IsoDoor V

The IsoDoor V was sound tested most recently in 2018 as an inoperable individual door at Intertek. The results of this test is available upon request.

COMPARING PERFORMANCE

Unfortunately, the accuracy and consistency of STC tests varies greatly depending on the lab and the year testing was completed. The majority of testing we have found is no more recent than the mid-1990′s with some testing back to the 1960's. To make it worse, many of the tests were done in the manufacturer's own facilities in labs that cannot accurately measure the ranges tested.

Because of this, a competitor’s STC 52, unless tested recently, is not necessarily better than an STC 46 from us. Or a competitor’s STC 46 , unless tested recently, is very likely much worse than an STC 46 from us. The STC calculations are constantly changing and becoming more stringent, and new acoustics labs are more accurate than ever. We tested our line of IsoDoor in 2012 in an acoustic lab known as the most accurate lab in the United States. Our ratings may appear lower than some of the highest ratings you will find, but we are confident that our STC numbers will meet or exceed the competition and can be duplicated both in the lab and in the field.

COMMUNICATING DOORS

We suggest creating a communicating door assembly to increase isolation significantly beyond the IsoDoor HD. Our tests show STC/OITC ratings with the IsoDoor HD as high as 65/50 which meets or exceeds double stud walls. Combining the IsoDoor V with the IsoDoor HD or combining the IsoDoor HD with the IsoDoor HD LF will help avoid common resonance issues that occur when two similar materials are installed in the same assembly.
