Every insulating materials has its own R-value.

The R-value is actually the thermal resistance. The higher the value the higher the thermal transfer. Check the R-values of every insulating materials that you can find and compare the benefits.

Loose insulation

This type of insulation is similar to the blanket insulation only that it’s in loose form. It can be installed using a blowing machine. If can cover any area and it will harden to form a solid insulating barrier. It won’t set hard enough to walk on it, so you should consider installing some plywood sheets.

Spray foam

This is a newer method for insulating your home. The problem is that it needs to be done by professionals. The roof is insulated by spraying the foam onto the underside of the roof and not into the joists. The R-value is of 6.5 per inch, while fiberglass has a 3value per inch. It may not be cost effective to insulate your house with spray foam if the area is large.

Reflective insulation

There are many advantages with this rigid/reflective insulation. It can be installed on the floor and you can walk on it. It is easy to install on roof tops.

More and more, recycled fibers are being used for insulation. Also recycled plastic bottles are great as insulation.
