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 insulated folding 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's insulation products have been recognized for their excellent performance in many tests.

In the future, 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.
