Dense-packed cellulose: The only difference between dense-packed and loose-fill cellulose is how it’s installed. This type of insulation is blown into the wall with more force, ensuring a denser layer and more even spread.
What is loose fill insulation?
Loose-fill means it was blown in through holes at the top and bottom of the walls with low pressure, and that it falls short of the 3.5 lbs of cubic foot density it needs to be considered dense-packed cellulose (more on that shortly). This is the choice of many DIY handymen who want to spend as little as possible and do the job with a blower from a local hardware store. Do I recommend this? Not really. This sort of job leads to spotty and uneven density because you can’t ensure it distributes evenly inside the wall. If you know how a radiant barrier works to keep out heat, you’ll know this won’t be good news.

How much heat does aluminum foil give off?
Shiny side reflectivity is about 88%. It definitely picks up some heat. But it also conducts heat well, so loses it to cooler ambient air rapidly. It stays close to ambient temperature. Most of the heat gain at your windows is radiant, so with aluminum foil on the inside, you have reduced your radiant heat gain by about 90% . That’s pretty good. In direct sun you’ve got maybe 70–100 watts/sq.ft hitting the window, depending on angle, so with foil on the inside, with glass transmittance losses, that’s reduced to a heat gain of about 7-10 watts/sq.ft. So for a 3′x5′ window, you’d have about 105-150 watts of heat coming in through the aluminum.
