Replacement Windows vs Insulation: Do You Need Windows or Insulation First?

When your home starts to feel way too cold in the winter or suffocatingly hot in the summer, your windows are probably one of the first things you’ll think to blame. But while it’s true that old, single-pane windows can contribute to poor energy efficiency, they are usually not the biggest source of energy waste, and replacing windows is often an expensive last resort when it comes to improving energy efficiency.  

Air sealing and insulation have a much greater impact on your home’s performance and are the first and most important steps toward a more comfortable, energy-efficient home. Here’s why: 

Air Sealing and Insulation Offer More Benefits 

Your home loses much more energy through the walls, attic, and basement than it does through the windows. Just think about how much more surface area your walls take up than your windows do—if they’re full of air leaks or don’t have enough insulation, you’re sure to feel the effects. By sealing air leaks and upgrading damaged or insufficient attic insulation, basement insulation, and wall insulation you’ll see benefits including: 

  • Greater home comfort 

  • Lower energy bills 

  • Better indoor air quality

  • Less noise infiltration 

Air Sealing and Insulation Cost Less than New Windows 

Having all new windows installed is extremely expensive. Air sealing and insulation are much more affordable, helping you save money upfront, and they’ll provide a greater return on your investment, saving you money in the long run, too. 

Air Sealing Can Make Your Windows More Efficient 

Window contractors may want you to think otherwise, but you can often improve your windows’ efficiency without replacing them. By sealing up gaps and cracks around your windows you can make them more efficient for a fraction of the cost of a replacement.
