3、ts in low-rise residential and light commercialstructures.The majority of fenestration units selected for installation in these types of structures arecertified as meeting specified performance characteristics in standardized laboratory testing.Experi-ence indicates,however,that the performance of f
4、enestration installations is frequently significantlyinferior to the performance of the manufactured units in laboratory testing.Installation of fenestrationunits can significantly influence in-service performance.The requirements promulgated in this practice have,by consensus,(of individuals with s
5、pecializedknowledge concerning installation of fenestration units)been identified as necessary to ensure thatas-installed performance is roughly equivalent to performance in laboratory testing.The task groupresponsible for development of this practice recognizes that building owners sometimes,accept

7、d withensuring that as-installed performance is comparable to the capabilities of the units installed for a solidmajority of installations.A particularly noticeable behavior that indicates deficiencies in installation is rainwater leakage.Rainwater leakage has been the leading reason for dissatisfac
8、tion of building owners with performanceof fenestration installations.For this reason,this practice places greater emphasis on preventing orlimiting rainwater leakage than on any other single performance characteristic.This practice emphasizes that the water-shedding surfaces of fenestration units m
