Hello, this is Folzen Korea.

 

 

 

Folzen Korea’s 90mm System Door (32T) has officially obtained certified test reports,

 

demonstrating enhanced performance through accredited testing.

 

 

The product achieved a thermal transmittance of 1.087 W/㎡·K, and by applying 32T triple glazing,

 

it has also earned Airtightness Grade 1 in the energy efficiency equipment test.

 

 

Through these results, the product’s excellent insulation performance—effectively reducing external heat loss—


as well as its superior airtightness—preventing outside air infiltration—


have been successfully verified.

 

 

 

 

 

This achievement is the result of Folzen Korea’s continuous efforts in technological

 

development and quality improvement, and serves as another opportunity to reaffirm our product competitiveness.

 

 

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