Does mineral wool insulation need a vapor barrier?
Yes, mineral wool insulation does need a vapor barrier. This is because mineral wool insulation is made up of spun plant fibers, rocks, and coke, and it is considered a type of air barrier that stops the flow of air and more importantly, moisture.
Without a vapor barrier, moisture can penetrate the insulation, making it less effective and leading to water damage. Moreover, mineral wool insulation is hygroscopic, meaning that it is designed to absorb moisture, so it must be protected from vapor and condensation with a vapor barrier.
A vapor barrier is usually a thin plastic sheet like a polyethylene that is installed on the “warm side” of the mineral wool insulation. This plastic sheet is designed to create a vapor-tight seal and prevent air and moisture from entering the space into which the mineral wool insulation has been installed.
Installing a vapor barrier with mineral wool insulation is a critical part of the building process, and failure to do so may lead to decreased insulation effectiveness, increased risk of water damage, and increased energy costs.
Does mineral wool have an R-value?
Yes, mineral wool does have an R-value. R-value is a measure of a material’s resistance to heat flow, so the higher the R-value, the better it is at insulating – and mineral wool is one of the better insulating materials.
Its R-value ranges from 3.3 per inch for loose-fill to 4.0 per inch for multilayer board; however, it’s important to note that these values are for a 2-inch-thick layer with an air space on the back side.
When compressed, its insulation value decreases, so in order to maximize its R-value it’s important to provide adequate space. Mineral wool is also classified as a fire-resistant insulation, adds structural strength to a building and is safer to handle than fibreglass insulation because it doesn’t contain binders or irritating fibres.
Mineral wool insulation typically is installed in spaces such as attics, walls and floors.
