An Ode to Spray Foam

You may have heard about using spray foam insulation throughout your home, garage, and attic—but did you know that spray foam insulation can also be used on your roof’s exterior to prevent leaks and provide additional thermal insulation?

This video demonstrates how spray foam insulation is applied to a flat roof. As the foam expands, it provides a moisture-proof protective barrier which will help to prevent leaks and regulate your home’s indoor temperature.

What is Spray Foam Insulation?

Although fiberglass has been the industry standard for home insulation for several decades, there are now many other materials available that are far more effective at sealing the home and preventing heat and moisture transfer. The most well-recognized of these is spray foam insulation. In this post, we’ll take a look at what spray foam insulation is and how it compares to other types of insulation.

How It Works

Spray foam insulation is made from polyurethane, an organic compound that is used in a number of different products, including foams, plastics, and fabrics. Polyurethane foam is actually a combination of two chemicals that are mixed together at the jobsite and then applied directly to the wall frame. These two chemicals react, which makes them expand and harden in the wall or ceiling frame. This allows the insulation to fill in all gaps and cavities in the wall for a perfectly air-tight seal.

Open-Cell vs. Closed-Cell

Spray foam insulation comes in two varieties: closed-cell and open-cell. Closed-cell foam insulation creates a completely air- and moisture-resistant barrier, which gives owners are a higher R-value and greater insulation performance. Open-cell foam insulation is permeable to both air and moisture, and is a great option for homeowners who prefer a less dense insulation option. Open-cell foam insulation will allow your home to “breathe” more, while still providing impressive insulation performance.

Effectiveness of Foam Insulation

When it comes to performance, spray foam insulation is far more effective than any other type of insulation available. In addition to providing better R-values per inch than fiberglass or cellulose insulation, closed-cell foam insulation can also act as a vapor barrier, which blocks out moisture and prevents the growth of mildew and mold in your walls. Spray foam insulation is a great choice for homeowners seeking maximum energy efficiency and greater comfort.

About Guardian ATS Insulation

When you choose to upgrade your insulation, you will have plenty of choices. Take a look at this video to learn about one of your options.

In this video, you will learn about Guardian ATS insulation. The ATS, or air tight system, is a new form of insulation that combines the benefits of traditional fiberglass and new spray insulation. The first component of the ATS system is a spray insulation that fills gaps and voids in the wall. It can also reach hard-to-reach places. Foam insulation’s other major benefit is the fact that it forms an air barrier that protects your home from allergens. Once the spray foam has been applied, the fiberglass insulation is installed to form a thermal barrier.

Using Radiant Barriers in Conjunction with Other Types of Insulation

Poorly insulated attics can dramatically increase your energy costs, especially during the summer. Increased heat transfer means that more heat from the outside gets into your home, leading to an increase in air conditioning costs. Installing radiant barriers can help reduce this heat transfer, reducing your energy costs in the long run.

• What are radiant barriers?

Radiant barriers are made out of highly reflective material. When installed in your attic, they help to reduce heat transfer by reflecting sunlight away from your home. There are many different kinds of radiant barriers. Reflective foil, metal, reflective roof sheathing, and other materials can all be used to help reflect sunlight away from your roof.  Another benefit of radiant barriers is that you can apply them to any kind of insulation.

• How will they save energy?

As the temperature increases during the summer, you’ll have to work harder to keep your home cool. Because are attics are directly beneath our roofs, they are in many ways more vulnerable to the sun’s heat. Once your attic has become hot, the warm air then circulates throughout your home. This will increase your energy costs and put immense amounts of pressure on your air conditioning system. Radiant barriers can decrease your energy costs by keep your attic cool.

• How are radiant barriers installed?

In order to get the maximum benefit out of our radiant barriers, they must be installed properly. For this reason it is imperative that you find a certified installer to take care of the project. There are many different ways to install radiant barriers, and the decision is made based on the type of house, the specific type of insulation, and the structure of the attic, among other factors.
