Types Of Basement Insulation

In order to know how and why you should be insulating basement floors, walls, and ceilings you must first understand and learn to identify the various types of insulation. The four different types include; blankets, rigid board, loose fill, and spray foam. Each one are different an vary based on the type of room it is being used in, how it was built, and what features you are adding to your home.

Loose Fill Insulation

The loose fill basement insulation is made up of fiber pellets or loose fibers that are blown directly into the opening in the walls or ceilings. This is one of the more expensive types – but it is one of the easiest to install. You will have no troubles trying to fill in all of the cracks and holes and it will reduce the amount of leakage that can occur.

Cellulose fiber is a common substance used for this type of insulation. It is produced from recycled newspapers that have been chemically treated to withstand and resist moisture and fire. This can be used in the walls and floors and provides your home with reliable insulation.

Blanket Insulation

Blanket insulation is a type of mineral fiber that is made of either rock wool or fiberglass. This is commonly used to insulate the walls and ceilings. This is considered to be the most affordable type of basement insulation that you are able to use. However, it must be done very carefully.

This is best used on a standard joist, rafters, or in between a stud spacing of sixteen to twenty four inches. You will be able to find these in such widths that will allow them to fit securely between the wood framing members. There are others that might be found with a radiant barrier backing or in long rolls that will be cut to the length and width you need.

Rigid Board Insulation

This is made from polystyrene, fiberglass, or polyurethane. You will be able to find this in many different types of thicknesses. It is also one of the most common to use inside the basement walls. This needs to be covered with ½ inch gypsum board or other types of materials that are fire resistant and approved by certain codes.

Spray Foam Insulation

Spray foam basement insulation is made up of polymer and a type of foaming agent. This is sprayed through a small nozzle that fits neatly into the wall, ceiling, and other areas. As it is being sprayed into the wall it will expand into a solid cellular plastic that is made up of millions of tiny cells full of air.

This type of insulation should only be used by a professional. It requires special equipment that will mix it, meter it, and spray it into place. This is slightly more expensive then most other types of insulation – but it will keep you from having to take the steps to keep things air tight.
