When your project calls for extra strength and a refined finish, the ARMOR P1200 12.5mm Laminated Birch Plywood Panel delivers. This WBP-grade sheet combines a robust birch core with advanced laminate surfaces, making it a go-to choice for builders working on trailers, campervans, boats, road cases, and joinery.
Thicker Profile for Added Strength
At 12.5mm thick, this panel offers increased rigidity and load-bearing capacity compared to standard 9.5mm sheets. It’s ideal for structural flooring, cabinetry, and wall linings where durability and dimensional stability are key. The thicker profile also provides a more solid feel underfoot and better resistance to flexing in mobile environments.
Birch Core with WBP Adhesive
The panel is constructed from high-quality birch plywood, known for its strength, uniform grain, and excellent machinability. Bonded with WBP (Weather and Boil Proof) adhesive, it’s designed to resist moisture and humidity, making it suitable for semi-exposed environments like marine interiors and vehicle builds.
Black Hexagon HPL Exterior
The face side features a 1mm black high-pressure laminate (HPL) with a hexagon texture. This surface offers:
- Scratch resistance for high-traffic use
- UV protection for short-term outdoor exposure
- Moisture resistance for damp conditions
- Anti-slip grip for flooring and mobile builds
The hex pattern adds a modern, industrial look while enhancing safety in slippery or uneven environments.
PVC Laminate Backing
The reverse side is finished with a 0.35mm PVC laminate that adds moisture protection and helps maintain panel stability. It prevents swelling, warping, and delamination—especially useful in campervans, trailers, and boats where humidity and temperature changes are common.
Water Resistance for Semi-Exposed Use
While not intended for prolonged outdoor exposure, the P1200 panel can handle short-term water contact for up to 72 hours. This makes it suitable for marine cabinetry, trailer linings, and van interiors where occasional moisture is expected. For long-term outdoor use, additional sealing is recommended.
Applications That Benefit from Extra Thickness
The 12.5mm P1200 panel is ideal for:
- Trailer flooring: Stronger under load, with anti-slip surface
- Campervan cabinetry: Rigid and moisture-resistant
- Boat interiors: WBP-grade protection in humid conditions
- Joinery: A premium finish with added structural integrity
- Road cases: Durable panels for protective enclosures
Despite its thickness, the panel is easy to work with. It machines cleanly, holds fasteners securely, and responds well to both hand tools and CNC routing. Whether you’re cutting, drilling, or edge-finishing, the P900 panel maintains its integrity throughout fabrication.
The black hex ply finish isn’t just functional—it looks sharp. It’s a popular choice for builds where aesthetics matter, such as custom van interiors, display cases, and high-end joinery. The textured surface also helps conceal wear, keeping your project looking fresh over time.
