Insulation Mineral Wool Board

Coning mineral wool insulation products are used in residential and multi-family construction as nonstructural thermal-insulating materials in floor-ceiling assemblies, attics, crawl spaces and walls. In exterior walls, it can be used as continuous insulation in the building envelope, and within interior walls, it can be used as acoustic insulation for partitions. Mineral wool is commonly used in curtain wall perimeter fire containment applications because of its fire resistant properties. In commercial applications it can be used as continuous insulation in the building envelope. Additionally, the high density of mineral wool insulation offers excellent sound absorption properties, making these products an integral part of overall wall systems designed to reduce sound transmission.

Installation

As a semirigid product that is easy to cut and install, its flexibility allows it to conform to building shapes and construction irregularities. It comes in standard-sized sheets and is easily cut with a serrated knife. The boards and batts can be friction fitted in between studs with the ends of each piece butted closely together to fill all voids. Mineral wool can also be mechanically attached depending on the application. Rainscreen and cavity wall systems vary greatly from types of hangers and how they are installed. Generally, mineral wool insulation is installed with abutted joints and mechanically secured and attached to the building substrate without the need to tape joints.
