PU (Polyurethane) stone panels are high-density architectural wall cladding sheets manufactured to replicate the exact texture, color, and depth of natural stone, brick, and slate without the heavy structural load.
Key Advantages
Weighing only 2–4 kg per square meter, PU panels drastically reduce wall loads and eliminate the need for structural wall reinforcements, heavy freight fees, or specialized handling equipment.
Rapid & Simple Installation:
Panels interlock seamlessly and can be mounted onto drywalls, concrete, or timber framing using structural adhesive, liquid nails, or standard stainless steel screws. They are easily cut to size using basic woodworking tools like hand saws or circular saws.
Built with high-density closed-cell polyurethane foam, these panels are completely waterproof, moisture-resistant, non-rot, and treated with UV-resistant coatings to prevent fading in outdoor environments.
Thermal & Acoustic Insulation:
The closed-cell polymer structure offers natural thermal insulation, helping stabilize interior temperatures while dampening ambient acoustic noise.
