Why you should use spray foam insulation
Acoustic Insulation Benefits
Low density Polyurethane Foam Insulation has outstanding sound absorption properties and sound transmission properties. When making a comparison of polyurethane foam to other insulations, there often is a very great difference. As an effective air seal, it removes the air gaps through which sound travels theeasiest. Low density polyurethane foam Insulation is far greater in controlling mid-range frequencies that include the most common sounds, the human voice and stereo music.
Increased Insulation
When typical R3.5 fiberglass batts are field installed using traditional methods, the end product is an effective value of only R2.45. Much is lost in inexact fitting, ineffective air barrier and broken vapour barrier. Polyurethane foam howeverdoes not suffer from the installation challenges of traditional fibreglassbatts.
Superior Air Barrier Properties
Spray foam insulation is able to hinder air leaks much more successfully than other types of insulation. Common insulation materials such as rigid foam board or fibreglass batts can budge out of place over a period of time, leaving spots for air to penetrate the home. In addition, these products infrequently fill the entire wall cavity, which means air can usually find a way into the house between the sections of insulation, or at the top or bottom of the wall. Polyurethane spray foam fills the entire area, leaving fewer gaps for air leaks. This material is also more dense than many other insulators, and provides a tight, impenetrable barrier to air infiltration and leaks.
Enhanced Energy Efficiency in the Home
Air barrier sealing and a enhanced under floor insulation material result in increased energy efficiency. This usually means a reduction in the use of heating or cooling systems, this can result in lower costing energy bills and fewer carbon emissions. A efficiently insulated house may even allow you to choose smaller air conditioning and heating systems, which can save both money and space.
Roof Insulation seldom sags or breaks down
Polyurethane Foam insulation adheres to the surrounding substrates as it is sprayed on. This bond holds the foam in place for the life of the building ensuring its effectiveness lasts offering ongoing savings.
Cost Savings
Even though polyurethane spray foam insulation is generally more expensive than common batts or rigid insulators, the foams real cost may actually be much lower. Spray foam serves as insulator, vapor barrier, and moisture barrier, removing the need for most exterior caulking, building paper, and separate vapor barriers. Not only does one save the cost of these materials, but there is extra installation saving. Rather than buying and installing four or even more products, a single application of spray foam can be installed instead. When the cost of spray foam is compared to the total cost of batts and related weatherproofing systems, foam actually is more affordable way of insulating. In addition, the higher R-value of foam equals a greater reduction in energy bills is likely, resulting in a shorter payback period for this project.
Flexibility
Because polyurethane foam expands to fill a space, the foam offers many benefits to people in need of a flexible roof insulation. It is particularly useful when filling oddly-shaped spaces, or those subject to some type of obstruction. Spray foam also allows for smaller, thinner walls, which means more flexibility with living space. Last of all, because foam insulation is so versatile, contractors have far greater flexibility when it comes to framing designs. Although rigid insulation requires adequate spacing between studs, polyurethane foam can simply be sprayed into any size void.
