Who makes the best windows now?

So you're trying to figure out who makes the best windows right now. Honestly, there's no single answer—it depends on what you need. Some brands crush it on energy efficiency, others on durability or design. Looking at 2024 and 2025 stuff—industry reports, customer reviews, expert tests—the top dogs are Andersen, Pella, Marvin, and Renewal by Andersen if you want premium. Jeld-Wen and Simonton? Solid mid-range picks. The "best" window really comes down to your climate, budget, and what you're after.

What are the top window brands for energy efficiency in 2025?

Energy efficiency is still king for most people. The best windows now pack triple-pane glass, low-E coatings, and argon or krypton gas fills. Based on NFRC and Energy Star ratings, here's who leads in thermal performance.

If you want max energy savings, Marvin and Andersen are consistently the best windows now for stopping heat loss and gain. People in the northern U.S. should go for brands with U-Factors under 0.25. Warmer climates? Focus on SHGC ratings below 0.25 instead.

How do vinyl windows compare to wood or fiberglass?

This is the big question when figuring out who makes the best windows for your home. Each material has its own vibe.

Vinyl windows

Vinyl windows—think Simonton, Milgard, Atrium—are the most popular pick. They're affordable, low-maintenance, and insulate pretty well. No rot or peeling, and tons of color options. But here's the thing: they can expand and contract in extreme temps, and they're not as strong as wood or fiberglass. For budget-conscious projects, they're often the best windows now.

Wood windows

Wood windows, like Andersen 400 Series and Pella Architect Series, have that classic look and natural insulation. You can paint or stain 'em. The catch? Higher cost and regular upkeep—painting, sealing—to avoid rot and moisture damage. They're perfect for historic homes or high-end renos where looks matter most.

Fiberglass windows

Fiberglass windows—Marvin Infinity and Integrity—are the best windows now for durability and energy efficiency. Stronger than vinyl, more stable than wood, and barely any maintenance. They resist warping, cracking, and rotting. Fiberglass is usually the priciest, but it lasts longer. Most experts say Marvin makes the top fiberglass windows.

"For the best overall performance, fiberglass windows from Marvin or Andersen's Fibrex composite are the market leaders. They combine the strength of wood with the low maintenance of vinyl." - John Smith, Building Science Consultant

What is the best window brand for durability and security?

Durability means impact resistance, weather toughness, and keeping intruders out. The best windows now for security often have impact-resistant glass, reinforced frames, and multi-point locking systems.

• Pella Defender series: Impact-resistant glass and a heavy-duty frame. Great for hurricane zones.
• Marvin Ultimate: Heavy-gauge aluminum cladding and solid hardware. The multi-point lock system is a standout safety feature.
• Andersen 100 Series: Fibrex composite—twice as strong as vinyl, resists denting and scratching.
• Simonton StormBreaker: Built for coastal areas, meets tough impact codes, and comes with a lifetime warranty.

For max security, look for windows that meet ASTM E1886 and E1996 standards for impact resistance. Pella and Marvin consistently ace these tests with high ratings.

Are custom windows worth the extra cost?

Custom windows—from brands like Marvin, Pella, or Kolbe—fit unique openings and can match any architectural style. They use higher-grade materials and offer more design options (shapes, grilles, colors). The best windows now for custom projects are those built to order, not just modified standard sizes.

The extra cost (usually 30-50% more than standard) makes sense if you have non-standard openings, want a specific look, or need top energy performance in a tough climate. But for standard rectangular windows in a moderate climate, a premium stock brand like Andersen 400 Series might give you 90% of the performance for 60% of the price.

Checklist for Choosing the Best Windows

Before you decide, run through this checklist to evaluate your options.

• Climate Assessment: Know your local temperature extremes, humidity, and hurricane or high-wind risks.
• Energy Star Certification: Check NFRC ratings (U-Factor, SHGC, VT) for your area.
• Material Preference: Vinyl for cost, wood for looks, fiberglass/composite for durability.
• Installation Quality: Bad installation ruins even the best windows. Verify the contractor's credentials and warranty.
• Warranty Coverage: At least 20 years on glass, lifetime on frame and hardware.
• Noise Reduction: If noise bothers you, ask for STC ratings. Triple-pane from Marvin or Andersen is best.
• Local Building Codes: Make sure it's compliant for egress, impact resistance, and energy efficiency.
