In this blog post we are going to look at the differences between spray foam insulation and traditional fibreglass. We’ll be investigating the benefits of SPF and asking the important questions, which we hope will allow you to make an informed decision when it comes to the energy efficiency and insulation of your home or business premises.
As experts in the spray foam insulation industry, we are always happy to answer any questions potential clients may have. It is with this in mind that we have broken this blog post into sections, each one addressing a frequently asked question about spray foam or fibreglass insulation.
Which insulation product is more airtight?
Both spray foam and fibreglass have good insulation properties, however fibreglass does not provide you with an airtight seal and is laid only at ceiling level. Spray foam insulation will expand to fit any space, no matter how small or awkward to reach and can be applied in a way that will optimise the space in your attic.
I would like to use insulation in a living space in my home, what would you recommend?
Whilst fibreglass insulation is used most commonly in attic spaces, it is not suitable for use in any area that you or your family will be using regularly. Spray foam insulation is safe to use in all areas of the home, occupied or not.
I want to ensure that the insulation in my home has a long lifetime, which option lasts longer?
Spray foam insulation will last for your lifetime and possibly even longer, one of the great benefits of spray foam is that is can last and maintain it’s efficiency for over 80 years. On the other hand, traditional fibreglass insulation has a lifetime of just 10-20 years and this is very dependant on it remaining dry. As time goes on, fibreglass insulation will degrade and loose it’s efficiency.
Will either product help to provide a sound barrier in my home?
Yes, Spray foam insulation will act as a sound barrier in any room in the home and will greatly improve your quality of life if you are living in an area that has heavy traffic. Sprayed on internal walls in your home, it will also improve internal noise levels between rooms. Fibreglass insulation does not provide any sound dampening qualities.
Do I need to be aware of any irritations from either product?
Spray foam insulation does not produce any irritants, no fibres, vapours or particles. Traditional fibreglass can however irritate the respiratory system through the release of fibres and particles if proper care is not taken during installation.
To get the very most from the insulation in your home, we would highly recommend the application of spray foam insulation. This modern material has many benefits over traditional fibreglass insulation:
- Does not degrade or deteriorate in its efficiency over time.
- Can be applied in hard to reach and small awkward areas, which would normally not be covered by fibreglass insulation.
- Available in closed cell and open cell application, providing you with further options.
- Breathable material, allowing fresh air to circulate without impeding on the energy efficiency of your home.
- Provides structural benefits.
- Saves space in your attic.
- Clean, safe and quick application process, can be applied with little or no disruption to the daily running of your home or business.
- Pest proof – because spray foam insulation hardens once applied, it does not allow pests to nest in the material.
- Once off investment providing optimum insulation for over 80 years.
