Insulated glass units, often called IGUs, help homes feel comfortable through Kansas City’s hot summers and cold snaps. These multi-pane assemblies reduce heat loss, manage solar gain, and support indoor comfort without changing the look of your windows. At Westport Glass & Mirror, we craft custom insulated glass to improve your home’s energy efficiency while maintaining a clean, modern look.




Most IGUs last between 10 and 20 years, depending on installation quality, weather exposure, and seal integrity. Temperature swings and humidity in the Kansas City area can shorten lifespan, making timely replacement important once seals fail.

Most insulated glass unit replacements can be completed in a single visit once the custom glass is fabricated. Installation is efficient and minimally disruptive, making it an ideal upgrade for both residential and commercial customers.
This is the BEST place to obtain custom cut glass and mirrors. Whether it is glass shelving, glass for cabinet doors, mirrors or repairs, you just can't beat this place. Very reliable, VERY careful about measurements and getting it right the first time, and great prices for the high level of service. I have done business with Westport Glass since they were actually IN Westport. It's a GREAT company!
Punctual with pickup and delivery. It was only a one hour window and they did what they said they would do. Excellent customer service. Gave me options on replacement glass for console table. They were knowledgeable about their product and did a beautiful job. So refreshing to have a company with customer service. I will definitely use them again and highly recommend this local company. They also did a new shower door for me years ago - once again, I was thrilled with the door and their service. Go Local and use Westport Glass when you have the opportunity!
We had a great experience with Westport Glass. The staff was friendly and informative. We are more than happy with the shower doors they installed! We appreciated their honesty that what I wanted wouldn't work and why it wouldn't work. The installers were friendly and fast. I would recommend Westport Glass to anyone needed shower doors or enclosure. Love that it is a FAMILY run company!
