This invention is a structural building stud that provides interior cavity space for insulation. It also affords construction time savings for in-wall infrastructure systems such as wiring, plumbing, telephone, networking, etc. The common building method is to use solid lumber studs which have the thermal characteristics of conducting thermal energy between the separated air spaces. This invention breaks the conductivity of the two wall surfaces and also provides time savings during the construction period by affording the interior cavity space for in-wall infrastructure. Building corners and spaces behind partition ties are easily assessable for a complete insulation barrier. This invention is comprised of two vertical upright pieces separated by additional spacer blocks to maintain consistent cavity. These pieces are connected by gang-nail plates, nails, screws, glue or other fasteners or methods. The interior cavity space between the two vertical upright pieces provides a thermal break for energy efficient construction. This space can be filled with insulation as well as providing room for in-wall wiring, plumbing, etc. The spacer blocks are also usable for attaching wiring to the studs.
