Home Insulation Basics: Keep Your Conditioned Air Where It Belongs

Wednesday, October 02, 2013

All homeowners want to find ways to minimize their energy costs as weather gets colder. There are many ways to make your home more energy efficient, from installing a programmable thermostat to properly maintaining your ducts. One of the best and easiest things to do to increase your home's energy efficiency is to ensure that it is properly insulated. There are several different types of insulation, as you will see with these home insulation basics.

Roll and Batt insulation

This insulation comes in rolls or blankets, and is generally made from minerals such as fiberglass or rock wool. It is meant to be placed between floor joists in the attic and wall spaces in unfinished walls. You can get rolls or batts in a range of sizes, and they can be cut to fit the required length. How thick this insulation is affects its R-value. Avoid compressing this insulation, since this will reduce the R-value.

Loose Fill

Made from rock wool, cellulose or fiberglass, loose fill insulation either comes as small pellets or a loose fibrous material. Professionals use specialized equipment to blow this insulation into wall spaces and into attics.


Expanding foam insulation can be delivered in two ways. Homeowners can purchase spray cans of expanding foam that can be sprayed into small holes, cracks around windows and spaces around pipes and vents. Expanding foam can also be used by contractors, who inject the foam into walls and other spaces.

Rigid Foam

Rigid foam insulation is thinner and has a higher R-value than other types of insulation. Because of this and its greater expense, it is used for specific purposes, such as interior sheathing in basements or exterior sheathing of homes.

These simple home insulation basics give you a general idea of which insulation you should use for which purpose. If you have any further questions, please contact us to find a Mitsubishi Electric Contractor in your area. These experienced professionals will be more than happy to help you.
