The Advantages & Disadvantages Of Spray Foam Insulation

Spray foam has been on offer to homeowners for decades, providing insulation in spaces that cannot otherwise be insulated and offering a simple solution that provides excellent returns on your initial investment. However, with so much information available, it can be hard to work your way through the research to come up with a clear view of whether spray foam is the right choice for you.

To help, we've shared 22 advantages and disadvantages of spray foam insulation so that you can feel empowered to make the best choice for your property – read on to find out more.

What Are the Advantages of Spray Foam Insulation?

There are many great advantages of spray foam insulation for both business and domestic property owners. We've shared 13 of the most important advantages for you to consider.

Advantage One – Spray Foam Reduces Your Energy Consumption

As more of us work hard to bring our energy usage down, installing spray foam can help you achieve your goal. Spray foam insulation helps to keep heat in, allowing you to turn off your heating much quicker than ever before. In turn, this reduces your yearly consumption.

Advantage Two – Spray Foam Creates a Strong Thermal Bubble

When it comes to creating an air-tight seal that gives you a thermal bubble, spray foam is unparalleled! Not only does it stop air from moving by more than 20 times but it also creates a thermal layer that keeps you warm when the weather outside is cold and cool when the weather outside is hot.

Advantage Three - Spray Foam Fits in Every Size Space

Many people have small gaps, nooks and spaces that are virtually impossible to reach by hand, meaning that their layer of insulation is not as effective as it can be. Rather than putting up with this, spray foam can be applied to any shape or size space, offering a full layer of protection for the entire property.

Advantage Four – Spray Foam Lowers Your Energy Bills

One of the biggest perks of spray foam is the fact that it reduces your energy consumption, which means that you can look forward to lower bills. When you stop to consider just how expensive modern life is, the idea of reducing your monthly outgoings is an attractive proposition!

Advantage Five – Open-Cell Spray Foam Allows Moisture to Escape

Unlike closed-cell spray foam, open-cell works to let moisture escape from inside the property. This means that you will not have to put up with condensation or even a mould and mildew build-up caused by excess moisture in the air.

Advantage Six – Spray Foam Does Not Hold Water

Many people are told that spray foam holds water which causes damp and other moisture-related issues. In truth, neither open nor closed-cell insulation works in this way. Open-cell allows moisture to escape and closed-cell doesn't. Sadly, sometimes people have closed-cell installed by mistake and the internal levels of moisture then build-up, causing the problems. Stick with open-cell for the best, breathable results.

Advantage Seven – Open-Cell Foam Reduces Moisture, Condensation and Other Problems

If you find that your windows are always covered in condensation then installing open-cell spray foam may help! This type of spray foam encourages moisture to escape, helping you to keep your property clean, safe and problem-free. If you opt to keep things the way they are, you will find that the moisture and condensation that is causing you problems will turn into mould and mildew that can be hazardous to your health.

Advantage Eight – Modern Spray Foam is Kind to the Environment

There is no denying that older versions of spray foam may not have been made from the most environmentally-friendly materials but this is no longer the case. Many open-cell spray foams now use environmentally-friendly products and practices so that you can get the insulation you need without having to compromise your commitment to the globe.

Advantage Nine – Spray Foam Offers a Lengthy Lifespan

When you put insulation into your property, you will want to get the best coverage for the longest amount of time. Spray foam insulation offers the longevity you need, with the ability to last for many decades without requiring ongoing maintenance. When you consider the saving potential for your energy bills, you can be sure that your spray foam will last for a very long time.

Advantage Ten – Spray Foam Protects You From Environmental Nasties

Whether it is constant sneezing due to hay fever or having to dust every day to remove dirt, spray foam is here to help. When you have your spray foam installed you can look forward to cleaner air to breathe and less cleaning required in your home! In fact, spray foam is proven to reduce levels of pollen and dust, helping you to live a healthier and happier life.

Advantage Eleven – Spray Foam Adds Strength to Your Roof, Walls and Floors

Keeping your property in a good, functional condition is vital to your health, happiness and bank balance and spray foam can help. Once spray foam has been installed and cured, it provides extra strength to your property and helps to retain the structural integrity for many years to come. Interestingly, you can look forward to more than a 200% increase in racking strength when you have the right spray foam installed in the right sections of your property.

