The Best Insulation for Your Home: What to Look For


It’s crucial to insulate your home correctly. Insulation prevents heat loss in the winter and reduces heat gain in the summer by slowing thermal energy transfer. Your energy bill will decrease, and your comfort level will increase year-round with better insulation that keeps the heat in during the winter and the cool air in during the summer.

There are three factors to consider when deciding what kind of insulation to put in your home: the material, the type, and the location/application. There are four common varieties, and each has advantages and disadvantages.

Insulation All-Around

The most popular form of insulation is blanket insulation, which can be purchased in batts or rolls. There is a wide range of widths and thicknesses for both the batts and the rolls. Fiberglass is the go-to for blanket insulation. A facing is attached to several types of blanket insulation to make a vapor and air barrier. Kraft paper, vinyl sheeting, and aluminum foil are all examples of common-facing materials.

The fact that the homeowner may install batts is blanket insulation’s main selling advantage. Installing blanket insulation in a home can be a quick and easy, but there are certain things to keep in mind. One major drawback of DIY blanket insulation is the need for protective gear due to the presence of microscopic fiberglass particles. Wear a mask and protective clothing when installing blanket insulation; breathing in the tiny fiberglass fibers released during the process can be dangerous.

Blanket insulation might be tricky to install in an area that isn’t perfectly flat. The efficiency of blanket insulation is diminished if it must be fitted around electrical and plumbing, which can be time-consuming. This insulation is ideal for unfinished walls, floors, and ceilings (including foundation walls).

Insulation Spray Foam

Liquid foam insulation is frequently used in spray insulation. Fluid foam insulation can be applied in various ways, including spraying, injecting, pouring, and foaming. Spray foam insulation is typically made of polyurethane. Installing spray foam insulation can be more expensive than using blanket insulation. In contrast, the lower weatherizing costs and more significant savings over the lifetime of sprayed-in foam insulation result from its higher R-value (a measure of insulation’s capacity to restrict the rate of heat movement).

Spray foam insulation’s primary selling feature is its ability to fill in the spaces and crevices of an application’s cavity or space. After curing, it won’t move, settle, or fall out of position, preventing moisture buildup (thus reducing the likelihood of mold and mildew).

The installation process is the primary disadvantage of spray foam. Spray foam insulation is typically installed by a specialist. If you try to save money by doing the job on your own and mess up the spray foam installation, you’ll have a huge mess to clean up, and your home’s structural integrity will be at risk. The cost of spray foam insulation is higher than that of other materials. Existing finished areas, around obstacles, unfinished attic floors, and enclosed existing walls are all ideal candidates for spray foam installation.

Foam-like Rigid Insulation

You can insulate anywhere with rigid foam insulation (or rigid panels). Rigid foam insulation is more expensive and more time-consuming to install than blanket insulation, R-value for R-value. Rigid foam insulation is preferable because of its high R-value per inch of thickness. Compared to blanket insulation, which only provides a partial air and moisture seal, rigid foam is superior. Rigid foam is more convenient to set up than spray foam. Cutting rigid foam to size is simple with a sharp knife. Rigid foam’s lack of adaptability is its primary flaw. Because of its rigidity, it is challenging to install in particularly tight or asymmetrical spaces. It’s ideal for low-slope roofs without ventilation and unfinished walls, floors, and ceilings.

Rigid Foam Board

Small fiber, foam, or other things make up loose fill insulation. Like spray foam, loose-fill insulation can be shaped to fit its intended location. Cellulose, fiberglass, and mineral wool are the most often employed materials.

Loose fill insulation’s primary benefit is that it may be stuffed into cracks and other spaces with an irregular shape. It’s one of the few insulation options that won’t ruin your walls or floors when you put it in. The major problem is that its R-value drops as it settles over time. Its heft is also a disadvantage. A drywall might slump if too much loose fill insulation is used.

Since the weather in each region varies, it’s essential to consult a professional in your area who specializes in insulation. Consider the insulation specialist’s track record while making a hiring decision. They know what will improve a house over time and can offer advice tailored to your project.
