Cons of Blown-In Attic Insulation: Poor installation can lead to uneven coverage, material waste, and even structural issues like sagging ceilings. Hiring a skilled installer is crucial to getting the most out of this insulation type.
Batt insulation is more effective over the life of the building. It is true that blown-in insulation is considered to be more effective as a thermal barrier, however, this effectiveness is only temporary and will not last for the life of the building.
Blown-in insulation, available in fiberglass and cellulose varieties, generally lasts 20 to 30 years. Fiberglass tends to be the more durable option, while cellulose is more sensitive to humidity, which can affect its longevity in certain climates.
It's also fire-resistant. Rodents generally are not drawn to cellulose insulation, either.
When blown-in insulation settles, your attic loses insulation performance. Settling compromises the R-value of your insulation.

While cellulose insulation itself is treated to be mold-resistant, the surrounding structure may not be. Understanding how and why mold is likely to occur can help you prevent serious structural damage. Given these risks, swift action is imperative if you suspect your cellulose insulation has become wet.
Wet insulation in a wall will migrate to the bottom soaking the wallboard and framing materials. Wetness (existing even just for a few days) will not only reduce the insulating quality of the insulation, but it might not dry soon enough to prevent mold and wood decay from forming.
Insulation is more than just material. It's about creating a healthy, efficient, and comfortable living space. Removing old insulation might seem like an extra step, but it's a leap toward better air quality, increased efficiency, and peace of mind. So, when you're looking to upgrade, don't just add—replace.
Fiberglass batt is considered to be the best insulation for attics. Compared to other insulation materials, it is the cheapest and easiest to install. Fiberglass batt is also incredibly energy efficient, as it helps to slow the spread of hot and cold air.
Blown-In Cellulose Particles Are Paper.
Unlike glass fibers, cellulose isn't dangerous to breathe. However, it can irritate your lungs. If you have pre-existing allergies, the dust of cellulose insulation can be obnoxious.
There are other types of insulation, but these are the most common. The best non-toxic insulation is either mineral wool or foam insulation inserts.
Look for insulation blower rental equipment in The Home Depot Tool Rental Center to help keep your home cool in the summer and warm in the winter. Heating and cooling costs are the biggest portion of utility bills for the average homeowner.
Blown-in insulation offers several advantages over other types of insulation. It is highly efficient and can significantly reduce energy bills. Additionally, because the insulation can be blown into difficult-to-reach spaces, it can provide more comprehensive coverage than other types of insulation.
One of the most effective methods for combatting mice infestations is homes insulated with spray foam. Homes insulated with spray foam are renowned for their exceptional airtightness and insulation properties.
Vacuum insulated panels have the highest R-value, approximately R-45 (in U.S. units) per inch; aerogel has the next highest R-value (about R-10 to R-30 per inch), followed by polyurethane (PUR) and phenolic foam insulations with R-7 per inch.
You can keep rodents and bugs out of your home through duct sealing. Some of the things needed for effective duct sealing include screwdrivers (for opening vent entries), safety gloves, traps, baits, fine wire mesh, torch, soap and plastic bags for disposing off the dead rodents/ bugs.
Cellulose insulation is heavy, and compacts any underlying insulation. Because cellulose insulation is paper, it absorbs moisture when it rains, and in areas of high humidity. Cellulose insulation degrades over time and has to be replaced. Cellulose insulation promotes the growth of mold & mildew in your attic.
In winter, temporarily open windows just a little to allow warm moist air to leave the home and also allow cold, dry air to come in. For a short-term fix you can put a dehumidifier in your attic, but understand that you may be emptying it multiple times a day.
The formaldehyde levels from the test results (12.7 µg/m3) are at 20% of those allowed by GREENGUARD (61.4 µg/m3). It is good to know that blown-in-cellulose insulation is indeed a low-emitting product!
