DIY Van Window Trim

Transforming a standard van into a cozy and functional campervan involves paying attention to even the smallest details, such as the window trim. Properly installing and styling window trims can add a touch of sophistication to your van's interior and exterior, giving it a modern and polished look. In this blog, we will guide you through the process of DIY van window trim, exploring various styles and materials to help you achieve your dream campervan interior.


Understanding Interior and Exterior Window Trim

Before diving into the DIY process, it's crucial to grasp the difference between interior and exterior window trim. Interior window trim refers to the decorative molding placed around the inside of the window frame, enhancing the aesthetics of your van's interior. On the other hand, exterior window trim is installed around the outside of the window frame, providing protection and sealing against the elements.


How to Install Interior Window Trim

Installing interior window trim is a relatively straightforward DIY project that can significantly impact your van's overall appearance. To get started, you'll need an interior window trim kit, which often includes pre-cut pieces for easy installation. Follow these general steps to install your interior window trim:

  1. Place the window trim around the AMA window sill inside the van.
  2. Apply self-tapping screws or riv-nuts to secure the trim around the window frame. This flange should be on plane with the factory walls of the van.
  3. Sand, paint, or upholster the trim to match your campervan's interior decor.


Exploring Modern Interior Window Trim Styles

Modern window trim styles can add a contemporary touch to your van's interior. Consider these popular options:

  1. Simple and Sleek: Opt for clean lines and minimalist designs to achieve a sleek and modern look.

Enhancing the Exterior with PVC Window Trim

PVC exterior window trim is an excellent choice for your campervan due to its durability and resistance to harsh weather conditions. Follow these steps to install PVC trim around your van's exterior windows:
