A mass wall is a heavyweight wall, typically exhibiting a unit weight greater than 15 lb/ft2. While many professionals (and even code reviewers!) presume that any wall system containing concrete and/or masonry qualifies as a ‘mass wall’ with regard to energy codes and standards, it might not necessarily be true.
What Is a Mass Wall?
In architecture, a mass wall is a load–bearing wall that is made of solid masonry and has a large mass or weight.
This type of wall is often used in traditional construction, as well as in modern construction. Mass walls are usually made of brick, stone, or concrete, and they can be either structural or non–structural.
Mass walls are often used to support the weight of a building, as well as to provide thermal insulation.
