Is a Cement Floor or Floor Joists More Cost-Effective in House Construction?

Floor Joists

• Floor joists are wooden beams spanning the floor’s surface, providing necessary support for the plywood layers installed over them. They are bridged or cross-bridged for extra support. These joist systems are typically less expensive than is a cement slab. The joists leave room for plumbing and electrical work, and experienced contractors can set up the boards without waiting for anything to cure or dry.

Cement Slabs

• Joists appear are best for saving money. However, cement slabs have their cost advantages that are hidden in location and variables. If you live far from timber, transportation costs are higher. If concrete supplies are plentiful and nearby, slab installation prices may actually fall beneath joist installation. Compare local estimates.

Joist Spacing

• Joist spacing is a factor when estimating any floor joist project’s cost. Joists spaced farther apart lead to fewer materials and less labor, which are cost savers. Joists spaced close together quickly increase costs. Most joists are spaced about 16 inches apart, according to codes. However, closer or wider spacing is possible.

Insulation

• Consider insulation needs before making your choice. Joists and crawl spaces beneath provide room for adding insulation. Cement slabs easily transfer heat. This may add extra costs in heating and cooling bills in the years for controlling the temperature above the floor.
