Home insulation is necessary to keep home cooler in summer and warmer in winter. Home insulation materials are heat resistance. They resist the flow of heat and cold waves. This method is also useful to achieve energy efficiency. The heat is a form of energy and it flows out of home in the winter. It also flows into the home in the summer. Therefore, to achieve energy efficiency home insulation methods are necessary.
Sometimes fiberglass are used to provide home insulation, they can observe sound and heat waves. They are useful to prevent transmission of sound waves from one room to another. They are useful to make out home sound proof. It will increase overall comfort of the homes.
Home Insulation is not just necessary for walls and attics, but they are also necessary for other parts of the home such as ceilings, basement walls, and floors above crawl spaces, knee walls and spaces between interior walls.
The home insulation methods are selected by the R-value of the materials. The R-value is stands for heat resistance. Proper insulation level is identified by R-value of a material such as fiberglass and cellulose. These materials are labeled by R-value. The R stands for heat flow; it provides greater insulating power for material. Most manufacturers are printing R –values for their products.
There are many materials used in home insulation methods such as mineral wool, fiberglass, cellulose, foams and cottons etc. cellulose and fiberglass are most common home insulation materials. Fiberglass, rock and slag wool insulation are used to prevent moisture from home. They can hold water and moisture.
It is necessary to follow building codes while deciding insulation methods for home. These insulation levels are decided by builders or the local building codes. It is also important that the material used in home insulation provide lifelong thermal performance. The insulation levels of a material is judge by the R-value of a material such as the fiberglass insulation products are available with R-values ranging from 11 to 38 per inch, this useful for fiberglass batts and rolls. These materials provide greater energy efficiency and flexibility. These insulation methods are helpful for energy saving and it dose not reduce energy efficiency after sometime and they do not straighten out. Sometimes rock and fiberglass will lose insulations 1 to 3 percent, but they do not influence the thermal performance of the insulation.
Cellulose provide much greater insulation, it has higher R-value. It is one of the most popular types of insulation. Most of Americans are using cellulose home insulation methods. On other hand fiberglass insulation is different from cellulose insulation because it dose not require chemical treatments. It is made from sand and recycled glass. Cellulose insulation is used for ground or crawl insulation methods. It is used to protect crawl area from water, fire and humidity. It has been proved from the study that `cellulose loses their effectiveness after sometimes. Cellulose is not useful to protect from moisture and water because it is made from newspaper. It can reduce energy efficiency.
