Cellulose Insulation vs. Fibreglass Insulation

As you are getting ready for winter, you are probably thinking it would be worthwhile to get your attic insulation topped off. Adding additional insulation in your attic is a great way to help conserve energy and lower your heating costs.

Two of the most common types of insulation people use to top off their attics are cellulose insulation and fibreglass insulation. How do you decide which one is right for your home? Here at Logik Roofing, we are pleased to offer the following information that highlights the pros and cons of both types.

Cellulose Insulation Pros

  • Friendly for the Environment – Cellulose insulation is made from recycled materials and puts post-consumed paper-based products to good use insulating your home instead of in a landfill.
  • Superior Performance – Cellulose insulation has a much high R-rating value per square inch than fibreglass insulation. The “air tightness” of cellulose can be as much as thirty percent higher.
  • Nonflammable – Cellulose insulation is treated to be flame resistant, so it is safe to use in your home, even though it is made from recycled paper products.
  • Resistant to Settling – As cellulose insulation is blown into your attack, it does not need to be compacted or pushed down as much as fibreglass does. Once finished, it does not settle and sink like fibreglass can.
  • Fewer Health Risks – Since cellulose is made from paper-based products, there are less health risks compared to fibreglass insulation.
  • Easier to Fill in Gaps and Small Openings –Small gaps and openings in between support structures can be filled in eliminating unwanted “air pockets.”

Cellulose Insulation Cons

  • Can Be Messy – Since it is loose insulation, it can be a bit messier than fibreglass. However, when it is installed by a professional, they will clean up afterwards.
  • Can Absorb Water – If you have a leaky roof or improperly vented attic, water and moisture could ruin and damage cellulose insulation. Luckily for you, Logik Roofing can install a new roof to resolve leaky roof problems, as well as ensure your attic is vented correctly.

Fibreglass Insulation Pros

  • Water Resistant – Fibreglass is water resistant, but it can still get ruined from exposure to water and moisture.
  • Less Messier – Since fibreglass insulation comes in rolls, there is nothing loose. But you do have to cut the rolls into the desired lengths.

Fibreglass Insulation Cons

  • Costs More than Cellulose – You could pay two or three times or more to top off your attic to the desired R-value level.
  • Settles over Time – Fibreglass will settle which causes the effectiveness and R-value rating to decrease.
  • Higher Health Risks – Fibreglass poses several health risks including allergic reactions, itchy skin, watery eyes, irritation to the throat and nose, rashes, respiratory problems in asthma sufferers, and more.
  • Takes Longer to Install – The fibreglass insulation has to be unrolled, and then cut to size to be installed correctly. In addition, it may also have to be secured in place.

As you can see, cellulose insulation has several advantages over fibreglass. To learn more about cellulose insulation or to request a quote to get your attic topped off, please feel free to contact Logik Roofing at 905.424.7469 today!
