What to Really Look For in a Replacement Window

Searching for the best replacement windows? If you ask five different window replacement professionals what’s the most important thing to look for in a replacement window, you’ll likely get five different answers. If you asked me, I’d tell you what you should really be looking for in a replacement window are three key elements: air infiltration rating, design pressure and of course, aesthetic appeal. But that’s just scraping the surface. Let’s get into everything you (actually) should be looking for in replacement windows. 

Summary 


What to look for when buying replacement windows (ranked from most important to least important).

  1. Air infiltration rating
  2. Design pressure
  3. Glass options 
  4. Frame material (vinyl, wood, fiberglass) 
  5. Color & style (hung, bay/bow, sliding) 
  6. Cost

Window Replacement Buying Considerations

Choosing replacement windows can feel overwhelming but breaking it down into what matters most can help. Here’s a simple guide to help you prioritize the key factors, from the most important to the least (but just remember they’re all important). 

Air Infiltration Rating

Why it’s important: This rating tells you how much air can sneak through the window when it’s closed. A lower air infiltration rating means fewer drafts and better energy efficiency. Simply put, it helps keep your home cozy and your energy bills lower. A lower air infiltration rating means having fewer chilly drafts in the winter and less hot air seeping in during the summer – that's what a good air infiltration rating can do for you.

Design Pressure

Why it’s important: Design pressure (DP) measures how well a window can handle strong winds and heavy rain. A higher DP rating means your windows are tougher and more durable. If you live in an area with harsh weather, this is super important. You want windows that can stand up to the elements and keep your home safe and dry.

Glass Options

Why it’s important: The type of glass affects how well your windows insulate your home. Here are some options:

  • Low-E Glass: Reflects heat to keep your home warmer in winter and cooler in summer.
  • Double or Triple Glazing: More panes mean better insulation.
  • Tempered and Laminated Glass: Adds safety and reduces noise. Choosing the right glass can help you save on energy bills, reduce outside noise, and add an extra layer of safety.

Frame Material 

Why it’s important: The frame material affects how long your windows last and how much maintenance they need. Here’s a quick rundown:

  • Vinyl: Affordable, low maintenance, and energy efficient.
  • Wood: Classic look, great insulation, but needs regular upkeep.
  • Fiberglass: Very durable and low maintenance. 

Picking the right frame material ensures your windows look good, last long, and help keep your home energy efficient.

Color & Style 

Why it’s important: The color and style of your windows affect your home’s look, but also its functionality. You want to choose a design that complements your home’s exterior and boosts your curb appeal. Here are some popular window styles:

    • Double-Hung: Both sashes move, making them easy to clean and versatile.
    • Bay/Bow: These project outward, adding space and a great view.
    • Sliding: Slide sideways and are great for wide openings.
  • Picture window: A single pane window that frames a view outside (like a picture) and does not open.

Cost

Why it’s important: While it’s important to stick to your budget, remember that cheaper windows might not save you money in the long run. Investing in high-quality, energy-efficient windows can lower your energy bills and add value to your home. Get several quotes, consider the long-term savings, not just a quick and cheap upgrade that won’t last more than a few years.

Window Replacement FAQs

What is the most cost-effective window replacement?

 

Vinyl windows are often the best bang for your buck. They’re affordable, durable, and energy efficient. Standard styles like double-hung or sliding windows are usually cheaper than custom or specialty windows. Also, look for local rebates or government incentives for energy-efficient windows – these can help you save even more.

 

How do I choose a new window?

 

Start by figuring out what you need – are you looking for better insulation, noise reduction, or a new look? Then, research different materials like vinyl, wood, and fiberglass. Check for ENERGY STAR ratings to ensure energy efficiency. Think about the style that will look best with your home – double-hung, casement, or sliding windows are popular choices. Finally, read reviews and get quotes from several suppliers and installers to find the best deal.

 

Is it worth it to buy expensive windows?

 

Yes, expensive windows can be worth it! They usually offer better energy efficiency, which can lower your heating and cooling bills. They’re often more durable, so you won’t need to replace them as often. Plus, they usually come with better warranties. High-quality windows also make your home more comfortable and can boost its value.
