ROCKWOOL CurtainRock can prevent fire from spreading to the higher floor or adjacent building unit by window or layer. The filling of CUR stone wool has an excellent performance in thermal insulation and noise reduction.
CurtainRock products are for wall between windows and windowsill wall, as a protection measure for bar structure that may be exposed to the fire at high temperature.
ROCKWOOL CurtainRock series consists of CUR110 and CUR128 whose density and strength can be customized according to the structure of curtain wall.
CUR110: Under the condition that the wall between windows has a very high strength, such as when silicate fire plates need support from keel or it is an independent window sill wall, which requires stone wool as internal filling, CUR 110 is your choice that can not only meet the requirements of fire resistance but reduce the cost as well.
CUR128：If aluminum foil sided stone wool is directly exposed to the outside, or the steel plates used are of low strength, a certain amount of pressure will deform the inside of window wall. Since the inter-layer filling would squeeze the stone wool, this structure requires CUR128 of higher strength.
