Can this safely be applied directly to the outside of a heating duct? If so how, just tape?

You can use mass loaded vinyl on the outside of SOME heating ducts. But you need to be sure that the heat level is not too high for the material. Assuming this is not a high-heat application, I'd actually recommend you go with our Luxury Liner Pro product. It comes with a fused closed-cell foam decoupling layer that allows the MLV to "float" off the duct. This creates a double wall effect and improves performance. Wrap the Luxury Liner Pro around the duct. Hold it in place with mechanical fasteners every few feet. Wrap the entire thing in foil tape.

Is this 1lb/ sq ft? Is it reinforced?

This listing is for the 1/4" 2lb per sqft option. We sell it in 1lb per sqft also. The tensile strength of either option is 600 PSI.

Yup. Luxury Liner is typically cut with a sharp utility knife.

how do you mount this to an apartment wall?

Normally it goes under the drywall, directly over the studs. But in buildings that are more restrictive of construction add ons, you would need to apply it on the wall with bolts with large washers that are drilled into the studs through the drywall. It is used on the walls between you and the noise and needs to be in full coverage across the wall to perform best.
