Most of us have seen the familiar sight of a new home being constructed. Stacks of materials sitting in a top yard along with a small crew of workers cutting and nailing lumber set up to create the framing. What most folks have never seen could be the amazing modern high-tech approach to a method built house. The modular industry has perfected methods to produce a strong, high-quality house at substantial savings.
Through using technology and computer-aided design and computer-aided manufacturing, nearly every floor plan which can be site-built can be built in a factory for 15% to 20% less cost, plus much less expensive time. The normal time frame to build a conventional house may be reduced from six-to-twelve months to three-to-four months of all projects.
In a typical construction timeline, the framing cannot begin before the foundation is completed and cured. In a modular system format, several work packages may be performed simultaneously to relieve the complete completion time. For instance, as the foundation has been poured, your home is also being built in the factory. Then when the building blocks are ready, the home is assembled and shipped for the building site where it is then lifted in place on the inspiration. This process greatly reduces the time it takes to advance into your home and consequently cuts down on monthly costs associated with a construction loan.
The biggest differences in construction are located inside the factory itself. Walls and floor are made with high accuracy because it’s performed in a controlled environment. Specialized machines and tools install the nails and fasteners that bind the structures together. All the material is staged and ready to use in a temperature-controlled building, avoiding the harm and warping that always is the place materials are exposed to the weather in a job site. All the personnel is trained in the area of the specialty inside the assembly and building process.
Because the home will be shipped hundreds of miles and lifted into place having a crane, your home contains 15 to 20% more material. The extra material is required to maintain structural integrity during your house moving and setting process. Doors and window headers are triple planked instead of double planked. The walls are steel strapped to both the floor and roof trusses. Floors and walls are glued, as well as fastened in place. A double-rim joist instead of a single-rim joist surrounds the perimeter of your house where the sill plate will mount, and also the exterior walls are constructed from 2×6 wall studs as an alternative to the popular 2×4 wall studs. All this additional material and awareness of detail generates a structure that is much more resilient than a conventional residential house.
A testament to modular house structural strength is normally found in excerpts from your Federal Emergency Management Agency (FEMA) report following the 1992 Hurricane Andrew in Florida. The Building Performance: Hurricane Andrew in Florida report found “Overall, relatively minimal structural damage was noted in modular housing developments. The module-to-module mixture of the units seems to have provided an inherently rigid system that performed superior to conventional residential framing.” The report also noted that modular homes withstood the ravages of these storm’s Category 4 winds of 131-155 mph far better than site-built housing.
The differences from your modular and conventional home from an energy-efficient standpoint are distinct. A modular home wall construction is foam sealed to stop air leaks. Depending on the geographic location and the local building code requirements, walls may be insulated by having an R-21 value, as well as the roof, which might be insulated with an R-60 value. The R-value measures the insulation’s ability to resist heat traveling through it. The higher the R-Value the better the thermal performance with the insulation. It is common to have a 30% decrease in heating costs in a modern modular home.
It is little wonder that so many purchasers are searching closer at the cost-saving option of having their next house be a system built. All of these differences equal a residence built for the highest standards, delivered quicker, saving the homeowners time and expense. Modular Homes are getting to be the best edge choice in high-tech, energy-efficient construction.
