"insulation"When you hear the term “insulation” your first thought may be a residential home. Insulation doesn’t usually help you picture a commercial building. Because we do a lot of work on commercial buildings and warehouses, we write a lot of blogs on this part of the industry. Skyline Roofing does work with residential homes as well. Insulation is an issue we are concerned with as it’s right under your roof. In this blog, we’re covering insulation, how it benefits your home, and alternative options for more health-conscious homeowners. First, we’ll start with the few negatives and end on the positives.

Flawed Insulation

Poorly installed insulation can lead to problems that carry throughout your whole house. Poor ventilation can be the first sign of insulation being placed improperly. Easy fix: check your vents. If the temperature changes more abruptly than usual, it could mean insulation is not evenly placed throughout your attic or roof panels. If the problems are bad enough, we suggest getting a home inspection to look for solutions to insulation issues and others that may be going unnoticed.

Good Insulation = Energy Efficiency

Insulation is not just “stuffing” to be used to fill empty spaces in your attic or roofing panels. It doesn’t only apply to homes in colder states. The purpose of insulation is to keep heat energy from spreading. Therefore, in warmer states such as the south, it will keep outside heat from entering your home. In colder states up north, insulation will keep the heat in. When done right, a one-time expense on the proper insulation will save on your ongoing energy costs.

The effectiveness of insulation resisting heat is given a term called “R-value.” R-values are given based on the make and consistency of the insulation. Adam’s Roofing out of Elk Grove Village, Illinois summarized the three most common types:

Blanket Insulation

Fiberglass, mineral wool or natural-fiber blanket insulation comes in various thicknesses up to R-38, and in standard widths to fit between framing joists. The main drawback of installing blanket insulation on an attic floor is that it’s almost impossible to avoid gaps in the coverage, especially around obstructions and penetrations.

Spray Foam Insulation

Spray foam insulation is a mix of chemicals that expands to fill a space. Available in open-cell or closed-cell types, it’s usually professionally applied to the underside of a roof. Closed-cell offers a higher resistance to heat flow, but the R-value achieved depends on how well/thick it’s applied. It’s the most costly type of attic insulation, but it can be a good option if you plan to finish your attic.

Loose-fill Insulation

There are two main types of loose-fill insulation; fiberglass and cellulose. Both are installed using a blower that fluffs the material to create air pockets and is ideal for insulating an attic’s small or oddly-shaped spaces and hard-to-reach areas. However, fiberglass insulation resists mold and decay, it retains its R-value long-term, and it’s the most cost-effective option.— Source: Adam’s Roofing

Some Added Truth About Blown-In Insulation

Although blown-in insulation comes with its own options on materials, the process is quicker than installing sheets. That’s one major upside to choosing this type. A second upside is simply the level of coverage you receive. Because blown-in particles are smaller, they get into every nook and cranny. This process is feasible because they expand around and lock in pockets of air. Insulation panels cannot get into the corners, along with any uneven surfaces, and around joists. You’ll also be able to add thickness if the first application is not thick enough. Additionally, you’ll be able to customize your insulation. If you want certain areas to be thicker than other to perhaps save money, this is the route to go.

For those homeowners who put their health higher on the totem pole, there are healthier alternatives. These can be blown-in as well and the best options do not include formaldehyde, chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). Be sure to find the blown-in insulation made “from soybeans or castor beans and polyurethane foam. Like its chemical cousin, soy-based foam forms a total air barrier by filling voids and crevices to prevent air intrusion.” As an added bonus, these types are inert, meaning they “will not support moisture or mold, and are durable.” — Source: Bob Vila
