Blown in blanket insulation (BIBS) is a top choice among insulation systems due to its impressive range of innovative and effective properties. If you are thinking about insulating your property, you should know that not all insulation is the same. Each system has its unique functions and applications. Discover why property managers of residential and commercial buildings often favor BIBS.
BIBS Insulation System: What Is It?
BIBS is an exceptional insulation system that utilizes specially manufactured fiberglass wool to insulate walls, attics, floors, ceilings, and other areas of a home. Unlike other insulation methods, BIBS forms a seamless "blanket" around obstructions like wires and pipes, ensuring a custom fit every time.
The system is supported by a proprietary fabric that delivers high performance and density. One of the key advantages of BIBS is its outstanding thermal efficiency, providing a high R-value of 4.2 at a cost-effective rate. BIBS makes the initial investment worthwhile by significantly reducing heating and cooling costs.
In addition to its energy efficiency benefits, BIBS even reduces air gaps more than 68% better than traditional batting insulation. It provides excellent sound control and can be installed in any climate. BIBS is also highly durable and consists of at least 25% recycled materials, making it a long-lasting, eco-friendly investment.
BIBS remains a popular choice for new and existing buildings with wood or steel frames. Its uniform density prevents settling issues that occur with other insulation systems. Besides, BIBS is naturally incombustible and does not support mold growth, even if moisture enters the wall cavity.
BIBS insulation is a certified system that meets the standard of Energy Star regulations for Grade 1 insulation. Homeowners should check with their contractors whether the BIBS insulation they intend to install uses the specific insulation fabric and fiberglass fibers that are BIBS system-approved.
How Is BIBS Different Than Fiberglass BATT?
Fiberglass BATT consist of glass fibers created from heated sand and held together by adhesives, with modern versions using acrylic binders instead of formaldehyde.
Compared to BIBS insulation utilization of pure adhesive-free fiberglass blown into a wall cavity behind a polypropylene fabric. This structure renders it inert and reusable, preventing moisture absorption and making it insect-resistant while warding off mold and rodents.
The fiberglass insulation is pre-cut and manually installed, causing itchiness due to adhesive exposure. Achieving proper density and filling voids might seem challenging, especially with irregular features. Contrarily, the BIBS system involves stapling polypropylene netting over the cavity and blowing fiberglass through a hose.
Unlike BATT insulation, BIBS requires certified contractors to secure uniform density and custom-fill the cavity, enabling a more precise and effective installation. For performance, fiberglass batts have an R-value ranging from R 2.9 to 3.8, with installation challenges often revealed through thermal imaging.
On the other hand, BIBS boasts an R-value of 4.2 per square inch, offering higher insulation efficiency. Fiberglass is often used and cost-effective, with lower insulation costs but more potential drawbacks when poorly installed.
In contrast, BIBS insulation usually requires a slightly higher investment-typically costing 30% to 50% more than fiberglass BATT. However, it justifies this expense by delivering a superior R-value, exceptional cavity filling, and excellent sound control. These traits make this insulation system regarded by building owners as a worthwhile investment.
Is BIBS Better Than BATT?
Blown-in insulation is better than BATT in many cases. However, some homeowners preferred fiberglass batting insulation due to its effectiveness, efficiency, and installation cost. BIBS insulation is often more suitable for addressing under-insulated walls and crawl spaces, making it the best choice for re-insulation projects.
Otherwise, reinsulating with standard fiberglass BATT would necessitate removing the drywall to access the space between joists, a costly, messy, and time-consuming project.
What Is BIBS Insulation Made Of?
BIBS insulation consists of cellulose, a nonflammable plant-based fiber that enhances a building's fire safety.
