[] Prefabricated Homes Primer

has posted a new item, 'Prefabricated Homes Primer'

This is by no means an exhaustive list of what's available in the area of
prefabricated homes and buildings. This article is to introduce you to the world
prefab. If you're in the industry, you'll probably be cringing about now at the
word "prefab". But, the word is one that has become synonymous with homes and
buildings that have been partially or fully assembled in a factory setting.I for
one am excited to see the latest versions of modern prefabs emerging globally.
They're well thought out, beautiful, and energy-efficient.And to anyone who has
any doubts about the quality of today's prefab homes, I'd ask, would you rather
buy a house whose parts have all been crafted outdoors exposed to the elements
-- by hand. Or, would you rather buy a house built in a factory setting to tight
specs exceeding that of site-built homes. I say exceeding, because a normal
site-built home doesn't have to endure the rigors of transportation.For your
review, here are quick descriptions of 10 of the many categories of prefab homes
available for exploring at http://PrefabExpo.com - in no particular order:1.
ManufacturedSingle-family residential dwellings consisting of one, two or more
sectional units and constructed to Federal HUD code. Zoning regulations and
ordinances of the local Municipality or County might not permit use of mobile
and manufactured homes in all areas of their jurisdiction.2. ModularModular
refers to a method of building a home, rather than a type of home. A modular
home can be built in a factory from a stock modular home plan or from a
customized plan, to the state, local or regional codes of where the home will be
set up. Modular homes have not typically experienced the zoning restrictions and
discriminative ordinances applicable to manufactured and mobile homes.3.
PanelizedPanelized homes are factory-built homes in which panels whole walls
with windows, doors, wiring, and outside siding are transported to the site and
assembled. Panels are made from insulating foam sandwiched between two layers of
structural material. The panels are lightweight and might already be filled with
insulation when they arrive on the site. The homes must meet the state or local
building codes of where they are sited.4. Steel-frameSteel framing is an
equivalent to conventional stick frame or post & beam home design where the
structural lumber is replaced by steel studs and trusses or steel posts and
beams. Light-Gauge Framing System features screw-together, galvanized
stud-and-truss, grid-type construction system built on 4-foot center.Red-Iron
Metal Post & Beam Systems features bolt-together, pre-engineered
post-and-beam-type framing system that uses the red-iron steel "C" beams on
8-foot center. The prefabricated home built with this method can be
single-story, two-story, and even tri-level home.Unlike conventional wood framed
home that requires interior walls to support the roof, the higher
strength-to-weight ratio of steel house allows to span greater distances with
less material and fewer supports. The result is higher floor layout and interior
design flexibility.Unlike wood, steel won't shrink, rot, warp, buckle, split, or
be attacked by insects. This results in greater durability, lower long-term
maintenance, higher energy efficiency and overall greater quality of this
prefabricated home.5. PrecutThis category includes wood-framed factory-built
houses or cabins where building materials are factory-cut to design
specifications and transported to the site to be assembled. PrefabExpo.com
presents prefab building kits designed as wood-framed (also known as
balloon-frame, 2 x 4, 2 x 6 or stick-built construction) as well as
prefabricated home kit/cabin kit using post-frame method. The homes or cabins
must meet local or state building codes of the area where they will be sited.6.
CedarAccording to Katahdin Cedar Log Homes, Cedar is aromatic to people, and
problematic to insects: The heartwood of northern white cedar produces organic
compounds called thujaplicins which create that fresh, pleasant cedar aroma.
But to insect pests, such as moths and termites, cedar just plain stinks. Theyll
avoid cedar homes and instead search out inviting, tasty pine structures.Cedar
home kits include everything you need to build the home, itself. That is to say,
the walls, the floor, the ceiling, the windows and doors. But your foundation,
plumbing and electrical system are not usually included in a kit.7.
TimberframeTimber framing is a specific type of post and beam construction in
which a frame is created from solid wood timbers that are then connected by any
one of the following wooden joints: mortise and tenon, dovetails, or scarfs
secured with hardwood pegs. The frame is covered with any one of a number of
enclosure systems. Normally the timbers remain exposed to the interior of the
building.Timber frame structures exhibit a strength and aesthetic quality not
found in conventionally framed houses. The timbers are pre-cut, shaped, and
finished at the factory, then sent to the construction site, where they can be
quickly assembled by a crew, using cranes to lift the bents and beams into
place. Joinery is the heart of the entire structure.8. LogLog homes provide
their owners with a comforting and relaxing sense of informality and simplicity.
The mass of logs produces heating and cooling benefits, and reduces noise
transmission into and throughout the home. These are very attractive
characteristics, but there are also challenges in construction and limitations
in decorating. These aspects require special design considerations and have
unusual maintenance requirements.Basic Kits Are... WALLS ONLY: The walls-only
log home package includes all the logs for the outside walls, including
fasteners. Roof beams and staircases may be added. STRUCTURAL SHELL: Shell This
package includes everything that's in the walls-only package, plus all
components necessary to keep the weather out, such as exterior doors, windows,
and the roofing system. THE COMPLETE PACKAGE: Complete packages also includes
interior components required to finish log homes. Such items include interior
walls, stairs, closets, interior doors and trim.9. CircularThe circle is the
strongest geometrical shape we recognize, and this factor likely influenced
builders of circular homes for thousands of years. Prefabricated circular
buildings have been built as cabins, studios, homes, offices or community halls
and convention centers.Most of today's prefabricated circular homes and cabins
offered across the country use conventional wood-frame or post & beam
construction method. These homes and cabins are ideally suited to take the full
advantage of locations offering exciting panoramic views, and to incorporate
factor of the surroundings into the home design.10. DomeGeodesic Dome is using
triangular networks forming hexagons and pentagons and creating a free-span,
spacious environment of spherically shaped structure requiring no internal
supports. This results in large flexibility for utilizing interior space to
implement floor designs not limited by structural restrictions. Because of the
structural strength of the shape, the domes have a far better record of
withstanding tornados, hurricanes and earthquakes than cube-shaped structures of
conventional homes.Advantages...MATERIAL COSTS: Geodesic domes provide the
greatest amount of floor area with the least amount of surface area, reducing
the quantity of needed building material by as much as 30-50%. ENERGY
EFFICIENCY: As a result of the shape, the dome has approximately 30-50% less
roof and wall area than cube-shaped home of equal floor space. This results in
lesser area being exposed to the elements, resulting in reduction in heating and
cooling costs of dome shaped structures. Also, the spherical shape of the dome
facilitates natural air flow yielding more even temperatures maximizing overall
interior temperature comfort. Disadvantages... As a result of complicated
angles, the interior and exterior finishing of the dome (after speedy assembly
of the prefabricated shell) is significantly more labor intensive than finishing
the conventional house. Also, the finishing work requires highly skilled or
specialized tradesmen which might not be available at every location. These
factors might present welcoming challenge for the skilled handyman/homebuilder,
but would create substantial cost outlay if hired labor is considered.I for one
am excited to see the latest versions of modern prefabs emerging globally.

