TheTerraNova® advanced High‑Pressure Silicone Coating System(HPS Si/Si) ‑ a dual‑sided silicone application that encases every yarn in a high‑performance protective layer. By coating both sides of the groundsheet textile, this system delivers exceptional water resistance, eliminates the need for conventional WR treatments, and is fully C0 by design. The mirrored silicone layers also work in harmony, creating a symbiotic partnership that enhances stability and strength exactly where the fabric is most stressed, resulting in a cleaner, lighter and more durable groundsheet than traditional alternatives
