Choosing The Right Type Of Spray Foam Insulation

By Cynthia Cook


Spray foam is a compound that is composed of the mixture of the polyol resin and the isocyanates. These two components usually mix at the spray nozzle during spraying. When you are thinking of using the Spray Foam Insulation, then you need to hire an expert who can assist you and ensure you get the best quality.

While one have to do the form heat sealing, some things need to be understood. First and foremost, foam insulation appears in two forms. One is the open cell in which sealing material is usually less dense and thus does not entirely close the cells. This approach is as well cheaper since little chemicals are used plus it is simpler in the application. Open cell approach provides a proper air barrier. Nevertheless, it is less effective on insulation against water vapor and cannot be applied on the exterior.

Closed-cell is the second type. About this type, it is denser, smaller and compact cell structure, unlike open cell foam. It acts as a good barrier to sound and water vapor and can be applied in the interior and exterior of the house. It uses polyurethane which has low conductivity gas.

When you use the closed-cell insulation, you stand to get numerous benefits even if it is more expensive to use compared to the open-cell. The closed-cell type of SPF application can help to reduce mold growth. It will do this by preventing the moisture from getting into your home. When you can control the growth of these molds, then you get rid of the allergic reactions that these molds bring. In addition to this, you get to prevent your furniture from rotting.

The second benefit of closed cell is that it reduces noise. The applied SPF acts a second barrier to loud noise that may emanate from the environment. Thirdly, R-value- closed-cell sealing material has a high R-value meaning that there will be greater resistance to heat loss or gain. It blocks three forms of heat transfer which include conduction, radiation, and convection.

Just like any other thing with shortcomings, closed cell type of SPF application is also characterized with a few drawbacks. This mostly emanates from the exposure to the isocyanides. If in contact with human eyes or skin, it causes irritation. Thus, use of protective attires is recommended to avoid this as well as ensuring the expert concerned does not leave behind any traces of it to protect the residents.

Moreover, the agents used to drive the spray from the gun are known to contain hydrofluorocarbon elements that are actual agents of greenhouse gases. In concern to this, harmless agents are been sought to be used in the place of the hydrofluorocarbon agents with a significant aim to reduce many emissions going to the ozone during the foam insulation process.

When you weigh the benefits against the shortcomings of the process, you will realize that it is worth the cost. The important thing is to ensure that the installation is performed by a qualified professional in Richardson, TX. To realize these and other benefits of sealing using SPF, consider hiring a professional applicator close to you.
