Denim Insulation Installation

Much has been written about alternative insulation materials and this houseblogger gives a thumbs up to denim insulation. They found it easy to use, easier to install, and effective.

The insulation hangs in sheets 8' high and 16' on center and she scored it with a utility knife and then tore it by hand. Since the insulation is non-toxic only a dust-mask was needed.

The cross bars or stay rods or tiger teeth can be used but normally they have a kraft facing that is adhered to it on the sheet rock side. But if you wanted to put tiger teeth behind thats fine. But the sheeting to encapsulate it is the way International code/LEEDS is recommending now

Most places no longer use vapor barrier. After years of installing it they opended old walls and found moisture/condensation had formed in the wall. Places like Alaska still use it but Washington State, California and Texas I know for sure no longer use it nor require it.

To make this insulation more efficient you need to put some type of backing like thin ply wood or even a cardboard type material. To encapsulate the cavity and will enhance the R factor of the material.

Also, no vapor barrier -? - is this also not necessary with this type of insulation?

We aren't sure. Best to shoot an email to the houseblogger and ask. This photo isn't the final product.

It doesn't look like the cross bars were utilized. Are they not necessary?
