PVC Trim Boards

PVC trim boards deliver crisp, long-lasting finishes for exterior and interior projects without the headaches of wood. Made from cellular polyvinyl chloride, they won’t rot, absorb moisture, or invite insects, and they resist splitting, cupping, and warping across seasons. That means cleaner lines, fewer callbacks, and low maintenance for years.

Use them for fascia, rakes, frieze and water tables, window and door casings, corner boards, skirting, and porch wraps; they also shine in wet interiors like baths, laundry rooms, and basements.

Most boards come factory white with smooth or woodgrain faces, squared or eased edges, and in common thicknesses (5/8, 3/4, 1, 1-1/4 inch) and lengths up to 18–20 feet. Sheets and decorative mouldings round out the lineup, letting you match profiles across an entire build.

Installation is straightforward with standard woodworking tools: cut, route, and sand like pine while enjoying cleaner edges. Fasten with stainless or coated screws/nails; for best results, use hidden fastening systems or plug kits. Bond joints with PVC cement or two-part adhesives, and seal scarf joints. Allow for thermal movement—leave small gaps at butt joints, glue and clamp long seams, and paint darker colors only with high-quality 100% acrylic latex formulated for vinyl; check manufacturer LRV limits.

Pro tips:
- Pre-drill near ends to avoid mushrooming.
- Wipe cut edges to remove static dust before painting.
- Store flat, supported, and out of direct sun prior to install.
- Do not use as a structural member or for high-heat surfaces.

Benefits you’ll notice: faster installs, consistent dimensions, lighter weight than many hardwoods, and a finish that stays bright without periodic scraping or replacement. While unit cost can exceed primed wood, total ownership typically drops thanks to durability and reduced repaint cycles.
