How Do I Know if My House Needs Insulation?

What is the Best Home Insulation?

For homeowners searching for more ways to insulate their homes, there are many options. For homeowners to choose the best type of insulation, there are a couple of things that should first be determined. We recommend R-values for the areas that need to be insulated. R-values are the capacity of an insulating material to resist heat flow. The higher the R-value, the greater the insulating power. Three significant forms of insulation can be applied: cellulose, fiberglass, and spray foam. A consultation with an insulation expert will do wonders for determining the best option for your home.

What is the Cheapest Insulation Material?

Insulation is an affordable way to save money and make the home more comfortable. In finding the cheapest insulation material, homeowners would do well to select their preferred type of insulation, and then shop various sources for the best possible price. Insulation materials range from hefty fiber materials such as fiberglass, rock and slag wood, cellulose, and natural fibers to rigid foam boards and shiny foils. In particular, fiberglass consists of excellent glass fibers and is one of the most common forms of insulation material. Such glass is prevalent in two contrasting types of insulation: blanket and loose-fill. It is also available as rigid boards and duct insulation. A qualified roofing technician can give you a purview of the cheapest insulation material that would benefit your home, customizing your options.

What Happens If You Touch Insulation?

Fiberglass insulation appears far more harmless than it is. Pink, cotton candy-colored fiberglass insulation contains many thousands of small shards of glass and sand. These shards can easily make their way into people’s eyes, skin, or lungs. Fiberglass insulation is not safe to touch with bare hands. People report a stinging sensation that quickly develops into burning and itching. Experts recommend that anyone encountering or using fiberglass insulation wear protective, well-fitted eyewear, heavy-duty gloves, a dust mask, loose-fitting clothing covering the entire body, and a hat keep such particles out of the hair.

What is the Best Insulation for Under the House?

Like the attic, the crawl space under the home needs quality insulation to maximize home energy efficiency. Fiberglass insulation batts or rolls are the most economical and most straightforward DIY choice for insulating between the floor joist in a crawl space. The U.S. Department of Energy recommends R-11 (3 ½”) insulation under floors for homes in warm climates. For properties in cold temperatures, the R-25 (6” to 8”) is preferable. Installation should consist of the paper vapor barrier facing upwards toward the heated living space.

How Long Does it Take to Insulate a House?

Foam insulation is an excellent form of insulation for the home. The amount of time that is required to install foam installation differs depending on the location. For all existing external walls, injecting foam insulation could take 2 to 5 hours. Insulating an attic could take one to two days. A crawl space, which is the area underneath the home, could take two to three hours to complete. Installing insulation around a rim joist usually takes approximately one to two hours. 

The siding of a home provides an admirable and necessary layer of insulation. If your home has brick siding and needs repair, it’s essential to know that you have options.

Which Home Insulation is Best?

The best insulation options for an attic are cellulose, fiberglass, and open-cell spray foam. Open-cell spray foam insulation is an air barrier that creates a seal against air movement. Applications distribute this insulation type through a spray that delivers insulation that can expand up to 100 times its original size. It can fill every single crevice in an attic. The principle ingredients are water-blown and organic chemical compounds, which make this type of insulation environmentally safe. Cellulose has the longest track record, as it is the oldest type of insulation material. It works best for the attic and other areas of the home. Fiberglass, as previously discussed, consists of excellent glass fibers.

Home Insulation for Walls

Homes built pre-1970s through the 1980s rarely have insulated walls unless a retrofit project has already resolved this issue. Uninsulated closed walls, particularly in harsh climates, can result in high energy costs and discomfort. Many contractors suggest injection foam insulation for wall insulation projects. Foam insulation is essential because it resists mold and mildew better than loose-fill, batt, or roll fiberglass. Unlike blown-in cellulose, the strong expansion properties associated with foam insulation mean that it can force its way into difficult to reach areas. These areas include wire, boxes, protruding nails, and screws, and other spaces hung up with gravity-fed cellulose.

Contractor Spraying Home Insulation

Home Insulation Foam vs Fiberglass

Good insulation maintains the desired temperature in your home or business and increases energy efficiency. While spray foam is a relatively new insulation method, it’s become a favorite for contractors and homeowners alike due to its ability to seal off small crevices. Additionally, spray foam insulation does not break down as quickly as fiberglass insulation, making it last longer. On the downside, spray foam insulation is more considerably more expensive than fiberglass insulation. Spray foam insulation is usually three times more expensive than fiberglass insulation.

Home Insulation Basics

Homeowners are encouraged to consider an insulation strategy for maximized performance. With lowered utility bills being the goal, homeowners should consider the following strategic advice. The three essential considerations for insulation are:

  • What type of insulation material is best for your budget and needs?
  • Where is the best place to install the insulation?
  • How much insulation is needed?

Going over these questions with a qualified technician can significantly assist with determining what is necessary for your home.
