OPTION 1 –

Every board of XT Trim is treated with Wolman® AG, an EPA-approved, non-metallic preservative that penetrates deep into the wood fibers to resist fungi, mold, insects, and rot. Belco’s true two-step process includes a factory-applied proprietary primer on all six sides for superior moisture resistance and paint adhesion. This ensures long-term performance in diverse climates, from coastal humidity to extreme freeze/thaw conditions. Our Treatment Process In Depth

Belco XT Trim offers savings both upfront and in the long term. Because it comes preservative-treated and pre-primed, builders save labor and finishing time during installation. Its stability minimizes warping and callbacks, reducing jobsite waste and rework. Compared to cedar, redwood, fiber cement, or composites, XT Trim delivers a lower total installed cost while providing a beautiful, high-end natural wood appearance. Calculate your TRUE COSTS here!
