Can I use cardboard as insulation?
As regards to its insulation properties, cardboard is actually a great insulator as it has poor thermal conductivity. Corrugated cardboards’ conductivity is estimated to be about the ⅓ of water’s conductivity and the same as fiberglass’ which is widely used for insulation.
Are polystyrene balls good for insulation?

Which is better cellulose or fiberglass blown-in insulation?
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.
Can I put fiberglass insulation over cellulose?
The existing insulation will dry once the cause of the moisture is stopped. Adding new cellulose insulation on top of existing fiberglass insulation is called “capping”. If you have some insulation in your sidewalls, cellulose can usually still be forced in with the dense-pack method to achieve the desired R-factor.
Can you put too much insulation in attic?
It’s possible to over-insulate an attic as too much will cause moisture buildup and eventually result in mold. Eventually, adding more insulation leads to diminishing returns in trapping heat as well.
Which insulation is best for attic?
Many people consider fiberglass batt to be the best attic insulation. It consists of plastic reinforced by small glass fibers. The batt version comes in blanket form — i.e., small, pre-cut sections that you can lay down wherever you need to.
