Bibbs vs Batts Wall Insulation

AT JAMES MULLEN CUSTOM HOMES, WE ENCOURGE OUR CUSTOMERS TO UPGRADE TO HIGHER PERFORMANCE INSULATION. IF YOU ARE A COST CONSCIENCE HOMEOWNER AND CANNOT AFFORD OR JUSTIFY THE COST OF FOAM INSULATION, THEN WE FEEL THE BEST VALUE FOR YOU INSULATION DOLLAR IS THE BIBS SYSTEM. HERE'S WHY:


The BIBS system is a high-performance insulation system that places fiberglass blowing wools into the walls behind BIBS system fabric/netting. This process forms a seamless blanket of insulation that completely fills around pipes, wires, and other objects inside the wall cavity, eliminating costly voids and air gaps. The end result creates a thermal envelope and makes the building more energy efficient. The Blow-in Blanket System (BIBS) is fiberglass insulation taken to a higher level using the best qualities of the fibers. All insulation systems are compared to fiberglass batts. The fiberglass fibers are engineered to be blown into a cavity behind netting filling the cavity to a uniform density no matter what the shape. R value is 4.23 per inch. Using pure fiberglass with no adhesives it is inert and can be reused. BIBS does not support mold, insects or rodents. It does not absorb moisture and it does not burn. There is no off-gassing. By filling voids as well as it does, sound suppression is very good. The installation of the Blow-in-Blanket System is what mainly sets this insulation apart from any other system. Polyproylene netting is staples tightly over the cavity. A hole is then poked in the netting, the hose inserted, and the cavity is filled. By blowing in the fiberglass the cavity is custom filled to the correct density. BIBS in 2 x 6 construction equals R-23 and in 2 x 4 it is R-15 which is about as much R value as is currently available in that cavity depth. The Passive House Institute US founder calls blown in fiberglass the most cost effective insulation. BIBS cost is more than fiberglass batts, though this cost is a higher R-value also, and again, it fills the cavity much better. Blown in fiberglass using the smaller fibers is also very effective in dense packing existing walls. 2.25# of fiberglass has the same or less air infiltration as cellulose, which is the other commonly used dense packing material. The fiberglass is a higher R-value and doesn't have to the be packed in so tightly as cellulose.


Energy Efficiency


With energy prices increasing more than 4% annually, energy-efficient homes are on the minds of today's homebuyers. Fiber glass insulation is a proven energy-saving measure that is most commonly used in homes built today. However, many traditional fiberglass applications, like batt and other dense pack insulation systems leave gaps and may settle, leading to heat loss. The BIBS system offers a solution that maximizes energy efficiency for minimal up-front cost compared to expensive foams and saves you heating and cooling costs. In addition to the added comfort of a superior insulation system, these savings are something homebuyers enjoy for the life of their home.


Consistent High Performance



A building insulated with the BIBS system has advantages that last the life of the structure. The BIBS system helps achieve a complete thermal envelope with virtually no gaps or settling. This results in maximum comfort, increased sound control, and energy savings in heating and cooling costs. The BIBS system provides for complete coverage against humid air currents and helps protect against moisture absorption without rot or deterioration can increase the durability of the building. Fewer building problems mean happier home ownership.
