S4 Large horizontal extension

S4 is a specialist manufacturer of in-roof solar mounting systems, designed to deliver long-term performance, flexibility, and reliability for solar PV installations. Developed to adapt to changing panel sizes and layouts, S4 systems provide full compatibility across different panel widths, heights, and orientations. With a strong focus on simplified installation, integrated waterproofing, and structural durability, S4 in-roof solutions reduce installation time while maintaining a clean, flush roof finish. Manufactured using high-quality, recyclable materials, S4 mounting systems are built to exceed 25 years of durability and are supported by a 10-year warranty, making them a future-proof choice for residential and commercial solar projects.

• Extended Lateral Coverage: Designed to elongate the horizontal support where standard S4 lateral elements do not reach, ensuring complete edge integration for wide PV arrays.
• Seamless System Integration: Fully compatible with the S4 universal in‑roof mounting system, enabling uniform mechanical and waterproof performance across the entire solar array.
• Weather‑Resistant Construction: Maintains the S4 integrated waterproofing design, preserving roof integrity without the need for additional flashings.
• Optimised Installation Workflow: Engineered for easy alignment and secure fixation within the S4 modular architecture, reducing on‑site complexity and installation time.
• High‑Quality Material Build: Constructed from durable, corrosion‑resistant materials designed to match the S4 system’s long service life and withstand exposure to demanding environmental conditions.
