Rockwall insulation is a type of insulation that is commonly used in residential and commercial buildings. It is a form of rigid board insulation that consists of two outer layers of solid material, typically made of cement or calcium silicate, with a core layer of insulating material sandwiched in between. The core material is usually mineral wool or fiberglass.
The name "Rockwall" is derived from the combination of "rock" (referring to the mineral composition of the core material) and "wall" (indicating its intended use in wall insulation). Rockwall insulation offers several benefits, including thermal insulation, fire resistance, and sound absorption.
