windows get with heavyweight construction, virtually indestructible Fibrex frames, advanced Low-E4® glass, and unparalleled weather-tight performance. There's no comparison here - the Andersen 400 Series is head and shoulders above the Interstate Select Series in every way. But be prepared to pay for the quality as Andersen 400 Series windows cost 5-10 times more! Also Read: Differences Between Window Mart And Pella Windows. Key Considerations When Choosing Windows Now that you see how Interstate and Andersen windows stack up, here are a few pointers for selecting the right brand and models for your home: Climate - Consider glass capabilities, structural integrity, and materials best suited for weather and temperatures in your region. Vulnerable areas need Andersen's best weatherization features. Home Style - Pick windows that complement your home's look and size appropriately. Andersen offers more stylistic options for cottages and historical homes. Budget - Andersen windows command premium pricing starting around $600 up to $2,000+ per window! Interstate keeps you under $300 per window installed. Efficiency Needs - Old drafty homes benefit most from Andersen window technology while newer construction may get ample comfort and savings from Interstate. Installation - Hiring a professional is best for either brand. Self-installing Andersen windows risks compromising their warranties. Warranty - If you plan to stay in the home long-term, splurge for Andersen's 20-year coverage rather than Interstate's lifetime limited warranty. Which is Better for Your Home? When making your final window selection between Andersen and Interstate, consider what factors mean the most for your situation. Those wanting the absolute best in every category should go with Andersen windows. You'll pay dearly, but their performance and quality are unmatched. Andersen is the choice for homes needing uncompromising weatherization and efficiency. Their windows can even add resale value. Homeowners on a tight budget who still want quality replacement windows can feel confident with Interstate. Offering competitive durability, energy savings, and attractive style at accessible price points, Interstate presents the better overall value. They make a great choice if your home's needs are relatively basic. Ultimately, conducting your own thorough evaluation is advisable before investing in new windows. Carefully examine what performance specs, features, and costs matter for your home. This helps determine if premium Andersen windows are worth the splurge or if budget-friendly Interstate models make more sense. Once you make your brand selection, work with an experienced local window professional to ensure proper installation for long-lasting enjoyment.
