The Importance of Compliance
It is important to note that unlike traditional or open web joists, one test with one i-Joist manufacturer does NOT give you automatic approval with any other manufacturer.
However it is also acceptable to NHBC Building Control to use the test to demonstrate compliance for other engineered joist floors where the key elements of the test are the same or better. These elements would include:
Common Engineered Joist Types
*Not Air Leakage Or Acoustic Rated
*Not Air Leakage Or Acoustic Rated
*Not Air Leakage Or Acoustic Rated
30, 60 And 90 Minute Fire Resistance Periods
Fire Resistance Minimum Periods (Minutes)