Advantage Twelve – Spray Foam Can Offer a Sound Barrier

Insulating your property is usually something that is done to improve heat retention and lower energy usage and costs. However, when you use spray foam as your insulator, then you can also look forward to a quieter building. This is because spray foam insulation also acts as a sound barrier, dulling the external noises that may otherwise cause you frustration. If you have spray foam installed in your walls, you can also look forward to a better sound barrier between rooms and less impact from your neighbours' noise if your building is attached.

Advantage Thirteen – Spray Foam Has an Excellent R-Value

An R-value is a measurement of how well your insulation works to resist the flow of heat, helping you to know whether your insulation is going to provide the results you want. Open-cell spray foam has an R-value of 3.5 and up, making it highly effective on its own and a leader when compared to other insulation products. Spray foam also doesn't lose its R-value over time, unlike other insulation materials, meaning that it will provide reliable results for many years without any problems.

Advantage Fourteen – Spray Foam Does Not Require a Vapour Barrier

Before insulation is installed, many types of insulation require a vapour barrier to be laid first, helping to stop moisture from entering the space. However, this can be an expensive process, ramping up the final cost of insulating your property. The good news is that spray foam insulation can adhere to any material and so the need for a vapour barrier is taken away, saving you cash and speeding up the installation of your new insulation.

What Are the Disadvantages of Spray Foam Insulation?

As with all types of insulation, there are some disadvantages to consider. We've found 8 disadvantages of spray foam that you need to be aware of – check them out now.

Disadvantage One – Spray Foam Can Be An Expensive Investment

Many people find that spray foam is an expensive investment and worry that they will not see the appropriate return to make it a viable option. The good news is that, when installed properly by a spray foam specialist, the cost of spray foam should be recouped from a reduction in your energy bills over 2 – 3 years.

Disadvantage Two – The Wrong Spray Foam Can Cause Damage to Your Property

Choosing the right spray foam depends on your property and your needs. The two main types of spray foam insulation are open-cell and closed-cell. For the vast majority of jobs, open-cell will be the best choice. Sadly, if you have closed-cell foam installed then you may find that it causes you more problems that are impossible to resolve as the foam cannot be removed after installation.

Disadvantage Three – You Cannot Install Spray Foam as a DIY Project

If you enjoy DIY projects and want to install your own spray foam insulation then you will be disappointed. Spray foam insulation must be installed by a professional due to the complex health and safety requirements. The good news is that there are many great installation services to choose from, leaving you free to complete a different DIY project instead.

Disadvantage Four – Poorly Installed Spray Foam Can Shrink

Choosing the right installer is always important when it comes to spray foam. Sadly, if you choose a poor installer then you may end up with clumsy coverage that shrinks when the temperatures change. At Countrywide Coatings & Insulation, all of our team have been specially trained in spray foam insulation techniques so that you don't need to worry about shrinkage.

Disadvantage Five – Spray Foam Can Pose a Health Risk

Inhaling spray foam or gases released during installation can have a negative impact on your health. This is why spray foam insulation teams always wear high-quality PPE and expect you to stay away from the installation area until the curing time is up. Once it is cured, spray foam is perfectly safe for you to be near.

Disadvantage Six – Spray Foam Needs to Cure

While spray foam does offer an instant barrier, it must be left for 24 hours to expand and cure before you enter the space that has been insulated. There is no way to speed the curing process up, meaning that you will need to be willing to wait so that the foam isn't damaged and so that your health isn't at risk.

Disadvantage Seven – Spray Foam Installation Takes Time

As with all good things, spray foam takes time to install and you will need to have a day set aside for your installer to complete their work uninterrupted. If you are only having your roof insulated or you have a smaller property then the time will be reduced.

Disadvantage Eight – Closed-Cell Spray Foam Can Cause Water Damage

When it comes to choosing spray foam, if your installer offers you closed-cell spray foam for anything other than a warehouse or agricultural building then you should refuse it as it does not let moisture escape and can be the cause of water damage inside the property.
