Three Construction Methods That Laid the Bedrocks to Factory Prefab Homes

Modular Home
Factory Prefab Homes

As an introduction, manufacturers construct modular homes off-site in a factory over just a few days, and anchor them on the site after completion. Call your new home flat pack, LEGO blocks, or a modular home—they are all the same, with noted technical exceptions. Below are construction methods that laid the bedrocks to three prominent factory-based prefab homes.

SIP Module-Wise Construction

The SIP module construction method got originated in America of the 1950s. SIPs are a materialistic method to building a prefab house. Structured Insulation Panels consists of Styrofoam cavity sandwiched in between Oriented Strand Boards (OSB). For instance, the OSB may be of the size of 7/16 inches being the outer layer of the sandwich and 5½ inches Styrofoam being the inner layer. As you can see, the benefits of SIP module-wise construction include cavity-based insulation, thermal resistance, airtight assembly, and fast-tracked factory process.

Cross Laminated Timber Framing

CLT is a type of flat pack modular home where the materials may size half a foot and feel robust like the prefabricated steel. Home builders use Cross Laminated Timber prominently because they can bear the load of a prefab structure to its walls, floors and roof. The CLT panels tend to have gaps to place pre-cut windows as well as patio doors, and are assembled on the site. CLT offers flexibility in construction and alternative home designs to a homeowner, and can also be insulated with batten strips.

Modular or Volumetric Construction

Volumetric construction produces three-dimensional modules in a climate-controlled factory, and then transported to the site for final assembly. In volumetric prefabrication, builders assemble 90 percent of the modules in the factory, and reduce landfill waste dramatically. In fact, builders can transport modules in different shapes, such as a basic structure or one filled with upright interiors. Using volumetric construction, builders may prefabricate a dwelling in up to four modules, and construct the home’s roof on-site.

Home builders prominently use timber-frame prefab methods to build their three-dimensional modules. The present emphasis, however, is on Cross Laminated Timber. Furthermore, you may hear terms such as green home, LEGO brick construction, and pod-type modular home. These are all derivatives of default prefab housing.
