What is better attic insulation fiberglass or cellulose?
At 3.5 per inch of material, the R-value of blown-in cellulose is 23% better per inch than fiberglass batts! According to research done at the Oak Ridge National Lab, fiberglass loses up to 50% of its R-value in very cold conditions; making cellulose a better choice for homes in northern climates.
What is InsulSafe?
InsulSafe is an industry-leading fibre glass blowing insulation used in residential and commercial construction as a thermal and acoustical insulation. It is unbonded, white, virgin fibre glass designed for pneumatic installation in open areas and treated to minimize dust and static electricity during application.
What’s the difference between cellulose and fiberglass insulation?
Fiberglass and cellulose are both used for thermal insulation and come in a range of r-values. Fiberglass is quicker to install and offers more protection against mold and mildew growth. It is the most cost-effective and common insulation material today. Cellulose, however, does offer more depth in r-value.
Which cellulose insulation is best?
The best manufacturers of cellulose insulation include GreenFiber, Insulmax, Applegate, and Nu-Wool. RetroFoam of Michigan has more than 17 years of experience specializing in injection and spray foam insulations. While we specialize in foam, we have dealt with cellulose in homes that needed new or updated insulation.
What type of insulation for attic is best?
Fiberglass, cotton, and mineral wool can all work as loose-fill insulation material, but the far and away top choice for blown-in insulation is fiberglass. Contrary to batts insulation, blown-in fiberglass insulation is perfect for filling in tight voids around wiring, pipes, or any area with awkward framing.
Why is cellulose cheaper than fiberglass?
Low-price – Because cellulose is primarily made out of paper, it’s an even more inexpensive form of insulation at about 75% of the cost of fiberglass. Easy Installation – Cellulose comes in small pieces and there are many ways to install it, so it fits well with most homes’ structures but can be very messy to install.
What is blown in attic insulation?
The term blow-in insulation (or loose-fill insulation) refers to the process of filling stud or joist cavities or covering attic floors, with any loose material that has a good insulating R-value.
Does cellulose insulation settle more than fiberglass?
Because fiberglass insulation has a low R-value, it needs to be installed in thick layers to be effective. The dense volume of fiberglass insulation prevents settling. Cellulose insulation, unfortunately, is most likely to settle.
How long does cellulose insulation last?
30 years
Cellulose Insulation–Made from recycled paper, this insulation does a spectacular job of keeping the house temperature controlled. With a lifespan that can last up to 30 years, it’s a green and effective choice.
Does cellulose insulation need a vapor barrier?
A common misconception is that vapor barriers are required in all insulation installations. With Modern’s Cellulose insulation, a vapor barrier is not recommended except in very cold weather or high moisture areas such as spas or pool buildings.
What insulation has the highest R-value?
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.
Why is cellulose insulation better than fiberglass?
This is due to the extreme difference in temperature between the interior of the house and the exterior, and the way that fiberglass insulates, which is by creating a small air pocket. Cellulose insulation does not break down or lose its R-value in extreme cold, which makes it a better insulation in cold climate areas.
Is cellulose insulation harmful to my health?
Cellulose insulation, being made of paper, does not pose any health issues to the installer or home occupants. Cellulose is treated to help prevent rot, decay, and mildew but may still develop these issues if there is prolonged contact with moisture.
What should I look for when buying cellulose insulation?
Cellulose Insulation 1 R-Value . Whenever you purchase insulation for your home, you will notice that it has something called an R-value. 2 Installation . Fiberglass insulation comes in two forms, batts and blown-in. 3 Flammability . 4 Durability . 5 Extreme temperatures .
What is insulsafe SP?
InsulSafe SP is a fiberglass blowing insulation used in residential and commercial construction as a thermal and sound absorbing insulation. It is designed for pneumatic installation in open (attic) and closed (sidewalls/floor) construction cavities.
