How Long Does Blown In Cellulose Insulation Last?

Published on September 20, 2018

When choosing an insulation product, one of the qualities you should take into consideration is the longevity, because, just as with any improvement you make to your home, you want to choose the best solution for your time and money. One option we frequently recommend to our customers is blown in cellulose insulation. Because blown in cellulose insulation lasts well over time, it’s an excellent option for homes big and small.

If blown in cellulose insulation lasts so well, why are there so many options on the market? Why are there so many confusing choices, materials, and installation methods? How long does blown in cellulose insulation REALLY last?

Today, we’re going to give you a primer on blown in cellulose insulation and why we think it may be a great option for your home.

What is Blown In Cellulose Insulation?

There are two popular types of blown in insulation on the market today, made out of one of two materials: cellulose and fibreglass. Cellulose is a material that’s been on the market for decades and has received a lot of attention for being a greener option when it comes to home insulation.

Cellulose insulation is a mix of recycled paper products, such as newspapers, that is treated with a naturally occurring chemical (borate) to be fire and pest resistant. Unlike blown in fibreglass insulation, which has a high embodied energy (the energy needed to create it), blown in cellulose is easier to produce and diverts materials otherwise destined for the landfill.

How is it Done?

If you’re considering adding new insulation anywhere in your home this season, blown in cellulose insulation lasts and is a great option if you need a bit of flexibility. The key to its versatility is in the name - unlike other insulation types that come in batt form, cellulose insulation is blown in. It comes from the manufacturer in small pieces that are simply blown in to place. That makes it an excellent option for walls, small attics, or other spaces where traditional insulations would be much more expensive or labour intensive to install.

Blown in cellulose insulation can be installed in new or old structures and on top of existing insulation too. When spaces are under insulated, blown in cellulose insulation can simply top up existing materials and add increased R Values and longevity to your home.

Blown in cellulose insulation also adds an advantage when it comes to time and labour - while doing it right takes skill, blown in cellulose insulation can be installed by small teams and with minimal disruption to your home and life. This is a huge difference from the old days, when huge teams would need a week or more to install your insulation and cause significant disruption to your life. With blown in cellulose insulation, a day or two is all we usually need to perform a high-quality installation.

What Are the Benefits and Advantages of Blown in Cellulose Insulation?

Installing new insulation anywhere in your home has a great number of advantages and benefits:

  • It helps to reduce your energy consumption and lower monthly heating and cooling costs by helping prevent heat leakage.
  • It helps keep your indoor temperature level stable all year round by providing better thermal coverage and keeping your conditioned air where it belongs - inside.
  • It reduces the wear and tear that overuse causes to your HVAC system. When air constantly leaks from your home, your furnace needs to work twice as hard - which means twice as many repairs.
  • It promotes better indoor air quality by helping to reduce outside pollutants.

How Long Does it Last?

How long blown in cellulose insulation lasts is the 60 million dollar question. All types of insulation degrade over time, and insulation eventually loses its ability to help regulate the temperature of your home and must be replaced.

How long blown in cellulose insulation lasts is thus dependent on a number of different factors, such as:

  • Water damage: Leaks in your roof or from pipes can degrade cellulose insulation in time.
  • Pests: Insects, mammals and birds can all cause damage to insulation.
  • Mold growth: While the borate treatment given to cellulose insulation helps to make it mold resistant, 90% of insulation materials won’t hold out under ideal mold growth conditions.
  • Damage: Work in your attic can shift and damage your insulation, causing it to be less effective.

Generally, when answering the question of how well blown in cellulose insulation lasts,  estimates will vary depending on the age of your home, but the International Association of Certified Home Inspectors states that blown in cellulose insulation could last up to 100 years!
