4 Types of Insulation

There are many different types of insulation used in homes and commercial buildings. The need for insulation is common nowadays because of the need to save on energy cost. Most homes are insulated using different types of insulating materials to prevent heat from escaping during the winter season, and preventing too much heat from entering the home during hot summer days. Insulation saves on energy bills because it offers lower home heating needs during winter. Here are four of the most common types of insulation.

1. Blanket Insulation

Blanket insulation makes use of mineral fibers such as those processed from rock wool and fiberglass. This type of insulation is so called because it comes in rolls of blankets. Blanket insulation can be used on walls, ceilings, and floors. Although this type of insulation is the least expensive among all four, it requires careful attention during installation to become effective.

2. Rigid Board Insulation

Rigid board insulation can be made out of different materials including polystyrene, polyurethane or fiberglass. It comes in different thicknesses and is used as a very effective insulation material. It can be used to insulate ceilings and walls, especially in the basement. It can also be used as an effective sound barrier and can therefore be installed in recording studios, churches, and commercial areas to insulate sound. When installing any of these insulating materials, make sure to check the local codes for any requirements or permits prior to installation. Usually, these boards are covered with moisture barriers and other protective covering such as drywall. When these materials are to be installed outside the home, they are usually covered with weatherproof material to protect it from the damage caused by external elements.

3. Loose-fill Insulation

Loose-fill insulation makes use of loose and fibrous materials from fiberglass, rock wool and cellulose. Cellulose fiber is made out of materials from old newspapers. Fire resistant cellulose fibers should be used during application because they provide better fire safety. Usually, fiberglass and rock wool are used for this type of insulation. These materials are blown into the cavities of walls using equipment designed to fill the interior spaces of walls. Although this is the most expensive of all insulation types, it provides the most effective insulation. Because the fibers fill out the entire space inside a wall, it provides better thermal and acoustic insulation as compared to the other types.

4. Spray Foam Insulation

Spray foam insulation is a very flexible way of insulating a home because it does not need to conform to any size and shape. The problem lies with its use though because it may create irregular insulation when done improperly. This type of insulation is a mixture of foaming agent and polymer agent. When applied, it fills the area with liquid foam that quickly expands to form into solid plastic. Spray foam creates better insulation than blanket type insulation because it forms an airtight barrier. A professional may work on the insulation process on a home during large insulation projects. However, small insulation projects can be DIY.
