There are several types of insulation, and each one works best in certain parts of a home. Picking the right one helps keep rooms comfortable, lowers noise, and can reduce energy use. The main choices most homeowners and builders compare are batts, rigid foam boards, and spray foam.
Batt insulation comes in pre-cut pieces that fit between studs, joists, and rafters. Fiberglass batts are the most common and are easy to find. Mineral wool batts, like those made by Rockwool, resist fire and moisture well and help reduce sound between rooms. Batts are a good fit for open walls, attics, and floors during new builds or remodels.
Rigid foam board comes in large sheets of different thicknesses. It offers a high R-value per inch and can be used on basement walls, under slabs, on the outside of walls, and in tight spaces. Seams should be taped or sealed to stop air leaks.
Spray foam is sprayed into place, where it expands to fill gaps and cracks. Open-cell foam is lighter and helps with sound, while closed-cell foam is denser and adds a moisture barrier. Spray foam usually needs a trained installer and the right safety gear.
Other options include loose-fill insulation for attics and insulation board for special uses. Each type has an R-value, which measures how well it resists heat flow. Local codes set minimum R-values for walls, attics, and floors.
When comparing types of insulation, think about the space, moisture, sound control, and how easy it is to install.
