Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation.
Cellulose insulation finished attic.
For diy attic insulation you ve got two choices.
Walls are patched up and painted over.
Assuming your current attic insulation is made from fiberglass and has a value of r 13 you d have to add roughly 10 inches of additional fiberglass to hit r 38.
Or 7 inches of cellulose.
Blown in cellulose is an environmentally friendly material made from recycled newspaper so it s easier on your skin and lungs.
You can get to the same place with either material.
Cellulose blown in ceiling insulation is a good choice for diyers.
Loss of insulating value.
Wet insulation no longer performs its primary function of inhibiting heat transfer.
The two most common types of insulation fiberglass batts and blown in cellulose loose fill are vulnerable to attic water damage in two specific ways.
Saturated insulation typically loses at least 40 of its insulating r value.
The cellulose is allowed to fill the cavities or blanket existing insulation.
Cellulose can slow down air flow particularly in walls.
The cellulose is blown into the attic or walls through long flexible tubes that run from the blower to an application nozzle.
Blown in cellulose has a higher r rating and is less expensive than either blown insulation like fiberglass attic insulation or fiberglass batts.
It can be effectively blown over existing insulation and.
No pressure is placed on the cellulose.
Pros and cons of loose fill fiberglass attic insulation.
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.
