Over the years, manufacturers have developed insulation products that address the unique needs of a home’s envelope, from the basement to the roof. Using the best kind for specific locations provides better short and long term results.
Fiberglass Batts
Fiberglass batts are the most commonly used types of insulating products used in new and existing homes. Although fiberglass batts require protective breathing gear and clothing, they’re easy to install. Batts are also available as recycled denim or rock wool products.
- Batts are used in attics, walls and basement ceilings in both new construction and retrofits, but seldom used to increase existing wall insulation.
Loose-fill
Loose-fill products include cellulose and fiberglass. They’re blown into wall cavities and floor joists. They have similar heat resistance values as batt insulation. Cellulose, made from shredded recycled paper, is treated with borates to resist fire, moisture and insect infestations. Fiberglass is lighter than cellulose and additive-free.
- Loose-fill is used in retrofit situations for attics and walls, as well as new construction.
Sprayed-in
Sprayed-in products are the most expensive and effective materials that slow heat transfer. Applying them is not a do-it-yourself project because of the equipment used and skill it requires for an even application.
- Sprayed-in products are most often used in the nooks and crannies of walls and attics, or to fully insulate a roof deck in an attic retrofit. Sometimes it’s used as a roof coating on flat-roofed homes or those with vaulted ceilings.
Rigid Foam Sheets
Rigid foam sheets insulate more effectively per inch of material than batt and blown-in products. They are easy to cut and lightweight. They resist mold and insects and are waterproof. Some have a reflective foil side that resists even more heat transfer.
- Home improvement centers sell rigid foam kits for garage doors. Full sheets are often used to insulate basement walls where moisture is an issue. They’re sometimes used to insulate attic floor when spce is tight.
Familiarity with the insulation products available helps homeowners choose the best kind for the project. To learn more, contact Aggressive Mechanical Contractors, providing HVAC services for Monmouth County homeowners.
