Because warm air can carry more moisture w/o causing condensation than cold air. If you had the moisture barrier at the cold side warm moist air would hit the cold surface and fall out as condensation, leaving water in the insulation.

Absolutely not. You tape the seams between panels to improve the vapor barrier characteristics of this product, but the foil faces of Tuff R (and any other polyisocyanurate insulation product) are your vapor barriers.

Faced insulation has a vapor barrier attached to one side, while unfaced insulation does not. The vapor barrier helps prevent moisture from entering the insulation.
A vapor barrier in sidewall insulation is almost always a good idea.
When installing insulation be sure to install a vapor barrier on the correct side of the insulation for the region in which you are located.
The best materials for sauna insulation are typically mineral wool or fiberglass, as they have good heat retention properties. Additionally, using foil vapor barriers can help improve energy efficiency. Properly sealing any gaps or seams in the insulation is also important for optimal heat retention.
The actual function of an insulation contractor is that they can skillfully install thermal, vapor, smoke, and all other different sorts of insulation.
To effectively insulate your basement floor, you can use rigid foam insulation boards or spray foam insulation. These materials can be installed directly onto the basement floor to help prevent heat loss and improve energy efficiency in your home. Additionally, you can also consider installing a vapor barrier to prevent moisture from seeping through the insulation.
Insulation should only be stapled on the edge of the stud. That's what the flap on the edges is for. This creates a vapor barrier and if you compress the insulation enough to staple on the sides this reduces the insulation at that point. Insulation has to be fluffed to get the benefit. It is easier, quicker and does not interfere with the sheetrock in any way.
To effectively insulate an attic with floor boards, you can install insulation batts or rolls between the floor joists. Make sure the insulation is the right thickness for your climate and that it is installed snugly without gaps. Additionally, consider adding a vapor barrier to prevent moisture buildup.
Yes, a vapor barrier is typically recommended with faced insulation to prevent moisture from entering the wall cavity and causing potential issues such as mold growth or structural damage.
A vapor barrier underlayment made of materials like polyethylene or rubber is recommended for basement floors to provide insulation and protect against moisture.
