Hello~

Folzen Korea’s 90mm System Door (24T) has successfully demonstrated enhanced performance through official certified testing

and has received the official test report.

The product achieved a U-value of 1.196 W/㎡·K,

and by applying 24T single-sided low-E double glazing,

it attained Class 1 airtightness in the Energy Efficiency Materials Test.

These results confirm that the system door not only provides excellent thermal insulation

but also effectively blocks external air infiltration,

ensuring superior airtight performance.

These results reflect the continuous efforts of Folzen Korea in technological development and quality management,

once again demonstrating the competitiveness of our products.

Moving forward, Folzen Korea will continue its research and development,

delivering even more reliable products and highly refined premium solutions.

Thank you.
