ROXUL Mineral Wool Insulation - Highly Vapour Open
Dr. John Straube of Building Science Corp dispels the misconceptions of mineral wool insulation and identifies some of the many benefits from choosing ROXUL in this 3.5 minute video.

Of particular importance is his comments regarding the vapour permeance of a mineral wool insulation in comparison with rigid or spray foam insulation and why this is so important.
"Some insulation products that have built-in vapour resistance can impede drying and this can become an important concern during design. The resiliency of a wall to built-in construction moisture or accidental flaws in water control needs to consider how that insulation will allow drying outward."
"There are many types of foam insulation but all of them are characterized by limiting vapour flow through them."
"If the design is not taking into account resistant properties of foam, you can trap moisture in a wall or roof assembly, and of course trapped moisture leads to damage such as mould growth, corrosion or decay."
"One of the unique features of stone wool is that it is very open to vapour flow" "This means there are some tremendous advantages if you are trying to dry a wall or roof out or in, because water vapour came move almost unimpeded through the actual insulation product"
