The word Prefab is used to describe any type of home that is made from
easy-to-assemble building sections that were manufactured off-site,
climate-controlled factory. The sections are then transported to
the building site. Full sections of the prefabricated home are then
assembled on the ready-made basement or foundation to manage lower
labor cost and site time.
B. Advantages of prefab house:
Construction time is reduced and buildings are completed sooner,
labor cost can be greatly reduced and allowing an earlier return of
the capital invested.
On-site construction and congestion is minimized, Quality control
can be easier in a factory assembly line setting than a
construction site setting.
Prefabrication can be located where skilled labor is more readily
available and costs of labor, power, materials, space and overheads
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.
C. 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.
- Vocational house
Prefabricated homes are rising steadily in popularity among certain
types of home buyers in recent years. Retirees who plan on living
in a residence permanently often buy prefabricated homes. Second
home buyers are also in this group as they often use the home for
family recreation and not as a future investment property. The new
state of PREFAB homes encourages more people that are looking for a
cost-effective and custom, permanent primary residence to choose
E. Main construction materials used for our Prefab house:
- OSB facing SIPs
- FC facing SIPs
F. 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
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.
