Does anyone know the difference between Roxul Mineral Wool RHT boards versus RHF?

First of all and this is not a joke, where in the world are you? In different parts of the world different companies' names for different products vary. For example, Roxulo has two different types of insulation with the same name in the United States and Canada!

Within Canada, the difference between the two products you mentioned is the binder used. More expensive binder for higher fire rating. The MSDS data sheets can be usefull in looking for differences between seemingly identical products.

Have fun!
