Jointex

Jointex is a durable expansion joint filler made from closed-cell polyethylene foam. Joluka manufactures it to meet the needs of modern construction projects. The foam resists water, chemicals, and rot, making it ideal for concrete and masonry joints. It compresses easily and recovers its shape, ensuring long-term performance in both static and dynamic applications. The product arrives pre-cut to size, which saves time and reduces waste on site. It includes a removable insert that creates a clean groove for sealant application. This feature helps achieve a neat finish and improves joint sealing. Jointex bends easily, allowing it to fit curves and corners without difficulty. Its flexibility makes it suitable for complex layouts and varied construction environments. Jointex also provides thermal and acoustic insulation. It has low thermal conductivity and naturally dampens sound, adding value to residential, commercial, and industrial builds. The material performs well in extreme temperatures, ranging from -40°C to +90°C. It does not require a bond breaker, which simplifies installation and reduces costs. Safety is another key benefit. Jointex is non-toxic and safe to use. Even when burned, it releases mostly carbon dioxide and water vapour, with minimal harmful emissions. The product is available in various sizes and can be supplied in rolls or sheets. Builders choose Jointex for its strength, flexibility, and ease of use across a wide range of construction applications.
