When it comes to shopping for replacement windows in Northbrook, IL homeowners are mostly interested in one thing. They want to know which windows are going to be the most energy efficient.

Here is what you should know:  

replacement windows in Northbrook, ILFrame Material  

There are four main materials on the market: vinyl, aluminum, wood, and fiberglass.  

  • Vinyl windows. These are affordable, versatile, low maintenance, and highly efficient. That said, these windows do not last as long as some of the other window materials.  
  • Aluminum windows. These products are light, strong, durable, and a good mid-level product. And while the material itself isn’t energy efficient manufactures use thermal breaks and foam insulation to reduce heat transfer.  
  • Wood, or wood clad windows. These windows are elegant, traditional, and still a popular choice for many homeowners. They are natural insulators but do tend to require more work when it comes to maintenance.
  • Fiberglass windows. Many consider these the best products the market has to offer. They are strong, lightweight, long lasting, and energy efficient. You probably pay top dollar but the value speaks for itself.  

Window Style 

After frame material, you need to think about the window style. This dictates how the window will look and function.  

  • Picture windows. When it comes to efficiency, picture windows are usually at the top of the list. These windows do not open or close. There are no breaks in the assembly. As such, these windows are airtight and less likely to have air leaks.  
  • Casement and awning windows. Casement windows hinge to one side and swing out to open. Awning windows are similar, but hinge at the top and push out. The reason these windows are so energy efficient is that they can close and latch tight. And if the wind blows against the window it helps to tighten the seal.  
  • Sliding, single hung, and double hung windows. Sliding windows move horizontally to open and close. Single hung windows have one pane that moves up and down over a fixed sash. Double hung windows feature two moveable panes that slide up and down. These windows have multiple breaks in the assembly and are not as airtight or efficient as other styles.  

Glazing Technology 

Last but not least, the type of glass you choose and glazing technologies do a lot to contribute to the energy efficiency of windows. The current standard is two panes of glass with a space between sealed as a single unit called an IGU. You can choose different types of inert gas to go between the panes as well as special tints, laminates, and coatings. To get help choosing the right glazing technologies for your home, you should sit down and consult with a professional.
