Spray foam insulation is an excellent way to control your home's temperature. It has many practical benefits over other types of insulation. It is also easy to install and use on different roof types. If you want to know more about its benefits and how spray foam works, keep reading.
How Spray Foam Insulation Works
Spray foam insulation works by sealing up areas where heat and air can escape. It is also known as spray polyurethane foam, and its components include polyol (resin) and isocyanate. Spray foam doesn't stick well to all surfaces, so the roofer must prepare the area before using it. The foam expands to seal off small cracks and gaps between walls and roofing material.
Types of Spray Foam Insulation
Spray foam insulation comes in two different types: open and closed-cell. Each works differently and has different effects. Here is more information about the two types.
Open Cell
Open-cell foam insulation is lightweight and easy to install. It fills in gaps and crevasses very easily. It also dries quickly and is more flexible and moldable. It is best for situations that don't experience extreme moisture or temperatures.
Closed Cell
Closed-cell insulation is denser and more insulating than open-cell insulation. In many cases, this insulation type can add to your home's structural integrity. However, it can also be heavy and add extra load to the structure. Closed-cell insulation is also excellent in insulating against extreme temperatures and moisture.
Benefits of Spray Foam Insulation
Besides ease of insulation, spray foam insulation has other benefits. Below are some examples of its benefits.
It Has High R-Values
R-values refer to the amount of heat flow resistance of the insulation. Spray foam tends to have high R-values, especially the closed-cell version.
It Saves Energy
Because of its high R-value, spray foam insulation could save you on heating and cooling costs.
It Can Reduce Noise
Closed-cell spray foam insulation is fairly effective at noise reduction. However, open-cell insulation also has good sound insulation, but to a lesser degree.
It Can Improve Indoor Air Quality
Because spray foam insulation fills gaps very well, your home will have less unfiltered outside air seepage. That could mean less dust and allergen entering the indoor areas from the outside.
Spray foam roof insulation has excellent conveniences and benefits. However, it can be complex and difficult to install. For example, be careful where and how much spray foam insulation you use in certain places. An experienced professional can prepare your roof and install the spray foam in the right thickness and locations.
