| Note: usually, the material with low thermal conductivity is regarded as thermal insulation material (it is stipulated that all the materials with a thermal conductivity no more than 0 . 12w/(m · k) when the temperature is lower than 350ºC called thermal insulation materials in national standard .), and the material with a thermal conductivity less than 0.05w/(m ·k) is named high-efficient thermal insulation material. |

2.Product applications & projects case
The rockwool metal sandwich panels are mainly used for the following building types:
☆ Commercial buildings:
Office buildings,hotels,restaurants,Cultural and recreational facilities,gyms,etc.
☆ Agricultural buildings:
Poultry houses,Warehouses,etc.
☆ Industrial buildings:
Factory buildings,power plant,Hydropower plant,industrial warehouse,etc.
☆ Residential buildings:
Living house,clean room,etc.
Panel joint way:
There is not joint space,which make the sound insulation and heat insulation performance much more
better than common rockwool sandwich panels.

4.performance description
☆ High fire safety:
Rockwool,we can also called it mineral wool,it has been classified as a non-flammable products.It has been tested as A1,according
to GB/T 23932-2009.Yumi steel can offer the related certificate for your reference.
☆ Acoustic comfort:
Rock wool panel is with sound proof properties,when it's with perforated holes.
☆ Easy installation:
All rock wool sandwich panels from Yumi steel company,is a complete prefabricated element,and can be installed quickly.
Because of speed installation,this can reduce the labor cost.
☆ Various color choices:
We have wide range of colors for your choices,to meet up your building requirement.

Remark: normal temperature status
Compared with other building materials, the PU sandwich panel can effectively prevent cold energy transmission
due to the larger temperature difference between the inside and the outside, so cold storages are more energy-saving
and the working efficiency of cold rooms is improved.
