A Quick Look at the Advantages of Cellulose Insulation

Insulation in Attic Floor

When you're considering insulating either a new structure or upgrading the insulation in an older structure, have you really considered all of your options? Though it's fairly easy to go with what you've already used in the past, you may find that other options provide you with better outcomes overall. In this post, we'll give you a brief overview of cellulose insulation and some of the many benefits you can discover for it in your projects.

Cellulose insulation is made from paper products, most of which have been recycled, that have been then ground up into the insulation. It's then blown into a wall system or attic using a special piece of equipment commonly found at building supply stores, allowing the small pieces of insulation to create a more densely-packed blanket than fiberglass batts, rolls or blankets will often allow.

It's treated with a number of compounds that are not harmful to people to reduce the risk of problems with fire, mold and insect damage. Typically, this includes a boric acid compound called borate, which provides both fire and insect repelling properties to the insulation. Other compounds may be added to reduce potential problems from mold or mildew should the insulation get wet.

If you're considering renovations down the road or have concerns about water damage, it's very easy to remove only the cellulose that is in question and replace it after repairs have been made. Fiberglass, on the other hand, must be removed and another piece of the same R-value, width, depth and facing material will need to be used to replace it if it is damaged.

Because it is typically blown into a cavity, it does a much better job of fitting around obstructions such as outlet boxes and pipes that pass through a wall or attic system. It also tends to be much more dense than fiberglass in the wall system, which means it also does a much better job of slowing down air flow from one side of a wall or attic to the other, reducing cold drafts that can result from poor fiberglass installation.

Blown in Fiber Insulation

In attics, it can be added to down the road, allowing you to improve your energy efficiency later on. It can even be blown in on top of existing fiberglass batts to improve your attic's overall R-value and energy efficiency. Though both cellulose and fiberglass can be displaced if there are strong drafts coming across your attic, cellulose is fairly easy to put back in place as compared to a fiberglass batt that has been pulled apart by the wind.

It's considered to be a more green material than fiberglass. Though both products use recycled material in production, cellulose typically has in excess of 75% recycled material as compared to fiberglass' 30%. While cellulose is simply ground up and treated, glass must be heated to a few thousand degrees to be produced, requiring significantly higher energy inputs. This makes cellulose a clear winner for LEED certification.
