Preparing for Fall: Insulation Options To Keep Your Home Warm

By Mike on September 10, 2014

Summer has come to an end and winter is quickly approaching. It is almost time to turn on your heater if you haven't already! Now is the perfect time to protect your home against the cold.

With the autumnal season comes cold weather and a big increase in energy bills. One of the most telling signs of a poorly insulated house is when you notice your energy bills are sky high, but your house remains chilly enough that you are wearing a sweater and slippers. If that was you last winter, schedule a free quote to have us look at your home's insulation before you start handing over your paycheck to your energy provider.

Properly insulating your attic and crawl space can save you quite literally thousands of dollars over the course of the next 10 years. On many occasions, our customers have found that their insulation job pays for itself over the course of one winter due to the decrease in energy required to heat their home.


So, what types of insulation are best? While we go into great detail on this topic in our free eBook, we’ll give a quick idea of the stats.


Fiberglass Insulation:

The most common choice of insulation is batt fiberglass. It’s effective insulating qualities and inexpensive price make it a popular option for insulation. It has quality enough to do its job, without costing a fortune at the onset. With an R-value per inch of 3.1 - 4.3, fiberglass insulation will keep your home energy efficient and toasty warm.

Downside to Fiberglass Insulation:

Fiberglass works best in large flat areas that do not have multiple cross beams or obstacles such as wires or outlets, as these will create air pockets and gaps that will diminish its effectiveness as insulating your home. At Clean Crawls we can counteract this at times by combining blown insulation in addition to the batted rolls.

Also, fiberglass that’s exposed to moisture will have its insular qualities greatly diminished. The water will take the place of air in the gaps between the fibers. Because water so easily conducts heat, it allows the heat to escape from the home.

Spray Foam Insulation:

Spray foam insulation is the most effective insulation on the market today. It has the highest R-value, coming in at R-6 per square inch. Spray foam insulation (we recommend the closed-cell type) also provides an air seal and moisture barrier.

As the insulation is sprayed onto the surface of an area, it expands to fill all nooks and crannies. This makes it ideal for areas that have many obstacles that would get in the way of batt rolls. Its rigidity also provides a structural support for your building.

Downside to Spray Foam Insulation:

Unsurprisingly, considering its top-notch insular qualities and moisture barrier capabilities, spray foam insulation is the most expensive type of insulation on the market. However, we feel that this is well offset by its greater capabilities and the fact that it frequently outlasts other types of insulation.

We can also use a hybrid approach for clients. We recommend using spray foam insulation on the first two inches of the area to get the benefits of the air seal and moisture barrier. The remaining area may then be filled in with less expensive insulation, such as fiberglass or cellulose.

Cellulose and Cotton Insulation:

The most common forms of natural fiber insulation are cellulose and cotton insulation. Cellulose is made from recycled plants fibers such as newspapers, and cotton insulation is most commonly made from recycled denim.

These types of insulation come in batts and as blown-in insulation. It’s R-value ranges from 3.5-3.8 per inch. Because both cellulose and cotton insulation are made from primarily recycled materials, it is a common choice for homes that want to be eco-friendly.

Because this insulation is blown-in, it is a common choice for areas that have many obstacles, such as wires, outlets, etc. It is also frequently used to fill wall cavities in homes that do not have insulation or had that insulation removed. A hole can be cut into the wall and the insulation blown in to fill it.

Downside to Cellulose and Cotton Insulation:

Both types of insulation should not be exposed to moisture. The fibers will absorbe water and they are very difficult to dry. Additionally, cotton or cellulose insulation will develop mold or mildew if the damp areas are not dried out completely or removed.
