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 comparing polyurethane foam to other insulations, there can be a very noteworthy difference. As an effective air seal, it eliminates the air gaps through which sound travels easiest. Low density polyurethane foam Insulation is superior in controlling mid-range frequencies that include the most common sounds, the the voice of people and stereo music.
Enhanced 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 fibreglassbatts.
Superior Air Barrier Properties

Spray foam insulation is able to hinder air leaks far 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 seldom 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 less gaps for air leaks. This material is also denser than most other insulators, and provides a tight, impenetrable barrier to air infiltration and leaks.

Superiror Energy Efficiency in the Home
Air barrier sealing and a increased under floor insulation material result in greater energy efficiency. This can mean a reduction in the use of heating or cooling systems, this often can result in lower costing energy bills and less carbon emissions. A efficiently insulated under floor 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.

Cost Savings
While polyurethane spray foam insulation is generally more expensive than traditional batts or rigid insulators, it’s real cost may 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 do you 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 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, resulting in a shorter payback period for this project.

Flexibility
Due to the fact that polyurethane foam expands to fill a voic, it offers many benefits to those requiring 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, thinner walls, which means greater flexibility with living space. Finally, because foam insulation is so versatile, home owners have much more flexibility when it comes to framing designs. While rigid insulation requires adequate spacing between studs, polyurethane foam can simply be sprayed into any size opening.
