A prefab house is shortened name for a prefabricated house, which is a home that has components manufactured in an off-site industrial facility. They are sometimes referred to as factory-made or modular homes, although there are some differences. In this type of house, the walls and wall units are made in a factory, whereas modular homes have entire sections of the house build off site. By manufacturing the parts of the house off site, waste is reduced and less time and energy are expended during construction. In addition, the slab put in for a prefab house is much easier to arrange than the foundation of a traditional home.
The benefits of buying a prefab house include ease of mobility, speedy construction, and fewer expenses. These houses are usually less expensive to build and can be put up in only a few days, complete with wiring, heating, and plumbing. The only thing buyers must provide is a plot of land on which to put the house.
Advantages of prefab house:
1)Construction time is reduced and buildings are completed sooner, labor cost can be greatly reduced and allowing an earlier return of the capital invested.
2)On-site construction and congestion is minimized, Quality control can be easier in a factory assembly line setting than a construction site setting.
3)Prefabrication can be located where skilled labor is more readily available and costs of labor, power, materials, space and overheads are lower.
4)Time spent in bad weather or hazardous environments at the construction site is minimized.
Less waste may be generated and in a factory setting it may be easier to recycle it back into the manufacturing process.
Types of prefab house we can fabricate:
a small stand alone building with insulation and electrical connections used as a dedicated office space - similar to studios, summer houses and garden rooms.
They are usually transported by tractor-trailers over public roads to sites which are often in rural areas or high-density developments. Often used for temporary accommodation on campsites. While these homes are usually placed in one location and left there permanently, they do retain the ability to be moved as this is a requirement in many areas.
other than a residential building, including any building constructed for industrial or commercial use. Types can include office buildings, warehouses, or retail.
Installation of SIPs Prefab house:
SIPs construction relies on careful planning and design prior to delivery and site assembly. A completely customized panel layout will be produced, in which all the panels are in numerical order with specific location.
Panels are shipped to the jobsite for assembly when the foundation and deck are in place. After the bottom plate is attached to the perimeter, placement of the wall panels begins. Panels weigh approximately three pounds per square foot, so 4' panels are light enough to be carried and set by hand. Exterior walls for most houses can be erected in less than a day. Nails and adhesive foam are used to fasten the panels to top and bottom plates, and to make vertical connections. Gutter spikes or long screws are often used for SIP corner connections. Walls must be properly braced and plumbed, and interior walls are typically constructed with conventional framing. Beams that carry roof loads may require stud supports incorporated into wall panels, to carry point loads downward. Heavier roof panels are usually set in place with a crane.
To take full advantage of SIPs insulating capacity, care must be taken to seal all joints properly, but the relatively small number of connections makes this easier to accomplish. Spray polyurethane foam is often used to fill any voids or gaps, joints and details.
