Spray Foam Insulation Cost: Everything You Need to Know

Polyurethane is a plastic material which exists in various forms. It can be tailored to be either rigid or flexible. Tate’s Coating Services focuses on using polyurethane foams and elastomers. This includes the mixing of two chemicals and then the foam or elastomer can be spray applied or injected to suit many needs. For further information – http://www.polyurethanes.org/en/what-is-it

At Tate’s Coating Services our polyurethane foam insulation systems are spray-applied using two-component products. The A-side component is an isocyanate and the B-side component is a resin. It is not a wet application, so no water is used. During the application, a chemical reaction takes place between the two components, creating a bond to the substrate as it foams up. It dries, cures and hardens within 3 to 5 seconds depending on the materials used and the job scope. This product should always be installed by an experienced applicator.

Polyurethane foam insulates and air seals in one step, which traditional insulating products do not do. Traditional insulations can also leave gaps around trusses, light fixtures, and any other building details which compromises performance. Polyurethane on the other hand fits perfectly around all detailing to provide a complete air seal.  The performance of Spray Foam as an insulation does not diminish over time so energy savings are constant and ongoing for the lifetime of the building.

Most of the damaging moisture within a building envelope is the result of air movement through the cavities. When warm air meets a cold surface within a cavity, it condenses and if not found in time, it can lead to mould and rot. Polyurethane foam creates continuously insulated walls and ceilings – exactly the leak-free building environment that is needed to minimise the potential for moisture, condensation and mould.

Yes. Polyurethane foam can also help with:

• Noise reduction – Thanks to the sound-dampening qualities of polyurethane foam insulation, problems and annoyances related to “thin walls” can easily and effectively reduced.
• Access and repair – Unlike traditional insulation types, portions of an area can be repaired if damaged rather than the entire area requiring re-spraying.

Yes, polyurethane foam has been accredited to meet building standards. At Tate’s Coating Services, we have information available on request stating the fire properties of polyurethane foams we use, as well as any other relevant information on the product requested.

Polyurethane spray foam insulation will last up to the lifetime of your home, generally 30 to 50 years. Unlike other materials and traditional insulation types, polyurethane foam does not sag or deteriorate over time. It may change colour during its lifetime due to UV light however if the foam is protected it will last for decades.

Open-cell foam is a soft flexible, water-blown foam with a high expansion. Once sprayed, low-density open-cell foam can be easily trimmed. It also permits bi-directional drying and has low ozone depletion potential (ODP) making it an environmentally friendly and sustainable insulation option.

Closed-cell foam is a hard rigid foam with more controlled expansion and typically a little more difficult to trim. Closed-cell provides a higher R-value per 25mm, meaning it has greater insulating power. Closed-cell foam can add structural integrity to a building while also providing an effective barrier to vapour and bulk water.

Both open-cell and closed-cell foam have different advantages so it’s not as simple as choosing “one or the other”. The best foam to be used in each situation is dependent on several factors such as design objectives, application, available space, needed R-value and costs.

Return on investment varies from region to region. However typically, homeowners who upgrade from traditional insulating products to polyurethane foam experience a 30 to 50% reduction in energy costs.

Polyurethane foam insulation enables efficient heating and cooling of a building which in turn reduces greenhouse gas emissions. 100% water-blown options such as open-cell polyurethane spray foam offer the lowest global warming potential and ozone depletion potential (ODP). Polyurethane also improves indoor air quality with no off-gassing.

Polyurethane foam insulation can help by keeping insects out as it seals all the cracks into your home. It does not repel or keep burrowing insects, such as termites, from tunnelling to get to food sources; however, the foam is not a food source itself. In heavily infested areas insects can tunnel and use the foam as a shelter. In these cases, standard pest control methods should be followed.

No

During the application of polyurethane spray foam, the chemical reaction does give off a slight odour however given ventilation, this dissipates in a short time. Once the foam has finished reacting it becomes inert and no off-gassing, odours or smells are present.

No. Polyurethane insulation is NOT urea-formaldehyde foam insulation. There is no added formaldehyde in the polyurethane foam insulation products used today.

Spray foam insulation can last up to 80 years when applied correctly. At Tate’s Coating Services, we use only the highest quality, Australian made, spray foam insulation products to ensure your insulation lasts for its expected lifespan and even longer.

Insulation R values

How well an insulation product resists heat flow is know as its R value. The higher the R value, the higher the insulating performance. The appropriate degree of insulation depends on your climate, building construction type, and whether auxiliary heating and/or cooling is to be used.

