Acoustic Insulation Benefits
Low density Polyurethane Foam Insulation has excellent 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 gets rid of the air gaps through which sound travels easiest. Low density polyurethane foam Insulation is far greater in controlling mid-range frequencies that include the most common sounds, the the voice of people and stereo music.
Enhanced Insulation

When typical R3.5 fiberglass batts are field installed using traditional methods, the end result is an effective value of only R2.45. Much is lost in inexact fit, ineffective air barrier and broken vapour barrier. Polyurethane foam does not suffer from the same installation challenges of traditional fibreglassbatts.
Greater Air Barrier Properties

Spray foam insulation is able to prevent air leaks far more effectively than other types of insulation. Traditional insulation materials for example rigid foam board or fibreglass batts may slip out of place over a period of time, leaving areas for air to penetrate the house. In addition, these products rarely fill the entire roof cavity, which means air can usually find a way into the home between the sections of insulation, or at the top or bottom of the wall. Polyurethane spray foam fills the entire space, leaving less 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.

Superiror Energy Efficiency in the Home
Air barrier sealing and a superior under floor insulation material result in greater energy efficiency. This usually means a reduction in the use of heating or cooling systems, which can result in lower costing energy bills and less carbon emissions. A well insulated under floor may even allow you to choose smaller air conditioning and heating systems, which can save both money and space.

Roof Insulation never sags or breaks down
Polyurethane Foam insulation bonds 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.

Costs
Even though polyurethane spray foam insulation is typically more expensive than typical batts or rigid insulators, the foams true cost may be far less. Spray foam serves as insulator, vapor barrier, and moisture barrier, getting rid of the need for most exterior caulking, building paper, and separate vapor barriers. Not only do you save the cost of these materials, but there is an associated 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 appears to be the more affordable way of insulating. In addition, the higher R-value of foam means a greater reduction in energy bills is likely, this results in a shorter payback period for this project.

Flexibility
Because polyurethane foam expands to fill a voic, the foam offers many benefits to those in need of a flexible roof insulation. It is at it’s most useful when filling oddly-shaped spaces, or areas subject to some type of obstruction. Spray foam allows for smaller, skinnier walls, which means greater flexibility with living space. Last of all, because foam insulation is so versatile, contractors have much more flexibility when it comes to framing designs. While rigid insulation requires adequate spacing between studs, polyurethane foam can easily be sprayed into any size void.
