Hello.

Today is the news of obtaining a test report.


Folzen Korea's 90mm system door .(24T one-sided, multi-layered glass)


In the efficiency management equipment test, the airtightness level 1 and the heat perfusion rate 1.281.


It has been recognized for its best insulation and airtightness!!

The 90mm system door of Folzen Korea has a thermal conductivity that is transmitted through the material per unit area.


It recorded 1.281 and achieved a high level of confidentiality level 1.


In the case of insulation, the closer the heat flow rate is to zero, the better it is,


The lower the heat flow rate, the more it prevents heat from entering the outside and inside.


It is excellent for keeping the indoor temperature comfortable in summer and winter.

Folzen Korea's system door has excellent airtightness and prevents air from passing through it.


It also received the highest grade 1 for confidentiality testing.


Airtightness greatly helps with windproof and soundproofing.



Folzen Korea will not be satisfied with the present and will study more.


We will develop a folding door with the best technology.



Thank you.
