SPC wall panels, thanks to their excellent performance, are widely used in bathroom paneling. Their most important function is waterproofing, which is also the key advantage that distinguishes them from other materials.

In structural design, the locking system is especially critical. It not only directly affects waterproof performance but also determines installation convenience and user experience, making it one of the most important factors in evaluating the quality of SPC wall panels.

Common Locking Systems

Unilin

The Unilin locking system originated from Unilin Technologies in Belgium, one of the earliest companies to develop patented locking systems. Its common type is the angle-angle lock, a classic and mature structure with high stability. Known for its tight joints and wide application, Unilin technology is widely used in flooring and SPC wall panels, making it a benchmark solution in the industry.

Valinge

The Valinge locking system comes from Välinge Innovation in Sweden, a pioneer in flooring locking technologies. Its representative designs include angle-drop and the 5G single-direction lock, both known for their easy and quick installation. With efficient assembly and disassembly, Valinge locking systems are suitable for projects requiring fast installation and have also been increasingly applied to SPC wall panels.

i4F

The i4F locking system, developed by Innovations4Flooring (i4F), is a new-generation technology that has grown rapidly in recent years. It offers a variety of designs, including single-direction locks and hybrid locking structures, providing a balance between waterproofing and installation convenience. As demand continues to grow, i4F locking systems have become increasingly popular in SPC wall panel applications.

Trioflor’s Innovation and Improvement

Trioflor has optimized and upgraded the i4F locking system to better suit the application needs of SPC wall panels. The improved system demonstrates stronger waterproof performance, fully meeting the requirements of high-humidity environments such as bathrooms.

At the same time, installation convenience has been enhanced, significantly improving construction efficiency. In addition, cost optimization makes the solution more competitive. With a panel thickness of 3.7mm, the design ensures stability and offers excellent market adaptability.

Conclusion

The locking system design of SPC wall panels must strike a balance among waterproofing, installation convenience, and cost. Trioflor’s modified i4F locking system, validated through years of market use, not only delivers excellent performance but also achieves better cost efficiency.

Overall, the i4F locking system is the best choice, and Trioflor’s solution provides the most competitive value for SPC wall panels.
