Factors Influencing Performance
The relative performance of different pipe insulation on any given application can be influenced by many factors. The principal factors are:
- Thermal conductivity ("k" or "λ" value)
- Surface emissivity ("ε" value)
- Water-vapour resistance ("μ" value)
- Insulation thickness
- Density
Other factors, such as the level of moisture content and the opening of joints, can influence the overall performance of pipe insulation. Many of these factors are listed in the international standard EN ISO 23993.

Famous quotes containing the words factors, influencing and/or performance:
“Language makes it possible for a child to incorporate his parents’ verbal prohibitions, to make them part of himself....We don’t speak of a conscience yet in the child who is just acquiring language, but we can see very clearly how language plays an indispensable role in the formation of conscience. In fact, the moral achievement of man, the whole complex of factors that go into the organization of conscience is very largely based upon language.”
—Selma H. Fraiberg (20th century)
“Do you believe that the dead can influence the living?... Could you conceive of a superhuman mentality influencing someone from the other side of death?... There is such a one.... Someone, something that reaches out from beyond the grave and fills me with horrible impulses.”
—Garrett Fort (1900–1945)
“The value of old age depends upon the person who reaches it. To some men of early performance it is useless. To others, who are late to develop, it just enables them to finish the job.”
—Thomas Hardy (1840–1928)