ABOUT THE AUTHOR Diane is co-creator of the Prefabricated Homes and Buildings
website, PrefabExpo, located on the Internet at http://PrefabExpo.com and enjoys
showing buyers everything that's available to them in the way of Prefabricated
homes, cabins and buildings. - Many people nowadays are turning to
"organics" and "naturals" otherwise known as herbals. The rising popularity of
herbal supplements has created a new fad if not a new health lifestyle. But
before you join the bandwagon, here are some things you need to know about this
mean, "green" dietary supplementing machine. What is the difference between a
drug and a dietary supplement? According to the definition set by food and drug
administrations in different countries, drugs are chemicals that can prevent,
prolong the life, treat other effects of a health condition, improve the quality
of life, and/or cure ailments and diseases, or alter the function of any part or
chemicals inside the body. These drugs have approved therapeutic claims. For
example, paracetamol is a drug given to bring down the body temperature in
fever. Ascorbic acid is indicated for the treatment of scurvy. Iron supplements
are given to treat mild cases of anemia. Herbal supplements are not classified
as drugs but as dietary supplements. The main difference is that they do not
have approved therapeutic claims unlike in the case of drugs. Moreover, dietary
supplements could either contain vitamins, minerals, herbals, or amino acids,
all aimed to add to or supplement the diet of an individual. They are not
intended to be taken alone as a substitute to any food or medicine. Most of the
manufactured medicines we now have once came from animals and plants. Through
the years, chemists isolated the life-saving or life-curing components and
separated them from the harmful ones. This lead to the further drug research and
drug development that lead to the production of a different variety of drugs for
many ailments and conditions from synthetic sources. But still we have
semi-synthetic drugs, as well as drug that more or less approximate more natural
composition. Since herbal supplements are made from a mixture of crude herbs
reduced into powder or gel form, and later on packaged as tablets and capsules,
there is a possibility that life-threatening or at least body chemistry-altering
components are still present, thus the expression of concern from the medical
community. Is there a growing concern with the use of herbal supplements? Yes.
With the rising popularity of using and consuming anything herbal or organic is
the proliferation of fake herbal supplements that threaten to endanger lives. If
that's the case, then why are herbal supplements given drug administration
approvals? One way of ensuring the safety of the people is to have all candidate
drugs, food, drinks, and dietary supplements registered with the proper
authority. Otherwise, they would pose more risk with these things being sold in
the black market for a hefty sum. We could ensure the quality and safety of
herbal supplements if they get proper classification with the food and drug
administration. Moreover, people may be able to file the proper complaints in
the event a worsening of health condition is proven to be linked to the use of a
particular herbal supplement. Is using herbal supplements worth the risk? Yes.
It cannot be discounted that many who have tried herbal supplements experienced
an improvement in their health--whether this is due to the herbals themselves or
due to a placebo effect, as long as they do not worsen the condition of an
individual, then using them is worth the risk. But of course, certain things
must be considered before taking those herbal supplements: Your doctor knows
best. First of all, clear your condition with your doctor. Ask him/her if
taking a particular herbal supplement is safe given your health condition.
People with heart, liver, or kidney trouble or malfunction, are usually not
advised to take these, or at the minimum is to take these herbals in minimum
amounts. All substances pass through the liver and kidney to be processed and
filtered respectively. Kava, which is used to relieve people from stress, has
been pulled out from the Canadian, Singaporean, and German markets because it
contains substances that cause liver damage. Certain herbals such as Ephedra
used for losing weight, contains chemicals with heart-inducing effects that can
increase heart rate, which in turn can exhaust the heart and cause heart attacks
in several documented cases by the American Medical Association. Follow the
directions for use. Never take more herbal supplements than what is directed by
the doctor or as instructed on the bottle. Each individual reacts differently to
the components of herbal supplements. While it is perfectly safe for one
individual to take in a supplement of primrose oil capsules, another person may
be allergic to it. So, do not even think about downing one bottle of It has no
approved curative effect. No matter how the product pamphlet or the label of the
bottle sounds about how it has been found to be helpful in certain health
conditions, these herbal supplements are not therapeutic. So do not substitute
these for the medications prescribed by your doctor for the treatment of certain
diseases, or for the maintenance of blood pressure, lowering of blood sugar and
cholesterol, and fight off infections.
