Urethane Zinc Board is a great wall and roofing material for enhancing
heat insulation, dew condensation-preventive, and noise-absorbing
performance by being filled with urethane foam.
Coating the surface of a zinc coated
alloy steel sheet, it is highly durable over time
Being filled with urethane foam which is a
construction insulator with low heat conductivity,
it shows outstanding heat insulation
performance and also saves energy
Applying urethane foam to a zinc coated alloy
steel sheet, it blocks the outside noises and
makes indoor spaces cozy and peaceful.
It is highly resistant to corrosion
and water leakage by adopting a
binding clip fixing system.
With the small effective width and thickness,
it is lightweight and therefore
applies easily in the field.
