According to Johns Manville representative Mike Fay the smaller fiberglass nodules in todays loose-fill insulation significantly improve cold. Unless you opt for spray foam then the insulation choices normally come down to cellulose and fibreglass.

Cellulose uses mainly recycled material and requires less energy than fiberglass to make.
Fiberglass vs cellulose insulation for attics. In addition to its great R-Value Cellulose also provides sounds insulation by providing mass and dampening. A Fight for R-Value. However like the cellulose it is one of the most cost-effective soundproofing materials you can use for.
Loose-fill fiberglass in their attics with 2 in. Today we are going to look at two of the most common materials used as blown in insulation. Cellulose Insulation is two to three times denser than similar fiberglass products.
Blown in insulation is a versatile product that can be used throughout a home. In open attics Cellulose Insulation molds around irregular construction and stays in place eliminating potential leaks for sound transmission. So what are the advantages and disadvantages of each of these.
The blown-in insulation is mixed with water during the process and without the barrier can cause damage. It is able to improve energy efficiency home comfort and lower utility costs. But unlike the cellulose fiberglass is made of synthetic materials making it less environmentally friendly.
Cellulose wins Last Update. Pros and Cons Written by Krystal Miller on Dec 30 2009. Of the two fiberglass has been around the longest is more commonly used but cellulose has been gaining a lot of traction in recent years as people strive to lower their energy bills.
Cellulose insulation comes with fewer health risks than installing fiberglass. Cellulose however does offer more depth in r-value. Cellulose insulates better than fiberglass especially in very cold weather.
Fiberglass Insulation vs Cellulose Insulation. The two main least-expensive and most commonly used residential insulation materials is cellulose and fibreglass. Cellulose Cellulose Insulation offers many advantages to your home such as its R- Value of R 26 per 100mm metric which is better than glass wool or rock wool.
When using cellulose blown-in dry insulation it requires a machine to achieve its purpose and a training session from wherever you rent the blower from. Blown Fiberglass vs. It takes 12 thickness or more of Fiberglass to secure an R-30 rating while Cellulose material only requires the thickness to be 81 to gain the same R-30 rating.
Like cellulose fiberglass is also commonly used to insulate attic or other areas of the house. Fiberglass vs Cellulose Insulation and Moisture Installation is the key to benefiting from either type of insulation and when installing cellulose insulation a vapor barrier will be required. Using this product means that youre saving on both energy and the cost of creating new materials for insulation.
Rather than trying to meticulously lay fiberglass insulation over the attic homeowners and builders can simply blow cellulose insulation throughout the attic. Fiberglass R-value tends to range between 22 and 43 depending on the density of the material whereas for cellulose the R-value ranges between 32 and 35. This means cellulose insulation has a slightly higher average R-value than fiberglass but high-quality fiberglass provides better thermal resistance than high-quality cellulose.
Both cellulose and fiberglass insulation have their pros and cons but I feel that cellulose is the better bet overall. In the summer according to research by the Brookhaven National Lab fiberglass loses 3 times more R-value than cellulose when attics reach 110 degrees F very common in most. Fiberglass insulation is the easiest insulation product on the market to install and if installed correctly the most effective product on the market for home attic insulation.
This effectively stops the problematic convection currents. When used in an attic space however both types of insulation are ineffective at air flow across the attic floor such as a strong gust of wind. When installed cellulose insulation completely eliminates voids and gaps blocking the avenue for sound travel.
It is the most cost-effective and common insulation material today. To ensure our content is always up-to-date with current information best practices and professional advice articles are routinely reviewed by industry experts with years of hands-on experience. When it comes to insulating your home and specifically your attic there are two commonly used materials for the job and thats fiberglass and cellulose.
This allows the insulation to get into the small pockets and crevices that fiberglass wouldnt. If fiberglass batts become compressed losing some of their air pockets then this insulation may be more affected by air flow than cellulose which performs well regardless of density.
