Cork sheet is a versatile natural material, crafted from the renewable bark of the cork oak tree (*Quercus suber*). At Kaxite, we specialize in producing high-grade cork sheets that combine traditional harvesting methods with modern precision engineering. Our sheets are celebrated for their unique cellular structure, comprising millions of tiny, air-filled cells. This structure grants them exceptional properties, making them indispensable for applications ranging from industrial insulation to creative arts and crafts. Kaxite sheets are not just a material; they are a sustainable, high-performance solution for professionals and DIY enthusiasts alike.
Choosing Kaxite cork sheets means investing in a product with a superior set of inherent advantages:

What is the typical lead time for custom-sized Kaxite cork sheet orders?
For standard custom cuts, our lead time is typically 5-7 business days. For large-volume industrial orders or sheets requiring special compounding (e.g., for specific chemical resistance), the lead time may extend to 10-15 business days. We recommend contacting our sales team with your project specifications for an exact timeline.
Can Kaxite cork sheets be used as flooring underlayment?
Absolutely. Our medium to high-density cork sheets (above 200 kg/m³) in thicknesses of 6mm (1/4") or greater are an excellent choice for flooring underlayment. They provide superior sound dampening between floors, add a comfortable underfoot feel, and offer thermal insulation. Ensure the subfloor is clean, level, and dry before installation, and use a recommended flooring adhesive.
How do I clean and maintain a cork sheet surface, like a pinboard or wall panel?
For routine dusting, use a soft, dry cloth or a vacuum with a brush attachment. For light stains or spills, slightly dampen a cloth with a mild, pH-neutral soap solution, wring it out thoroughly, and wipe the area gently. Never soak cork or use harsh chemical cleaners, abrasive pads, or steam cleaners, as these can damage the natural surface. For high-traffic areas, applying a water-based cork sealer from Kaxite can provide an extra protective layer.
Are Kaxite cork sheets fire-resistant?
Natural cork is inherently slow-burning and self-extinguishing—it does not readily fuel a fire. Our premium and technical-grade sheets undergo additional treatments and testing to achieve formal fire ratings, such as Class B per ASTM E84 standards. Always check the specific product data sheet for the certified fire rating relevant to your local building codes and application requirements.
What is the best way to cut and shape cork sheets?
Kaxite cork sheets are user-friendly and can be cut with common tools. For straight cuts, a sharp utility knife, box cutter, or a table saw with a fine-toothed blade works well. For intricate shapes, a sharp craft knife, jigsaw, or laser cutter (for detailed projects) is effective. Always cut on a stable surface and wear appropriate safety gear. For a clean edge, sand lightly with fine-grit sandpaper after cutting.
Can cork sheets be used outdoors or in damp environments?
While natural cork contains suberin, which repels water, continuous exposure to standing water or extreme weather can degrade it over time. For exterior or high-moisture applications (e.g., bathroom walls, boat interiors), we highly recommend using our specially sealed or composite cork sheets. These products have enhanced water-resistant coatings or binders that significantly improve their durability in such conditions.
How does Kaxite ensure the sustainability of its cork products?
Sustainability is core to the Kaxite philosophy. We source our cork bark exclusively from certified, sustainably managed cork oak forests in the Mediterranean region, where harvesting actually promotes the health and longevity of the trees (they can live for over 200 years). Our manufacturing processes prioritize energy efficiency and waste reduction, and all by-products are recycled into other materials like cork granules or composite boards. We are committed to full traceability and ecological responsibility.
What adhesives are recommended for installing cork sheets to walls or other surfaces?
The correct adhesive is crucial for a lasting bond. For porous surfaces like drywall or plywood, a high-quality, solvent-based contact cement or a heavy-duty PVA (polyvinyl acetate) adhesive is recommended. For non-porous surfaces like metal or glass, a polyurethane-based construction adhesive or a two-part epoxy may be necessary. Always ensure both the substrate and the back of the cork sheet are clean and follow the adhesive manufacturer's instructions for application and drying times.
