What is plastic windows called?

Plastic windows, also known as PVC windows or vinyl windows, are a popular choice for homeowners and businesses alike due to their durability and energy efficiency. These windows are made from a type of plastic called polyvinyl chloride (PVC), which is a lightweight, versatile and easy-to-manufacture material. In this article, we will explore the benefits of plastic windows, their construction, and the various types of PVC windows that are available.

Benefits of Plastic Windows

One of the main advantages of plastic windows is their energy efficiency. These windows are made of a multi-chambered design that acts as an insulator, preventing unwanted heat transfer from inside to outside. This means that in the winter, plastic windows can help keep your home warm and cozy, while in the summer, they can prevent unwanted heat from entering your home. Furthermore, their energy-saving properties can help reduce energy bills, making them a wise investment in the long run.

Another major benefit of plastic windows is their durability. Unlike wood or aluminum windows, PVC windows are resistant to warping, cracking, and rotting, meaning they can last for many years without needing to be replaced. They are also easy to clean and maintain, as they require no special treatments or coatings like wooden windows.

Construction of PVC Windows

Plastic windows are constructed from a number of components that work together to form a sturdy and efficient window. The key parts of a PVC window include:

- Frame: The main structure of the window, which is constructed from PVC material and has multiple chambers to enhance insulation.

- Glass: The transparent part of the window that allows light and views into the room. PVC windows can come in single, double, or triple-pane options, with the latter providing the best insulation.

- Sash: The part of the window that holds the glass in place and can be opened or closed. PVC window sashes can be designed in various shapes and sizes to suit specific needs and preferences.

- Hardware: The mechanisms that allow the window to be opened or closed, including handles, locks, hinges, and cranks.

Types of PVC Windows

There are several types of PVC windows available on the market, each with its own unique features and benefits. Let's explore some of the most popular types of PVC windows:

- Casement Windows: These are windows that are hinged on one side and open outwards, like a door. Casement windows provide excellent ventilation and can be designed in various shapes and sizes, including single or double sash variations.

- Sliding Windows: These are windows that slide horizontally on a track, providing easy and convenient operation. Sliding windows are ideal for wider openings and can come in various configurations, including single and double sliders.

- Awning Windows: These windows are hinged at the top and open outwards from the bottom. Awning windows provide good ventilation and are ideal for basements and bathrooms where privacy is a concern.

- Bay and Bow Windows: These are complex windows that are made up of multiple panes and angles, creating a protruding space from the exterior of the building. Bay and bow windows provide ample natural light and a panoramic view, making them a popular choice for living rooms and bedrooms.


In conclusion, plastic windows, also known as PVC windows or vinyl windows, are a great way to improve the energy efficiency and durability of your home or business. They are made from a lightweight and versatile plastic material known as polyvinyl chloride (PVC), which provides excellent insulation and resistance to the elements. Whether you choose casement, sliding, awning, or bay and bow windows, you can be sure that you are making a wise investment in your property that will provide benefits for many years to come.
