Typically, exterior door jambs are made from two primary materials due to their weather-resistant properties and ability to withstand constant wear and tear:

Vinyl

Vinyl exterior door jambs are a popular choice due to their durability, affordability, and low-maintenance characteristics. Vinyl is resistant to rot, warping, and fading, making it an excellent choice for areas with fluctuating temperatures and humidity. Moreover, vinyl requires no painting or staining, saving you time and effort in maintenance.

Vinyl door jambs come in various colors and styles, allowing you to match them with your home's exterior design seamlessly. They are also lightweight, making them easy to install and handle during repairs or replacement.

Aluminum

Aluminum is another prevalent material used in exterior door jambs, renowned for its exceptional strength-to-weight ratio, durability, and corrosion resistance. Aluminum is an outstanding choice in regions with frequent rainfall or high humidity, as it does not rust or rot like steel or wood.

Aluminum door jambs often come pre-painted or anodized, ensuring long-lasting color and minimal maintenance. However, they can be more costly than vinyl and require professional installation to ensure a proper seal and prevent water penetration.
