Expanding Foam Insulation Cost and Benefits

benefits of foam insulation

As compared to other forms of insulation, expanding foam is the most expensive. However, the cost is worth it because expanding foam insulation is the most effective form of insulation. When you use this form of insulation, you are assured of warmth in the house during winter and coolness during summer. There is no time that external temperatures will have a noticeable effect on the internal temperatures of your house when you use expanding foam.

How to Use Expanding Foam 

Expanding foam requires professionalism during installation. Since you do not know how to use expanding foam, it is best that you consult the services of a professional because only professionals know the right ways to install expanding foam insulating material. Expanding foam costs much and so it would be unwise to waste it by not installing it well.

The Cost of Spray Foam Insulation

On average, the cost of expanding foam insulation ranges between $1.50-$4.90. that is costly and many may not opt for this insulation. Nevertheless, I would strongly advise you to embrace the cost because it will be worth it. The effectiveness of expanding foam insulation is so perfect that it goes beyond thermal regulation to water resistance, defense against moisture, and better air circulation. 

You will also save on bills and so after a few years you will have recovered your installation cost and you will have many years ahead to enjoy the effectiveness of expanding foam insulation. When you do the math, you will realize that it pays great to work installing your house using the best expanding foam insulation UK has to offer.

How to Remove Expanding Foam

Expanding foam is normally removed using acetone. Acetone dissolves uncured polyurethane foam and therefore it’s commonly used to remove expanding foam before it cures. Acetone-based nail polish can also used to remove the uncured foam. However, this product cannot remove cured expanding foam. When it cures, expanding foam is best removed by sanding or scraping it off. Professional expanding foam installers are experts on how to remove expanding foam and so it is best if you seek their services whenever you need to have expanding foam removed.

Reasons why the High Cost of Expanding Foam is worth it

Expanding foam has many other advantages apart from remaining heat within a house and protecting the occupants of the house from external temperatures. Because of its nature, expanding acts as a perfect insulator. This foam keeps sound from outside from getting into your house which protects you and your family from external noises. Expanding foam sound insulation also adds to your privacy because the sound in your house is not heard outside. 

That means that you crank the volume high, play with your family, and even shout without the worry of disturbing your neighbors or having them listen to what is happening in your house.

Comparing the Cost and the Benefits of Expanding Foam Insulation

Expanding foam insulation may be costly to buy and install, but as you already know by now, its benefits surpass the pinch of its cost. This is because apart from you having warmer winters and cooler summers, you will have sound proofing capabilities, better air circulation, and very many years of comfort all thanks to expanding foam insulation.

Improve Interior Air Quality with Foam Insulation

Insulation in the roof and walls has ability to reduce heating and cooling losses in following ways:

  1. But don’t forget that convection is another source of heat transfer when air moves between two spaces. Minimizing or controlling losses via convection is desirable but requires more consideration. Adequate outside air is necessary for breathing, and sufficient air transfer is required to ventilate other gases and odors from interior spaces.
  2. Most homes are so leaky that there is plenty of opportunity for air to intrude and be enough for the occupants. However, as structures become more air-tight and interior materials become more synthetic, there is the possibility that the indoor air quality is compromised.
  3. Controlling infiltration of outside air is important. Not only is uncontrolled air infiltration wasteful of energy it can also carry outside pollutants such as fumes and dust. Inadequate exhaust of indoor pollutants can cause allergies, respiratory distress and ‘sick building syndrome.
  4. Expanding foam insulation applied to walls and roof voids fills small spaces and gaps that allow air to flow between the interior of a home and the outside environment. Eliminating these gaps prevents air convection from carrying heat between the interior and exterior of a home, which results in lowering the expense of heating or cooling a space.


Minimizing air from entering from the outside into the house means that expanding foam insulation can improve the quality of air inside your house. With proper permeable filters and especially electrostatic filters installed with your air-handler, circulating inside air can be controlled and cleaned of allergens, particulates and pollutants within a building’s interior. By using expanding foam insulation to reduce infiltration of outside contaminates, the inside air is a higher quality. This may be an even more important consideration if a resident suffers from allergies or respiratory conditions.
