Insulation is an important part of building and maintaining a home’s energy efficiency. The two most common forms of insulation are blown insulation and batt insulation. Each offers a variety of benefits that increases your home’s ability to retain desirable temperatures throughout the year.
While both insulating materials offer great insulating properties, blown insulation provides a seamless blanket over floor joists and between wall studs for better coverage. Batt insulation requires more patience during installation to prevent gaps that can lead to heat transfer.
Batt insulation provides an instant R-value rating, which is the insulation’s ability to resist heat transfer, predetermined by the manufacturing company, while blown insulation needs several applications and professional installation to achieve the required R-value.
Ease of Installation
Blown insulation contains an adhesive that helps the material stick to surfaces during construction of open cavities. Blown insulation provides a non-evasive approach when forced behind walls via drilled holes. Batts are precut to fit between joists and studs, making them easier for homeowners to install.
Areas of Use
Blown insulation works better for small, odd-shaped rooms that are difficult to reach, such as attics and crawlspaces. Batt insulation is easier to install in larger spaces, floors and ceilings because it creates less mess.
Prices for materials and insulation vary by region and material, although in many areas blown insulation tends to cost less and provide more value for your money. Compare quotes from several contractors as well as do-it-yourself estimates when evaluating insulation costs.
