I laid down four 2'x4' sheets of plywood over the blown in insulation for access.
Blown insulation attic messy.
Hot air doesn’t get formed.
Install ventilation baffles (essentially plastic or foam vents) into the eaves by pulling the existing insulation away from the roof, positioning the new vent chute so the bottom extends six inches into the overhang and stapling it into place.
That said, in almost every case it's necessary to air seal prior to insulation installation.
If you’re filling your attic with loose fill insulation, you’re going to.
Tap pest control insulation comes in 30 lbs.
Blown in insulation is very messy if you need to access attic to maintain any equipment such as heat pump.
You need to track down your walls in the attic and dig through the existing insulation to find the exposed 2×4/drywall intersection.
Blowing in extra insulation can also seal small gaps and spaces as the material settles, keeping drafty air and excess noise out.
If the insulation is too dense, it can cause your ceiling to sag.
Laying down loose walking boards this solution is far more efficient and will not be messy!
It can be a little messy but that shouldn’t discourage you from doing it yourself because the energy savings that you can get from one day of work will continue to pay for themselves year after year.
Fiberglass loose fill insulation is lightweight, so be careful not to blow out the areas you’ve already filled.
There shouldn’t be any issues with it.
Keep in mind this process needs to be done all over the attic.
Also, as that outside air moves through the cellulose, pollen, bacteria, and mold spores can cling to it.
A better option is to blow additional insulation into the attics and walls rather than cut and place batts on top of the preexisting ones.
This process is less messy, quicker, and can save you money.
It requires a lot of work.
