The DelPro Xtend Jamb Extension offers a sophisticated and premium solution for enhancing the aesthetic appeal of your window jambs while streamlining the installation process.  Unlike traditional MDF jambs, which are susceptible to moisture damage and deterioration over time, the DelPro Xtend is crafted from high-quality PVC, ensuring it remains resistant to rot and requires minimal maintenace.

With three distinct options and an adaptable trim, this innovative product allows for exceptional customization, enabling it to fit seamlessly into any window jamb configuration.  Its straightforward installation process makes the DelPro Xtend an ideal choice for a wide range of window applications, marrying functionality with elegance for a beautiful finish that will last.

What is a PVC Window Jamb Extension?

The DelPro Xtend PVC window jamb extension is a high-quality solution designed to improve the appearance, functionality, and durability of window frames. Acting as a trim piece, DelPro Xtend extends the inside edge of a window frame to sit flush with the interior wall, covering gaps and creating a seamless, polished look that complements any room.

Key Features and Benefits of DelPro Xtend:

  • Enhanced Aesthetic Appeal: DelPro Xtend covers the rough openings of windows, providing a professionally finished look to interior frames. It creates a clean, seamless appearance, enhancing the overall style of the room and making the window look perfectly fitted to the wall.

  • Durable PVC Material: Made from durable, high-quality PVC, DelPro Xtend resists rot, mildew, and moisture, making it ideal for areas with high humidity or condensation, such as bathrooms and kitchens. This robust material provides long-lasting reliability with minimal maintenance.

  • Improved Insulation: By filling the gap between the window frame and the wall, DelPro Xtend enhances insulation around the window. This helps reduce drafts, improves energy efficiency, and supports a more comfortable indoor environment.

  • Versatile Application: DelPro Xtend is suitable for both new construction and retrofit projects, making it an adaptable choice for various project needs. Its versatility allows it to work well in both residential and commercial settings, ensuring a professional finish in any space.

  • Optional Adaptor Trim for Easy Installation: To simplify installation and ensure a seamless fit, an optional adaptor trim is available. This adaptor trim connects the jamb extension securely to the existing window frame, making installation quick and straightforward while providing a precise, custom fit.
