Notes on size, shape, dimensions of materials in these Mod 2 drawings:

  • Stone Exterior is made of blocks 8″ in depth and 16″ or 8″ in Height. In the Axonometric drawing start from the top with 2 courses of 16″ block, then alternate 8″ and 16″
  • Air Space or Cavity is 2″ and should be free and clear of any debris or mortar.
  • Rigid Insulation is 2″ thick, and is a bare minimum for thermal standards
  • The Vapor or Moisture Barrier (shown as a dashed line) is a film or fabric and therefore has a very thin dimension.
  • CMU (Concrete Masonry Units) are 8″ in depth and are the support or backup for the exterior and interior wall materials and construction. The CMU wall also contributes greatly to thermal insulation, sound and provides a minimum of 2 hours of fire protection.
  • Metal Studs are 5″ in depth and about 3 1/2″ in width, C shaped and locate them at each inside and outside corner and no greater than 24″ apart from each other
  • Gypsum Wall Board (GWB) Is the interior wall surface and is 5/8″ thick. (Less than 1″)
