About Siding

Muna wa Wanjiru asked:


To help to protect our homes from the harsh elements many of us use different types of sidings. These sidings can be natural wood sidings like that of Cedar wood or log sidings. We can even choose steel sidings, aluminum siding, vinyl siding and even log vinyl siding.

Log vinyl siding is made from vinyl but it has been created to resemble real wood sidings. The log vinyl siding will be patterned as if you were looking at cut logs. This means you have a choice of having the smooth finish of the inside wood or you can choose the rustic look of the rough outer log covering.

Log vinyl siding is a cheap alternative to real wood sidings like Cedar wood which is usually used. In the log vinyl siding the siding has been designed so that you can place the various trims and J-channels that are needed for the installation of the vinyl siding in places where they will blend in with the imitation wood.

As you are installing the log vinyl siding you should take care that the pattern of the logs is visible and also that you have allowed enough of the vinyl siding material to account for the various weather conditions.

This is because even though log vinyl siding looks like real log siding it has a tendency to have water seepage damage occurring and sometimes the siding will buckle and warp. This damage factor occurs when there isn’t enough room left from the installation process for thermal expansion.

When you are buying log vinyl siding you will need to see the best way that you can attach this siding to your home so that the various elements will not affect the look of the log vinyl siding. You should be able to find vinyl siding manufactures who can provide you with information to prevent these types of mishaps.

When you are installing the log vinyl siding you should make sure that you have enough of the vinyl siding available for any mistakes that occur as you will need to replace the entire panel. While this type of vinyl siding is a popular option to full log siding you might want to see the advantages and disadvantages to be found with log vinyl siding.

For the proud homeowner there are many different colors and textures that log vinyl siding can be found in. You should look at these sidings to choose the type of log vinyl siding that will prove to be an asset for your home for many years to come.

Vinyl Chloride is perhaps something that is not widely considered; however, is more widespread than most people know as it is used in so many manufacturing processes. There are many regulatory measures in place regarding its use.

The American Chemical Society (ACS) assigns a Chemical Abstracts Service (CAS) registry number too many different chemical compounds for identification purposes. The CAS for Vinyl Chloride is 75-01-4.

The ACS keeps documentation on research and events which involve Vinyl Chloride and are an excellent resource for these materials. The Environmental Protection Agency (EPA) is another body regulating vinyl chloride.

The EPA has calculated an inhalation unit risk estimate of 8.8 10-6 (g/m3)-1 for lifetime exposure to vinyl chloride.

Vinyl Chloride itself is a flammable, colorless, sweet smelling gas. However, OSHA has classified vinyl chloride as a hazardous chemical with a permissible exposure limit of 1 ppm (part per million), at which level it is impossible for the human nose to register a smell. Thus, if a person were able to smell vinyl chloride this would be indicative of an egregious overexposure.

Vinyl Chloride is also known by the names chloroethene, chloroethylene, chlorethylene, ethylene monochloride, monochloroethene, monochloroethylene, VC, and vinyl chloride monomer. It is supplied commercially as a liquid under pressure.

Vinyl Chloride is used primarily in EDC (ethylene dichloride) plants, in methyl chloroform plants, and, most frequently, in PVC (polyvinyl chloride) processing and fabricating plants. Vinyl chloride monomer is the compound from which PVC is derived. PVC is used to make a plethora of different consumer products including, but not limited to:

* Vinyl siding.

* Plastic cards (credit, ID, etc.).

* Window profiles.

* Pipe/plumbing/conduit fixtures.

* Insulation.

* Clothing and upholstery.

* Flooring.

* Roofing membranes.

* Electrical cables.

* Containers.

* Battery cell separators.

* Phonograph records.

* Irrigation systems.

* Latex paints.

Clearly, individuals working in or around any location or manufacturing plant utilizing vinyl chloride should be aware of the risks inherent in exposure to this chemical. Indeed, those working in PVC plants receive a higher dosage of vinyl chloride than those employed to create it.

In the past vinyl chloride was also used as a component of aerosol products, and also for medical applications. Now though, it is illegal to employ vinyl chloride as an aerosol propellant according to the Consumer Product Safety Commission, the EPA, and the FDA.

The Clean Air Act and the Clean Water Act both mention a reduction of vinyl chloride emissions and usages as necessary to avoid adverse health effects. In both pieces of legislation maximum exposure and contamination amounts are defined.

The EPA is the government body which has the authority to regulate vinyl chloride as established under the Resource Conservation and Recovery Act of 1976. The FDA has disallowed using this substance in pharmaceuticals, and in any materials used to contain consumables.

Not only have the uses on vinyl chloride been restricted, but according to the Emergency Planning and Community Right-to-Know Act of 1986 one or more pounds dispersed into the local environs (air, water or soil) must be stated and registered with the Toxics Release Inventory established by the EPA.