Material R values refer to the insulating value of the product alone. The NCC and BASIX (in New South Wales) set out minimum requirements for the R values of materials used in the construction of buildings. It is generally advisable to exceed these for greater comfort and energy savings.

Total R value

‘Total R value’ describes the total resistance to heat flow provided by a roof and ceiling assembly, a wall or a floor. Each of the material components has its own heat resistance (R value), and the total R value is calculated by adding the R value of each component, including the insulation.

Total R values are the best indicator of performance because they show how insulation performs within the building envelope. Total R values are used when calculating energy ratings to measure thermal efficiency.

Total R values for roofs, ceilings and floors that use reflective insulation are expressed as up and down values, depending on the direction of heat flows through the product:

• ‘Up’ R values describe resistance to heat flow in an upwards direction (sometimes known as ‘winter’ R values).
• ‘Down’ R values describe resistance to heat flow in a downwards direction (sometimes known as ‘summer’ R values).

Both up and down R values should be considered when installing roof, ceiling and floor insulation. Total R values for walls are expressed as a single figure, without ‘up’ and ‘down’ distinctions.

Many factors can reduce the total R value, including thermal bridging, compression of bulk insulation, dust settling on reflective insulation and the lack of a suitable air gap for reflective surfaces. Careful installation according to specifications is needed to ensure your insulation performs as it should.

Note

R values as used in Australia, New Zealand and Europe are metric and are different from R values used in the United States. American products and publications quote R values that will appear much higher than the values seen in Australian products and discussed in Your Home. There is no simple conversion factor between American and Australian units, so it is best not to use those values – seek out the metric values instead.

Spray foam insulation cost in Australia can vary due to the variety of climates. For areas that have hotter summer and colder winters, a higher R-factor is recommended. This will provide a higher level of insulation and will help to reduce the need for air conditioning and heating.

The average cost of spray foam insulation has been figured on a combination of open cell and closed cell insulation installations for a 2200 square foot home and is around $1800 to $5000.

There are kits on the market for DIYers to spray their own foam insulation. However, without the experience of a qualified installer, many areas of application technique can be overlooked. Additionally, you could be at risk of uneven R-value and hidden air pockets.

Spray foam insulation is on average more expensive than fibreglass insulation but is more effective at insulating a home.  Your return on investment with Spray Foam Insulation is greater over time.

As the name implies, spray insulation is sprayed into a wall or ceiling cavity rather than manually installed. The liquid polyurethane quickly expands and hardens when it is sprayed, changing into a thick layer of foam insulation, resembling honeycomb. Depending on the solution, the foam insulation can be one of two types:

1. Open-cell foam has more air locked inside the foam barrier.
2. Closed-cell foam is denser and makes a room more airtight than other insulating materials.

The “R-value” of insulation is a measurement of its resistance (“R”) to heat transfer. Spray foam insulation can have an R-value of up to 6 per 25mm, which is higher than any other type of insulation. The major reason for this is because it creates a tighter seal than batts or loose insulation, which often has gaps that allow heat to be transferred through walls.

There are a few disadvantages to spray insulation you should consider before choosing it over batts or loose-fill insulation:

1. Polyurethane degrades when exposed to UV light. It should only be used in areas where it is not exposed to sunlight.
2. It needs to be sprayed before gyprock/drywall is installed. If you are installing insulation in un-insulated wall cavities, consider using a loose-fill wall insulation service.
3. During the spraying process, spray insulation releases harmful gasses. Because of this, it is not suitable for DIY installation.
4. All foams are flammable, so you may need to install an “ignition barrier” between the foam and a heat source such as a water heater or fireplace. Polyurethane foam does not burst into flames or continue to burn when the heat source is removed and complies with Australian fire standards.

Keeping these drawbacks in mind, spray insulation is still an excellent choice for new wall, under floor and ceiling insulation. If it is professionally installed, it provides long-lasting, superior insulation.

Most building inspectors will look at insulation when in their reports so inadequate insulation will be made apparent to potential buyers. As a rough guide, good insulation can increase the value of a home by 5% or so.

Yes, spray insulation is very efficient when used in your roof.

While there are many benefits to spray foam insulation, there are also some potential downsides to consider.

One downside is the cost. Spray foam insulation can be more expensive than traditional insulation methods, such as fiberglass batts or blown-in cellulose. However, the energy savings and other benefits will ultimately make up for the initial cost.

Another downside is that spray foam insulation must be installed by a professional, as it requires specialized equipment and expertise. Improper installation can lead to issues such as incomplete coverage or moisture problems.

