"If above the ceiling tiles the wall is a finished assembly and there is insulation on or under the roof assembly I would call it conditioned space. Which are has a greater r value or lower u value would not sway my opinion one way or another. I have…"

"I agree with you so far.  But that just means that the vapor barrier is less leaky than the duct.  (If the vapor barrier was more leaky than the duct, the vapor barrier wouldn't move.)  But my experience and test data says that…"

"When the insulation gets larger on supply when the blower is on that's duct leakage.    If the insulation vapor barrier is draw in on return with blower on that's duct leakage.   "

""Most sealing done on ductwork is the insulation"?  How do you figure that?  Do you have any data to support that idea?"

Eric Kjelshus replied to Shaun 's discussion Commercial duct testing
"Most sealing done on duct work is the insulation.   That's why the vapor barrier  is the air seal in most new duct work.   Most new work gets awarded on low price,  no standard - no test out - no low energy goals - no watts…"

"I run into this all the time.  You CAN test those ducts.  If you want a good quality installation - you should test those ducts and they should meet the leakage specified..  A typical installation leaks 30% of the air thru the…"

Commercial duct testing

Hello all,I am a BPI BA, HERS rater and QC inspector. I cant find a ton of information on this topic and I wanted to see what others had to say. Assuming all other qualifying testing parameters are met; If there is a drop ceiling in a commercial office, and it is assembled correctly with no gaps or missing tiles and the drop ceiling is insulated with batts and the U factor of the roof assembly is greater than the U factor of the drop ceiling assembly, can duct testing be done? I have heard from…See More

Eric Kjelshus replied to Shaun 's discussion Commercial duct testing
"I test Commercial just like home - I turn on the blower and turn on AC with out compresses running in winter but above 60' turn on compresses to get a wet coil.   I test presser and size on pipe/trunk that is with out bends or holes.…"

Rich Manning replied to Shaun 's discussion Commercial duct testing
"The IECC code states that the area between a drop ceiling and roof is considered as unconditioned. I don't know why it would be unfeasible to test the ducts, and I'm not sure of the parameters of why they would be tested. Is someone saying…"

Walter Money replied to Shaun 's discussion Commercial duct testing
"Shaun, You can test anything. The question you seem to be asking is 'should I test the ducts under a drop ceiling?' Well, is it conditioned space or not? Does it matter? What do you want to find out? Is the delivered air sufficient? Test…"
