Major Differences Between Spray Foam and Fiberglass Insulation For Commercial and Residential Application

Tips

If you are planning to insulate your new home, one of the major things that you should consider is to choose the type of insulation that you will use. Two of the most common options for insulation are fiberglass or foam insulation. Since insulation plays a critical role in buildings and houses, it is important that you carefully choose the type of insulation to use. Insulation is used to provide resistance to the heat flow, which increases the efficiency of cooling and heating components. Choosing the right type of insulation for your house is very crucial because it determines the quality of performance and at the same time, allows you to cut cost. Basically, according to engineers, one of the important factors that needs to be considered when choosing the type of insulation for your house is the R-value of the insulating material. R value refers to the capacity of the insulation to resist heat flow. Technically speaking, the higher the R-value, the greater the power of insulation. To help you out, this article will go through the differences between fiberglass and spray foam insulation.

Spray Foam Insulation

According to most engineers, spray foam insulation is the most preferred choice due to its capacity to provide high moisture resistance feature. This is because of the cellular structure of spray foams. With millions of tiny barriers of this insulating material, it has the ability to resist the migration of liquid. Aside form this controlling moisture characteristic; spray foam insulation also ensures that it delivers long-term and steady thermal performance. When it comes to indoor air quality promotion, spray foam insulation has also an advantage. Usually, spray foam insulation doesn’t have fibers or formaldehyde and only has low volatile organic compounds. There are two types of spray foam insulation; open cell and close cell. Open cell foam is spongy, soft and impermeable to air but permeable to moisture. Open cell has 3.6 to 4.3 R-value per inch. On the other hand, closed cell foam has 6 to 7 R-value per inch. It also becomes rigid when applied to the surface. There are also some benefits of using spray foam insulation such as noise reduction, pollen and allergen prevention, long lasting and eco-friendly. However, spray foam insulation kit is significantly more expensive compared to other types of insulating materials.

Fiberglass Insulation

Fiberglass insulation is different from spray foam insulation. This type of insulation is usually packaged like rock wool in loose fill or rolls. This insulation is made of glass fibers that are thin, lightweight and cost effective as well. This is usually a practical choice used for both commercial and residential applications. Fiberglass insulation is also insusceptible to dampness and burning due to its glass structure. Additionally, compared to spray foam insulation, fiberglass is significantly cheaper. It offers lower cost and can be installed even without using any costly devices or equipment. Just like spray foams, fiberglass is also effective in reducing noise. With its millions of fiber that trap pockets of heat when applied to crevices and cracks, it allows sound proofing ability. Fiberglass has 2.9 to 3.8 R-value per inch. 

According to experts, any of these two insulating materials are effective. But with some differences, it is important to carefully consider and determine your needs and preference. Factors like prices, effectiveness, R-value, and materials are very crucial when choosing the right type of insulation. So whether you are insulating your new house or upgrading the old one, or for commercial purposes, it is necessary to use insulation with the right type.