Spray foam insulation is one of the best insulation materials available. Its high R-value performance, meaning it has excellent insulating properties, will help to reduce energy costs effectively and consistently. Spray foam insulation can also help to reduce air leakage, which can lead to a more comfortable and consistent indoor temperature. However, it’s important to note that the effectiveness of spray foam insulation, like other insulating products, depends on factors such as installation quality, building design, and climate. It’s important to consult with a professional insulation contractor to determine the best type of insulation for your specific needs.

Yes, spray foam insulation is a popular insulation solution in Australia. It is commonly used in new construction and retrofit projects for residential, commercial, and industrial buildings. However, it is important to ensure that the product used is compliant with Australian standards and regulations. At Tate’s Coating Services, we only use high-quality, Australian-made spray foam insulation products that are compliant with all relevant standards and regulations.

Where should you not use spray foam insulation?

There are certain areas or situations where spray foam insulation may not be suitable or recommended. Here are a few examples:

1. Unvented attics: Unvented attics, or attics with no ventilation, require a different type of insulation to avoid moisture build up. In this case, spray foam insulation may not be recommended.
2. Wet or damp areas: Spray foam insulation should not be installed in areas that are wet or damp, as it can trap moisture and potentially lead to mold growth.
3. Areas with existing insulation: If there is already insulation in an area, it may not be cost-effective or necessary to add spray foam insulation on top of it.
4. Areas with potential for movement: Spray foam insulation is a rigid material and may crack or break if there is movement in the area where it is installed.

It’s important to consult with a professional insulation contractor to determine if spray foam insulation is the best option for your specific situation.

While mold growth behind spray foam insulation is relatively rare, it is still possible if the insulation is not installed properly. If there is any moisture present in the wall cavity, the spray foam insulation can trap the moisture and prevent it from evaporating, which can create the ideal conditions for mold growth. To prevent this from happening, it’s important to ensure that any moisture issues are addressed before installing spray foam insulation, and to have the insulation installed by a qualified professional who knows how to properly apply and cure the insulation to prevent any moisture from becoming trapped behind it. Additionally, it’s a good idea to monitor the area behind the spray foam insulation for any signs of moisture or mold growth, and to have it inspected periodically by a professional to ensure that it remains in good condition.

There is no evidence to suggest that spray foam insulation decreases home value. In fact, many homeowners and real estate agents consider spray foam insulation to be an added value to your asset and a selling point for a property. Spray foam insulation will improve energy efficiency, indoor comfort, and air quality, all of which can be attractive features for potential buyers. Additionally, if the spray foam insulation has been properly installed by a reputable contractor, it will be a long-lasting and durable solution, which can also add value to a property.

When applied correctly, spray foam insulation can last a long time, with an expected lifespan of up to 80 years. However, the actual lifespan of the insulation may vary depending on various factors, including the quality of the installation, the conditions in which the insulation is exposed to, and the type of foam used. It is important to properly maintain and monitor the insulation to ensure it lasts as long as possible.

The length of time you should stay out of your house after spray foam insulation installation can vary depending on the specific product used, as well as the conditions of the installation. In general, manufacturers recommend that homeowners stay out of their homes for a period of 24-48 hours after installation to allow the foam to fully cure and any fumes to dissipate. It’s important to follow the specific instructions provided by your installer and the manufacturer to ensure safe and effective installation of the spray foam insulation.

Polyurethanes are polymers – chains of structures made from repeating units bonded together called monomers. While there are thousands of natural and man-made polymers,

1 polyurethanes are a type of polymer formed by reacting a polyol with diisocyanate or polymeric isocyanate.

2. Due to the range of possible combinations, polyurethanes are some of the most versatile plastics – able to take on multiple forms including foams, coatings, sealants, adhesives and elastomers.
3. They surround us in our daily lives – from the mattresses we sleep on, to the shoes we wear, to the insulation in our homes and the paint that coats our built environment.

Spray foam insulation can significantly improve the energy efficiency of residential buildings in Australia by providing an airtight seal that prevents air leaks and helps maintain a consistent temperature indoors. This means that heating and cooling systems don’t have to work as hard to maintain a comfortable temperature which reduces energy usage and ultimately lowers energy bills. In addition, polyurethane spray foam insulation has a high R-value, which is a measure of its ability to resist heat flow. This means that it can provide better insulation than other traditional forms of insulation like fiberglass and cellulose. Spray foam insulation also has the potential to reduce greenhouse gas emissions by improving energy efficiency and reducing energy consumption.
