Thermafiber fire and sound guard mineral wool is thermafiber fire and sound guard mineral wool is designed to provide exceptional acoustic control and fire protection in interior walls as well as floor and ceilings in residential and light commercial construction. The recommended insulation for round chimneys where temperatures are below 300 c is load bearing lamella mats prorox ma 520 alu. These are mounted directly onto the chimney and are fastened with straps. Holes hidden in attics basements and crawlspaces are much harder to locate and usually cause bigger problems.

Its density is not high enough and its binder breaks down at less than 400 degrees f. Once the air seal was accomplished jerome installed a roxul mineral woolinsulation barrier around the chimney. For the future insulation inspection the inspector told us that he wants to see a vapor barrier on the mineral wool we used in the chimney chase. There was no insulation in the chase before and we decided to go with mineral wool over fiberglass batt insulation which can come with its own integrated vapor barrier.

This isolated the masonry from an r 60 blanket of cellulose insulation that was blown in place after all the airsealing measures were implemented. Fiberglass home insulation is not considered an acceptable fire safeing product.
