Perfect fire resistance
Glass wool panels use glass fibers which are noncombustible materials for the inside of panels and therefore have perfect flame- and fire-resistance minimizing damages of fires.
Excellent sound absorption
Glass wool panels enables excellent sound absorption and therefore appropriate for facilities such as sports complex causing a lot of noises without needs for additional soundabsorbing materials.
Excellent insulation
As glass fibers are thin and consist of uniform filaments and therefore they have lower heat conductivity with excellent insulation, thus reducing heating and cooling cost.
Enhanced durability
Surface materials with excellent strength and glass fibers with excellent restoration and tensile strength are vertically formed to have enhanced durability with excellent compression and structural strength.
DONGYANG PANEL SYSTEM
DONGYANG glass wool panels use the glass fibers which are first grade pure inorganic materials and therefore they are not burnt by fire and do not cause hazardous gases, minimizing risks by fire. In addition, excellent sound absorption of glass fibers absorbs noise inside buildings and prevents external noise, thus creating comfortable spaces.
