Although it’s long been popular in residential construction in Canada, mineral-wool insulation (also known as rock-wool insulation) has mostly been limited to commercial building in the United States. Thanks to a renewed push from manufacturers and a growing interest from builders, mineral wool is starting to gain traction among builders in the States, particularly because of its inherent fireproof, watershedding, and chemically inert qualities. Residential designer Mike Maines takes a close look the material, from its basic traits to best practices for installation. A chart shows how mineral wool compares to other insulation materials in five categories: R-value, water-vapor permeability, airflow resistance, fire control, and sound control.

Only the loose particles are bad for you lungs. I use a 3M respirator and gloves when installing mineral wool just as I would when installing fiberglass. As far as off gassing most off the insulation materials in use today release off gasses. However nothing fills a cavity better than rock wool; unless you decide to use spray foam.
If you have a large job I’d recommend a cutting table for precise cuts. One can be made from easily sourced materials: plywood, door hinges and two saw horses.
user-6087192, we had to chop down roughly 30 pages of writing into a 6-page article with lots of images, so yes, some information does not make the final cut. We addressed your safety concern by saying that respirators are recommended. We also address offgassing: there is very little with mineral wool; some formaldehyde is used by most manufacturers but it is almost entirely baked off at the factory.
The problem with these types of sites is that they always leave something out about each product.This stuff is bad for your lungs.Everyone knows the nightmare that homeowners have had by using great products that are bad for your air.Also alot of the basement insulation touted offgasses,thats a future pet peave.
