Why you should use spray foam insulation
Acoustic Insulation Benefits
Low density Polyurethane Foam Insulation has anexcellent sound absorption properties and sound transmission properties. When making a comparison of polyurethane foam to other insulations, there can be a very noteworthy difference. As an effective air seal, it removes 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 voice of a human and loudstereo music.
Increased Insulation
When traditional 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 fitting, ineffective air barrier and broken vapour barrier. Polyurethane foam does not suffer from the installation challenges of traditional woolbatts.
Enhanced Air Barrier Properties
Spray foam insulation is able to hinder air leaks far more efficiently than other types of insulation. Typical insulation materials for example rigid foam board or fibreglass batts can slip out of place over a period of time, leaving places for air to penetrate the home. Additionally, these materials hardly ever fill the entire ceiling 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 far less gaps for air leaks. This material is also denser than many other insulators, and provides a tight, impenetrable barrier to air infiltration and leaks.
Increased Energy Efficiency in the Home
Air barrier sealing and a superior under floor insulation material result in greater energy efficiency. This often means a reduction in the use of heating or cooling systems, which can result in lower costing energy bills and far less carbon emissions. A well insulated home may even allow you to opt for smaller air conditioning and heating systems, which can save both money and space.
Roof Insulation never 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.
Costs
While polyurethane spray foam insulation is typically more expensive than traditional batts or rigid insulators, it’s true cost may actually be much lower. Spray foam acts as insulator, vapor barrier, and moisture barrier, eliminating the need for exterior caulking, building paper, and separate vapor barriers. Not only does the home owner 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 utilised instead. When the cost of spray foam is compared to the total cost of batts and related weatherproofing systems, foam actually is more affordable option. In addition, the higher R-value of foam equals 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 space, the foam offers many benefits to those requiring a flexible roof insulation. It is at it’s most useful when filling oddly-shaped spaces, or those subject to some type of obstruction. Spray foam allows for smaller, skinnier walls, which means more flexibility with living space. Finally, because foam insulation is so versatile, home owners 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.
