Owens Corning and paint?

[matthewah]

If you were to spray paint Owens Corning acoustic material would you reduce the absorption capability of the product? Would like to hang some acoustic panels that will not be too noticeable, however they would be more noticeable if left the yellow color.

Ok, so the more I think about it the more I'm sure it would reduce the absorption as the paint would not allow the sound to pass through, but to start relfecting. I'm assuming fabric is the best.

I don't believe code will allow untreated exposed glass fiber. If this is a DIY project, you'd better make sure that it complies with code.

In fact they seem to potentially be getting much stricter on this. I have heard from two reliable sources that some authorities are starting to prohibit things like batt insulation above ceilings and there is apparently a renewed push to eliminate fiberglass duct lining. Basically, some people seem to believe any exposed porous materials, especially in an air path, represent a potential health risk. This could be a major concern for acousticians as not only would it limit the options available to them but many of the alternatives tend to be much more costly and thus less likely to be implemented.

It needs to be covered with an appropriate (rated) cloth. And be advised that a rated absorber covered with a rated cloth might be an assembly that is not rated.

This stuff comes covered, and is rated: http://www.primacoustic.com/index-panels.htm
