The first water-based centralized heating distribution systems were put into operation in 1880 in the United States. These systems are known today as first-generation heating distribution networks (1G). Until the 1930s, steam steam was the only coolant. Continue reading
Application of mounting foam and sealants in construction
In this publication, we will consider what constituent foams and sealants are, their composition, properties and characteristics, which should be considered when purchasing.
