There are several types of insulation methods available for home insulation. However, the types of insulation methods that work best really depends on a couple of factors such as the amount of insulation needed, the space to be insulated, the accessibility of the area to be insulated, insulation price and the local expertise of local contractors. Therefore, the question of which insulation methods work best will probably have to be addressed in a different article. For now, we will only look at the types of insulation methods in this article.

The most common types of insulation methods available are batts or roll, blown-in loose-fill, foam, rigid, reflective and radiant barrier. Each method has its own advantages and disadvantages. One insulation method that best works in an area might not be suitable in a different area. Some methods are expensive but last longer and more effective while some are cheap but may not be effective. Therefore it really depends on which space that you want to insulate as well as your budget in order to apply the intended insulation method. We will discuss each of the insulation methods in detail in the following paragraphs.

Blankets in the form of batts or rolls
Batts or rolls are flexible insulation materials made from mineral fibers such as fiberglass or rock wool. They are best used for areas like the wall studs, attic or floor joists where they have a standard spacing as batts or rolls can easily be cut to fit into whatever widths are available in these areas. Non-standard spacing areas such as the area in between joists near windows, doors, or corners can also easily be fitted with batts or rolls that are hand-cut and trimmed. In areas where there are obstructions such as wires, electrical outlet boxes or pipes, you can easily avoid insulating these areas by trimming and cutting the batts or rolls to the exact shapes and sizes. Simply put, batts or rolls insulation materials are the choice of most home users as they are cheap and can be easily installed either by homeowners or professionals. Some batts or rolls are available with or without vapor-barriers facings. Batts with a special flame-resistant facing are available in various widths for basement walls where the insulation will be left exposed.

Blown-in loose-fill
Blown-in loose-fill insulation is a type of insulation method which uses a special pneumatic equipment to blow insulation materials such as loose fibers or fiber pellets to an area. This type of method is usually handled by a professional installer and it is difficult for homeowners to do it on their own as the equipments are expensive to buy. Blown-in loose-fill is best used in wall cavities. In addition, it is also appropriate for unfinished attic floors, for irregularly shaped areas, and for filling in around obstructions.
In some cases, cellulose and fiberglass fibers can be mixed with an adhesive or foam and after that the mixture is sprayed to areas such as open wall cavities. Blown-in loose-fill insulation is more expensive compared to batts or rolls and only used for insulating certain spaces.
