From dust

First of all, there is an suspended ceiling ceiling with a surface of mineral fiber. Despite the magnificent aesthetic qualities and ease of installation with the help of a unique suspension system included in the set, Armstrong from the mineral -fiber is not suitable for all types of premises. For example, it is undesirable to install it in rooms into which street dust can penetrate in large quantities, for example, in the halls of public buildings. This is explained by the one, the mineral fiber is extremely difficult to clean from dust and it cannot be simply washed. It is also impossible to install suspended ceilings from this material in rooms with high air humidity, such as bathrooms. The reason for this is the property of mineral fibers to collapse and deform under the influence of moisture.
