  • 95% Opening Width: Fold the panels away to fully merge your living room with the garden or terrace, creating a true open-concept space.

🛡️ Engineered for North American Climates 

  • NAFS DP50+ Rated: Built to withstand the rigorous air, water, and structural requirements of the USA and Canada building codes.

  • Advanced Thermal Break: Equipped with 24mm-32mm PA66 nylon thermal strips to prevent heat loss in winter and keep interiors cool in summer.

  • Energy Star Compliance: Combined with Low-E coating and Argon gas, our doors help significantly reduce HVAC energy costs.
