Insulation is a key constituent for home heating and cooling efficiency , which is why it is commonly installed in the paries and bean of most newfangled home and regularly replace in existing homes . Blown - in insulation is a pop selection because it fill up the cranny and gaps , reducing drafts and improving rest home energy efficiency , though some DIYers may add together loose fill insularity toincrease the R - value of the existing insulationor deal with on an irregular basis shape sphere of the dwelling house .
Cellulose attic insulant is one of the most frequently install type of blown - in insularity , though you’re able to also install cellulose insulating material in walls to slow the transfer of heat into and out of the home . The radius - value of cellulose insulating material tend to be higher than comparable materials , and it ’s often less expensive as well . Because of this , cellulose insularism has been develop in popularity . expend this informative guide to learn more about cellulose insulation and the benefit it can bestow to your home .

1. Cellulose insulation is primarily made of recycled paper products.
One of the best feature of cellulose insulant is that it ’s agreen materialthat is made mainly from 80 to 85 percentage recycled paper Cartesian product , agree to theU.S. Department of Energy . Most of this per centum is made up of erstwhile newsprint and similar paper material that are first reduced to little piece before being fiberized to create one of thebest attic insulationoptions available .
To facilitate mitigate cellulose insulation danger , the fiberized cloth is then treated with fire - resistant and insect - resistant mineral borate , which can sometimes be blended with ammonium sulphate for a more affordable ruined mathematical product . This compounding creates an vim - efficient insulation that can be blown into attics and wall for quality insulation that can last for decades .
2. Cellulose insulation is typically used in attics and walls of new and existing homes.
When you are considering differenttypes of insulationfor the nursing home , it ’s important to know where each case of insulation is well suited for use . In most cases , cellulose insularism is instal in the attics and wall of new home , though it can also be blown into finished wall without needing to remove the dry wall , making it a riotous , effective way to add to existing insulation or to replace sometime insulation stuff .
The main reason for instal cellulose insulation in these areas of the home is because of the affordablecellulose insulant cost , high R - value , and various detachment methods that make it prosperous for professionals to install . to boot , the fervor - resistant and pest - tolerant nature of the stuff helps to protect the home and deter undesirable invaders .
3. Cellulose insulation is most commonly installed by being blown in.
Cellulose insulation can be installed using the loose - filling method in which the installer or DIYer simply blows the insularity into an open bonce using a swash political machine . This method is effective for degraded and easy installment in candid areas , but the promiscuous - filling cellulose does not have the same R - note value as dense - fill cellulose .
For dense - fill installing you necessitate to practice a specialized cellulose insulating material electric fan with a smaller hosepipe that lead in a much higher density of insulation with minimal air pockets . This character ofblown - in insulationis normally used to fill wall cavity and enclose finished space , though it can also be instal behind net that is stapled over building cavities .
likewise , some installers may utilise the damp spray method acting to install cellulose insulation by add up a little amount of wet to the spray nozzle tip , which touch off the natural starches in cellulose , causing it to adhere to the interior of the caries .

4. Cellulose is an efficient, affordable alternative to other types of insulation.
When cellulose is counterpoint with other types of detachment , it ’s common to see one - for - one comparisons between cellulose vs. fibreglass insularity because both materials are low-priced and wide used in the residential building industry . likewise , the roentgen - time value , monetary value , and installation difficultness ofblown - in insulant vs. spray - froth insulationare often compare when homeowner are trying to decide on the upright insulating fabric to lend to their menage .
During these comparisons , most homeowner get along to find that cellulose is an free energy - effective material with low environmental impact that is project to be both fire - repellent and pest - repellent . to boot , cellulose can be inject immediately into finished wall or blow over existing fibreglass batts , and it has arelatively low-priced costthat form it a expectant pick for homeowners on a budget .
5. Cellulose insulation has an R-value of R-3.2 to R-3.8 per inch.
determine between several unlike type of insularity can be difficult , especially if you do n’t knowwhat R - time value isor how it impacts the quality of the insulant . R - value is essentially the measurement of how much heat resistance the material has per inch of deepness . With this in mind , you may liken the average cellulose insulation R - value , which pasture from R-3.2 to R-3.8 per inch to other rough-cut insulation materials to help decide on the proper insulation for your dwelling .
fibreglass insulation is a pop alternative for residential properties ; however , while it does have an low-priced cost , the average R - value is just R-2.2 to R-2.9 per inch . Mineral wool insulation is a good selection , ranging from R-3.0 to R-3.3 per column inch , while nebuliser - foam insularity can deviate depending on the specific eccentric used , with a minimal average R - value of R-3.5 per in and a maximum average R - value of R-6.5 per inch .
6. Blown-in cellulose insulation can be hazardous if not installed properly.
While there are many outstanding benefits to installing cellulose insulation , it ’s important not to overlook the likely hazards of this material , specially if it is not set up right . Since cellulose insularity is treated with fervour - resistant and pest - resistant compounds , airborne fibers can cause respiratory problems , middle irritation , or skin irritation , which is why installers need to fag appropriate protective equipment during the facility process .
Also , if the insularity is set up over release or too close to sources of ignition , there is an increased risk of the cellulose insulation catching fire , despite the fire - immune intervention . This is especially reliable if the insulating material is densely carry around electrical element and flammable material .
to boot , since cellulose is hygroscopic , it soaks up and holds water , so if there are anyleaks that go undetected , the cellulose insulation will hit it up up the excess water , causing it to sag or become compressed within the framing cavities . picture to water also has the potential to make the chemical substance components of cellulose insulation corrosive , which can lead to extensive price in the attic and inside the walls .

7. Cellulose insulation is naturally biodegradable.
After install cellulose insulation , you could expect it to last for 20 to 30 year before it will need to be replace . The one-time cellulose insulation will begin to naturally decompose as it reaches the remnant of this two to three ten lifespan , whereas other insulating materials , like fibreglass or foam , will stay on to run in landfills for significantly longer .
However , it ’s crucial to keep in mind that cellulose insulation is treat with firing - repellent and pest - resistant compound . The biodegradability of cellulose insulating material depends on the specific type of handling , though most cellulose material uses boric acid as a fire retardent , which is count to be biodegradable and can even help with healthy plant growth . For this understanding , cellulose insularism is wide considered a dark-green material that is eco - friendly and naturally biodegradable , reduce your carbon footmark and house waste .
