In Summer,there is always typhoon from sea,it will bring big wind and raining to coastal region.We also often hear from news that rock wool insulation of some buildings fall off during windy.It’s very dangerous to humans and also make financial loss to resident.So How to protect rock wool insulation against falling off in coastal region?
（1）It’s important to choose suitable and good rock wool board.The main property is density,hydrophobicity and vertical intensity.The density will affect the weight of insulation.Raining is always coming with wind.so hydrophobicity is also very important to against falling off.
Vertical intensity is more direct element to bear wind pressure.
（2）the bond of insulation layer
It’s necessary to use mortar and gridding cloth special for rock wool,the coating area and thickness must be enough.
（3）the anchoring of insulation is more important element to protect insulation layer.
This requirement containers two parts – thermal insulation fasten nail and bricks.
The strength and quantity of fasten nail must meet design requirements.The bricks also very important.The nails are anchored to bricks,the strength of bricks also must be high enough.
