When it’s time to replace your windows, the number of options can feel overwhelming. You’re not just picking a product — you’re making an investment in your comfort, energy bills, and home value for decades to come.
At Windows on Washington, we’ve helped thousands of homeowners make window choices that match with their unique needs. We’ve put together a quick primer on how to ensure you pick a window that lasts a lifetime
🔍 What Makes a Window Last?
It’s not just about looks. The best replacement windows excel in three critical areas
- Energy Efficiency
- Durability & Materials
- Installation Quality
Let’s break these down.
💡 1. Energy Efficiency: Lower Bills, More Comfort
You spend a lot of money on energy bills to keep your home exactly the way you want it! The best replacement windows keep your indoor temperatures stable and your energy bills low. Look for:
- Low U-Factor: Window insulation is key to ensuring heat doesn’t get transferred. A low U-Factor ensures your home will stay warm in the winter and cool in the summer.
- Low Air Infiltration Ratings: Air leaks are one of the biggest energy wasters and not all windows are created equal. The lower the number, the less air that window lets in.
- Low-E Glass: Reflects heat back into your home in winter and blocks heat in summer.
- Argon or Krypton Gas Fills: Adds insulation between panes.
- Warm Edge Spacers: Improve thermal performance at the edge of the glass.
💬 WoW Tip: Windows on Washington choses OKNA windows because of their effectiveness across these measures; In fact the Enviro-Star 800 Series has industry-leading low air infiltration — reducing typical home energy use by up to 40%
🪵 2. Materials: Know What You’re Buying
Window frame materials and construction affect energy efficiency, appearance, and maintenance.
✔ Premium Vinyl
- Low maintenance and more affordable
- Premium brands will not discolor or warp
- More common in modern replacement projects
✔ Composite (APC)
- Looks like wood, performs like a tank
- High structural integrity and energy efficiency
✔ Wood
- Beautiful and natural
- High maintenance and susceptible to rot
- Less common in modern replacement projects
💬 WoW Tip: how windows are made will impact the durability of that window over time; premium features like magnetic seal or structural reinforcements can make the difference between something that lasts 2-3 years vs. something that lasts a lifetime
