Having good insulation will save you money. While most people do not pay attention on how many times they turn on the electric fan or their aircon system, little is observed on how much a good home installation can save money in the long run.
But what is home insulation and why it is needed?
Depending on the type of material, insulation aids your home in maintaining temperature by slowing down the transfer of heat or coldness as well as sound from one area to another. It is usually installed on walls, windows, roofing, crawlspaces, basement walls and other areas. Think of it as a blanket or an inner layer that protects your home in between walls. Insulation is best installed during the construction phase of a house as the walls and ceilings are not yet sealed. If a home is well insulated, money is saved by cutting energy/ electricity bills (up to 50% in the long run!).
So what type of materials should you use?
Insulators are measured by R-value or thermal resistance of the material. The higher the R-value the higher the insulating effectiveness (Wikipedia). Take note though, the right R-value for your home will depend on various factors such as your region and climate situations. Insulators can be made up of Fiberglass, mineral wool, cellulose, spray foam.
Fiberglass, usually the cheapest are mostly used for insulating attic/ roofing areas. Mineral wool on the other hand, is usually expensive and the material is hard to find. It is also usually used for soundproofing because of its rigidity. According to RetroFoam, cellulose installation is the oldest form of home insulation as it is made up of recycled newsprint. It is mostly used at enclosed existing walls, open new walls, and unfinished attic floors. Spray foam is a polyurethane product which is lightweight, durable and versatile insulation solution. However, depending on the application, some homeowners experienced difficulty in breathing during the installation works. Thus, it is recommended to hire a contractor who will handle the job.
