FOLZEN KOREA’s bottom rail smart cover protects the lower rail from external impact and debris,
improving durability and enhancing the overall finish of the folding door system.
When the door is closed, the smart cover seals the bottom gap,
improving airtightness and helping block wind and rain to maintain a more comfortable indoor environment.
3. Industry-Leading Thermal Insulation Test Report


Folding doors feature large openable areas, making thermal insulation performance a critical factor.
FOLZEN KOREA holds certified thermal insulation test reports verified through testing on various glass specifications.
This helps improve building energy efficiency, reduce the impact of external conditions, and maintain a comfortable indoor environment.
4. Wind Load Test: Achieved Class 160 and Class 200


Folding doors are installed in wide opening spaces, making wind resistance an important factor for stability.
In particular, environments exposed to strong winds, such as coastal areas or high-rise buildings,
require reliable wind pressure performance as it is directly related to product safety.
FOLZEN KOREA has achieved Class 160 for its 70mm thermal insulated folding door
and Class 200 for its 90mm thermal insulated folding door through wind load testing.
With a robust frame structure and precision hardware system,
the products are designed to ensure stable and reliable performance even under strong wind conditions.
