Conclusion

The use of sealant on metal buildings is beneficial in a number of ways. First, sealant can protect the metal from the elements, keeping it looking new and preventing corrosion. Second, sealant can improve the energy efficiency of the building by reducing air leakage.

Third, sealant can improve the indoor air quality of the building by reducing the infiltration of airborne contaminants.
