This is one of the most effective types of insulation as it offers the highest R-value. Properly installed spray foam insulation can provide air and vapour barrier. One of the huge benefits of this type of insulation is the added cost savings in heating and cooling bills. Because this is applied using a spray, it will seal awkward spaces that are usually left behind while using other types of insulation.
Fiberglass insulation is generally the most common type of insulation used - it is most likely the insulation that you have in your house. Fiberglass can be used to insulate exterior walls, floors, attics, and ceilings. This type of insulation can be fitted between studs, joists and beams.
Mineral wool has been around for a long time. It is usually made from melting stone and recycled materials. Fibers are spun and formed into batts or boards. One of the advantages of mineral wool is that it offers a slightly higher R-value. It also provides excellent water protection as these fibers don't absorb water and stay intact even when wet. Mineral insulation also has better sound-proofing properties.
Blown-in cellulose or fiber glass insulation will help you insulate your attic properly and also help save you money on your energy bills. You could see your energy bills reduce as much as 15%-25%. It also provides a level of sound dampening. This type of insulation is generally treated to be fire resistant. Blown-in insulation is a very cost-effective way to properly insulate and secure your attic.
