What are the different types of home insulation?

For a home to be energy efficient, insulation is a crucial element. It limits heat transmission and is typically installed in places where air escapes, such as in the attic and between the stud cavities inside walls. Homeowners can save an average of 15% on heating and cooling expenditures by caulking air leaks and providing adequate insulation to the attic, crawl spaces, and basement.

Here’s a rundown of some of the types of insulation offered by insulation services.

·      Spray Foam Insulation

Leaks and holes within preexisting walls are sealed with spray foam insulation. Spraying liquid polyurethane into the wall cavity causes it to expand and harden into a solid foam.

There are two types of spray foam: open-cell foam and denser closed-cell foam. Although it can be pricey, closed-cell foam boasts one of the highest R-values of any insulation, at about R-6.2 per inch. Consider hiring a professional that can help with insulation services to complete the work if you decide to use spray foam.

·      Blanket Batts and Rolls

The blanket batts and rolls comprise fiberglass, though there are also varieties made of mineral wool, cotton, and plastic fibers. Given that the materials are made to fit inside the typical width between attic rafters, wall studs, and floor joists, this insulation type is among the least expensive and easiest to install on one’s own. It is best for DIY insulation of unfinished ceilings, walls, and floors.

·      Foam Board or Rigid Foam Panels

Foam boards and stiff foam panels can be used to insulate both a floor and an unvented low-slope roof. They lessen the amount of heat that is transferred through wood, wall studs, and other building materials.

This kind of insulation is used by many homeowners for both the outside and interior wall sheathing. It is great for insulating unfinished basement and foundation walls, as well as ceilings and floorings.

·      Rockwool

For typical residential wood-framed structures, Rockwool, or mineral wool manufactured from extruded lava rock, is an excellent insulating material. This substance is formed from lava rock that has been spun at high speeds to produce thin, fiberglass-like strands of material. It resists fire and moisture and insulates against sound and heat transfer. Although this is quite expensive, it is great for ceilings and walls. Opt for this if you are interested in noise-dampening and fire-resistance.

Other types of insulation offered by home insulation services are cellulose (which is great for attic floors); structural insulated panels (which is best for timber frame open walls and new construction); and concrete block insulation (which is great for concrete block walls).
