The Importance of Residential Insulation

Abnormal high energy bills are caused by improper insulation for any residence. The leakage of air during extreme climate changes makes it hard for heating, ventilation, and air conditioning (HVAC) systems to work at an optimal level.

There may be a need to have your residence evaluated by insulation experts. You must act as soon as possible since improper insulation also causes health hazards to your home.

Places That Need Spray Foam Insulation

Knowing where spray foam insulation should be installed is one of the important steps in home improvement. You must always get the most benefits out of all your investments, including residential insulation.

Different Types Of Spray Foam Insulation

By considering the living conditions and the health of your family, it is highly recommended that you look into having your residence checked for proper insulation. There may be a possibility that insulation has already been pre-installed when you purchased your property. However, it must be checked to see if it is doing its job and if the type of insulation material used is the appropriate type used in certain areas of the residence.

Even with spray foam insulation, it has its own types that should be used in respective areas of the house to benefit from their unique characteristics. Spray polyurethane foam (SPF) is composed of isocyanate and resin. These chemicals are mixed to form the spray foam material. However, there are differences between its types.

Closed Cell Spray Foam

This is a type of spray foam insulation that can be used for both internal and external installation. It has a closed cell composition which creates a rigid and firm material. This ensures that moisture cannot penetrate through the foam material. Also, it can reduce the penetration of sound. This helps reduce noise from entering the rooms that have been installed with this type of spray foam material. It is also denser, which makes it durable enough to last for a longer period of time. With its composition, the Federal Emergency Management Agency (FEMA) has indicated that the foam material is more effective at resisting floods. This makes closed spray foam insulation one of the best types of insulation for residences located in areas that are exposed to extreme climate changes. Another important characteristic of closed cell spray foam insulation is its high R-value rating. R-value is used to measure the ability of any insulation material to resist conductive heat flow. Closed cell spray foam insulation usually has R-value rating between 6.0 and 7.0 per inch.

Open Cell Spray Foam

The main benefit that this type of spray foam material has is its ability to expand more, about 100 times, as compared to closed cell spray foam material. This makes it possible to apply the material on surfaces that have bigger areas. Even though it has an open cell composition, when it comes to the prevention of noise from entering the house, it still offers good resistance to noise. For its thermal resistance capability, its R-value rating is between 3.6 and 3.8 per inch. This makes it better to be used for internal applications. It also costs less than closed cell spray foam.

What Works Best Where

Open cell foam is best suited for application in residential structures especially above grade in roof lines, exterior walls, and attic floors. It is also great for areas that need an effective sound dampener. Closed cell foam works incredibly well below grade in basements and crawl spaces. It is also commonly used in commercial and industrial projects, in exterior applications and for insulating metal buildings and pole barns.
