In a previous thread, ROBMARK said the following:

Quote:

You had asked for a pic of the soffit/air supply. The original plans called for the ductwork to run within the soffit, but due to size limitations, that was changed. What I did was have the duct boxes mounted in the drywall as if they were going to place the grills in the drywall. I then constructed the soffits, and once the bottom of the soffits are in place, I will attach the grills directly to the MDF. Robert

(See attached picture of Robert's soffit)


Question: I am in the same boat as Robert as my soffit is not big enough to run the flexduct as originally planned. If I use the same technique as Robert, do I need to be concerned about isolating the inside of the soffit? Besides noise, I'm more concerned about condensation forming and over time causing damage to the ceiling drywall/soffit.


Thanks,

Not sure why, but the picture didn't get attached to the post. Let's try this again.


Okay - still will not work, but here is a URL that should work...

I used 1" semi-rigid duct liner inside my bulkheads that are being used as ducts. Not only helps with any condensation but adds some sound adsorption.

Thanks - that's what I am planning on doing too using some of the Linacoustic RC left over

Curtis,


I haven't finished the insides yet. According to my AC guy, since I'm dealing with a pretty small area, it would not be absolutely necessary to cover the MDF with anything. However, he said that if I have the material around, I might as well...but only because of condensation issues.
