Is cellulose insulation OK?
Cellulose insulation is safe. It is made of paper, but the chemical treatment provides it with permanent fire resistance. There’s been static generated by the fiberglass industry warning that cellulose could burn. But independent testing confirms it’s safe and cellulose is approved by all building codes.
Is cellulose good for attic insulation?
The cellulose is blown into the attic or walls through long, flexible tubes that run from the blower to an application nozzle. The cellulose is allowed to fill the cavities or blanket existing insulation. No pressure is placed on the cellulose; it is allowed to settle over time. Walls are patched up and painted over.
Which type of blown in insulation is best?
Fiberglass
Fiberglass, cotton, and mineral wool can all work as loose-fill 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.
Which is better blown-in 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.
Is blown cellulose better than fiberglass?
Is Rockwool better than cellulose?
If your budget is larger, Rockwool is a great pick. It offers noise reduction as well as fire retardancy and thermal insulation. Cellulose comes in more forms and is DIY-friendly as well as more cost-effective.
