The most economical BIPV system on the market, the GSE IN-ROOF SYSTEM is the most competitive and certified building integrated solution for residential new builds.

Reliable and resistant

  • The GSE IN-ROOF SYSTEM has been designed to offer the same resistance and longevity as normal roof coverings like tiles, slates or zinc.
  • Very important mechanical resistance, compatible with all snow and wind zones:
    – Downward pressure: 5400 Pa (IEC 61215)
    – Upward pressure: up to 5500 Pa (NF EN 12179)

    Eurocode design values: Snow: 1800 Pa, Wind: 1700 Pa
  • Impact resistance: the quality of the polypropylene used in the French manufacturing plants and the multiple tests at the CSTB have proven the durability of the system.
  • GSE Intégration benefits from the know-how of its parent company TERREAL which consolidates over 150 years of experience and expertise in the manufacture of tiles.

Operational advantages when fitting

  • With no risk of error, the patented system is assembled by interlocking the various parts, which fit together precisely without cutting or joining
  • Quick to use: 8- to 16-module system installed in a day
  • Lightweight (2,5 to 3,5 kg/m²) and easy to transport
  • Flexible, adapts to all roofing configurations
    • The system may be installed in portrait or landscape format.
    • All types of desired configuration (U-shaped, pyramid, etc.)
