What's your experience with Duct Sox?
(OP)
I have seen some duct sox in operation at the Gym for about two years now. I have an application for such a thing but I hesitate about the durability and maintenance of this material.
I've seen some with a type with linear slot of holes and a other totally perforrated types. I can see that it helps spread the airflow throughout the open space evenly without having the draft of a 4000 CFM round diffuser damping air into people's bold heads. Very light and easy to install material, and not so bad looking.

Take the "V" out of HVAC and you are left with a HAC(k) job.

On a follow up:
How did you sell it to the architect and the owner? was it easy to sell or did they actually originate the duct sox application? and were there truely real costs savings compared to sheet metal?

A couple of things that can be a big driver on costs are the type of fabric and the color chosen. If you stick with most manufacturers "standard" (i know there can be a lot of variation here) fabric and their standard colors you will see some significant savings. When you go to premium fabric or non-standard colors those installed savings start to diminish. Also, cost savings start to disappear with more complex lay-outs.
One other gotcha in regards to installed costs is whether or not the contractor is familiar with it. An unfamiliar contractor may figure it will take the same amount of time to install as spiral since they probably don't have any numbers to go by. It is a much, much faster install.
Finally, I have found it very easy to sell to both architects and owners. Owners like it because of the lowered install costs. Architects like it because it is very easy to work with and gives them a lot of options. As with most systems that we deal with the best way to sell it is to take the clients to another installation. Once they see it in action they are usually sold.

I have even used them on VAV jobs, the key is getting the fabric duct supplier involved early in the job and keeping the lines of communication open. VAV is possible with fabric but it must be pointed out in the design stage,(the ducts need to be designed at with at least .25" esp on the lowest setting to keep the duct fully inflated, this may raise the esp on the highest setting, just make sure the equipment can handle it.)
jobs I have used the fabric on :
Natatoiums (fully agree with vannic here)
gyms
warehouse
office space (halfround ducts work well and look decent also)
hockey arena
library (if balanced/designed right they are quiet)
One neat thing about them is the colors can be matched to school colors (although adds cost) and even mascots can be placed on the ducts. I had one school order several sections with company logos on them and the comapnies paid to have their section up fuctioning in the system but also advertising for their company. The school had their duct system paid for in 2 yrs!!
Be careful with high inlet velocity and turbulence at the inlets as this can make the duct visibly move or vibrate!! Most say 1400-1600fpm inlet velocity, be sure to have the manfuacture give you a layout with dimienision etc.
Duct sox is the big brand name out there but shop around as I have used a few different manufacturers and have had satifactory results (the danish companies seem to be the most experienced, as this product is claimed to have been produced there first) Just make sure the company has a UL listing and can provide written technical data, performance gaurantee, warranty, etc.

Size, Length, CFM needed, etc. (static pressure)???
Any help???

Better would be to go to www.ductsox.com and find your local rep.
