1. Pay attention to rainproof during construction of stone wool insulation board, and can not construct in rainy weather.

     2. For cold insulation, a moisture-proof layer must be added. Under the condition of particularly low temperature, resin-free rock wool is used for insulation, and the moisture-proof layer must also be fireproof.
     3. When the temperature exceeds a certain temperature, such as 200°C, proper external protection must be added to the insulation, so that the thickness and bulk density of the stone wool insulation board will not change.
     4. Regarding the insulation of large-diameter and flat-walled equipment with rock wool products, when the temperature exceeds 200℃, be sure to keep in mind the instructions of the rock wool board manufacturer: add insulation nails, (spacing about 400mm), the outer protection should be tight.
     5. Appropriate coatings can be used for equipment, heat preservation nails and pipes for corrosion protection. In addition, there should be no leakage. This can achieve better results.
     6. The finished product of stone wool insulation board, which susceptible to mechanical abrasion under the condition of outdoor insulation, should be covered with metal or plastic. Then pay attention to the joints and the sealing of the joints. If necessary, add glue seals.
