Roxul vs fiberglass attic.

In damp locations rock wool retains its thermal and acoustic properties whereas fiberglass deteriorates so use the material that works best for the purpose you need it for.

This combination results in a non combustible product which is a major advantage and it means that there are no additional flame retardants in the material. But given that the material is fire resistant water resistant and highly efficient the small amount of extra money you spend on it. A fire can happen to anyone but using roxul can potentially help minimize the damage.

Fortunately roxul has been proven to be more fire resistant than not just fiberglass but virtually every other insulation product on the market. Fiberglass offers an r value of 2 2 to 2 7 per inch while rock wool has an r value of 3 0 to 3 3 per inch making it a slightly better insulator than fiberglass according to the u s. However you can special order r 15 high density fiberglass batts. Both materials are versatile and popular choices among constructors.

It is true that roxul can run up to ten percent more expensive than fiberglass and other insulation options.
