Introduction To Home Insulation

Attic insulation is one of the home improvement processes which are done to keep the temperature moderate inside the house. The insulation is done most probably in extreme hot and cold climatic conditions. The purpose of insulation is the same but the types and style of insulation employed is entirely different. Insulation is also done for secondary reasons like pest resistant, noise barrier, energy saver, reduction of utility bills, etc… The below paragraphs shows the type of insulation based on the seasons. The insulation is done either in the hot climatic region or cold climatic region. Insulation in hot climatic areas: In a hot climatic condition, the hot air enters and accumulates into the house through wall, attic, etc… and lets the cool air to pass out. This happens despite using the electronic cooling equipment which in turn increases the usage and shows rapid increase in the utility bill. Insulating the house will prevent the let-out of cool air. As the radiation level is more in hot temperatures, the insulation also serves as the radiation barrier. The types of insulation used in a hot climate are listed below.

Blown-in attic insulation: As the name suggests, the insulation is implemented by blowing the insulation in the wall or roof in high pressure with the special equipments. Blown-in insulation is done in all types of insulation materials like fiberglass, cellulose and rock wool. There are three main type of blown in insulation used, they are loose fill, wall cavity spray and stabilized type. Blown-in cellulose insulation is the eco-friendly process of insulation, as the material is made from the recycled paper. They are cheaper and can easily fill into the small air spaces and this insulation is implemented in the walls, attic floors and small and tiny places.

Rolled-in insulation: Unlike blown-in, this is the flat piece like insulation materials available in layers. The small layer of materials is taken and the space is filled. This comes under the blanket category. The insulation material used in this type is the fiberglass and rock wool. They carry negative effect in filling the small spaces. This type is very expensive and can be handled easily even by the less experienced workers. Rolled-in insulation doesn’t require the special type of equipment for the installation. They can be implemented in walls and flat floors and ceiling which are devoid of gaps and wires.
