The room features a white fireplace and a large wall of windows and French doors leading to a deck, with an arched window at the top. A large, ornate chandelier hangs from the ceiling.

Quick Guide to Window Types  

3 minute read


Choosing the right windows for your home starts with understanding your options. If you’ve ever wondered. “What are the different types of windows?” and how they affect comfort, style, and energy use, you’re in the right place. This quick guide breaks down the main window types and names you’ll hear during your replacement journey, so you can make confident, informed decisions. 

Why Window Types Matter

Windows aren’t just about letting in light; they affect how your home feels, performs, and even how much energy you use. The type of window you choose influences airflow, insulation, and maintenance needs. Understanding the basics up front helps you narrow down your choices, especially when balancing appearance, function, and budget. 

Operating Window Types

Double-Hung Windows

A classic and versatile choice, double-hung windows feature two operable sashes that slide up and down. They’re great for ventilation and easy cleaning, especially models where the sashes tilt inward. 

Casement Windows

Hinged on one side and opening outward with a crank, casement windows create a tight seal when closed and catch side breezes beautifully when open. They’re ideal for areas where you want maximum airflow and energy efficiency. 

Slider (or Gliding) Windows

These windows open horizontally along a track, making them a simple, space-saving option for modern homes. They offer wide views and are easy to operate, especially in living rooms or over kitchen counters. 

Fixed and Specialty Window Types

Picture (Fixed) Windows

Picture windows don’t open, but they offer expansive, unobstructed views and excellent insulation. They’re ideal for framing scenic outdoor views or pairing with other window styles for added dimension. 

Bay and Bow Windows

Bay and bow windows project outward from the wall, creating extra space and a striking focal point. Bays typically have three panels (a large center flanked by two angled sides), while bows feature four or more panels for a gentle, curved appearance. Both styles add light, dimension, and architectural charm. 

Essential Window Terminology

Frame Materials

  • Vinyl: The most popular modern choice, vinyl frames are affordable, low maintenance, and highly energy efficient. 
  • Fiberglass: Known for strength and stability, fiberglass resists warping and performs well in extreme temperatures. 
  • Wood: Timeless and beautiful, wood offers superior insulation and a natural aesthetic but requires periodic care to prevent rot or weathering. 

Glass and Efficiency Terms

  • Insulated Glass Units (IGUs): Two or more panes separated by an air or gas-filled space that improves thermal performance. 
  • Low-E Coating: A thin metallic layer that reflects heat while allowing natural light in, keeping interiors comfortable year-round. 
  • Argon Gas: A dense, invisible gas sealed between panes to slow heat transfer and enhance insulation. 

Performance Ratings

  • U-Factor: Indicates how well a window prevents heat from escaping. Lower numbers mean better insulation. 
  • SHGC (Solar Heat Gain Coefficient): Measures how much solar heat enters through the glass, which is important for controlling indoor temperature, especially in sunny climates.

David and crew were great to work with. My install was originally scheduled for 2 days but they were able to do the whole house in one day. I love my new windows, I can already feel the difference in temperature in my house. The windows look great and were more affordable than other companies. - 4/12/2026

Can’t recommend Advanced enough. Good quality windows that are in built in house and made to last. I already can tell the difference in my energy efficiency in my home. Install was quick and clean. Highly recommend! - 4/10/2026

Had a good experience with the company, very easy and painless. Of course it was a bit pricey but they were cheaper than other companies I had looked at. Was able to get financing with 0 interest which was a huge plus. The guys who came to install were professional and were done in about 6 hours. The windows look great and are high quality. I feel like they will last a long time and will update my review over time. - 4/10/2026

Just wanted to give a big thank you to Kevin and Anthony for their time on installing new windows on our home.We have an older home that has the original windows on the home and with that can come complications upon window removals, they were efficient and effective. Extremely respectful and kind. They talked me through the steps they were taking and why. Very friendly guys who did the job in such a great way! We are so happy with our new windows, and I was amazed at how much of a difference it has made and it’s only been a few hours since they have left!From beginning to end this process has been great and we cannot wait to use them again when we end up replacing the last few windows on our home!Thank you again! - 4/10/2026

I'm very impressed with Advanced Windows! It's a company that 100% stands behind its warranty. Advanced Windows replaced all the windows in my house thirteen years ago. Since then, a few parts have worn out or needed servicing. Each time I called, Advanced Windows promptly came out and corrected the issue with a smile. Today, Gary came and replaced the latch on my sliding glass door. This company is a class act! - 4/09/2026

The men that installed our windows worked very hard. They wasted no time. They were very courteous and cleaned up after themselves. - 4/09/2026
