Plastic windows and glass windows are two popular types of windows that you can see in many houses and buildings. Among the many factors that people consider when choosing between the two, one of the most common questions is whether plastic windows are cheaper than glass windows. In this article, we’ll take a closer look at this question and see if we can answer it conclusively.

Initially, it’s important to understand that there are different types of plastic and glass windows that may have different costs, and ultimately deciding which type of windows is cheaper will depend on a number of factors, including size, materials, and installation costs. However, we’ll attempt to provide a general comparison of the two types of windows to help you make an informed decision when choosing new windows for your home.

Benefits of plastic windows

Plastic windows, also known as PVC windows or uPVC windows, are made from a type of plastic called polyvinyl chloride. They offer several benefits including energy efficiency and lower maintenance costs.

Plastic windows are very energy efficient as they are designed to provide better insulation and keep a home’s temperature regulated more effectively than glass windows. They are also more resistant to fading, discoloration, and warping over time. Additionally, PVC windows are very easy to maintain and are more affordable than wood or aluminum alternatives.

Benefits of glass windows

Glass windows are the traditional option, and come in various types including single, double, and triple-glazed windows, as well as insulated glass windows. Glass windows offer a number of benefits, including transparency, security, and durability.

Glass windows are the most transparent option, and they allow natural daylight into the house while still providing a clear view of the outdoors. They are also very durable and resistant to the elements, including wind, rain, and harsh temperatures. Additionally, glass windows can be customized to fit any style, offering many options for decorating and designing your home.

Comparing prices

When it comes to comparing prices, plastic windows are generally cheaper than glass windows, at least in terms of upfront costs. The cost of a single window unit of PVC can range from $300-$500, while the cost of a single window unit of glass can range from $500-$1000.

However, when talking about long-term costs, glass windows can be more cost-effective because of their durability and energy efficiency. Glass windows may require less maintenance and replacement over their lifetime which can ultimately save you money. It’s also worth noting that the cost of installation for both types of windows is generally similar.


In conclusion, whether plastic windows are cheaper than glass windows depends on your priorities and the specific requirements of your home. If you’re looking for affordability and low maintenance windows, then plastic windows are a great choice. If you’re looking for transparency, durability, and long-term cost-effectiveness, then glass windows are a great option to consider. Ultimately, it’s important to weigh the pros and cons of each option and choose the one that best fits your particular needs.
