At Wolf Industries we are dedicated to providing the highest quality homes to our customers. We do this by making sure our homes are well insulated and energy efficient. One system we use is called Blow-In Blanket Insulation System, or BIBS for short.
How is BIBS different than standard insulation?
BIBS is made up of fiberglass blown-in wool specifically manufactured for this system. It is environmentally friendly since it is made with at least 25% recycled material, or cellulose – a plant-based fiber, and naturally nonflammable. It does not support the growth of mold and does not contain formaldehyde. The high density creates a tight fill around pipes, wires, sockets, and other irregular features to provide a high R-value and thermal protection.
BIBS has the highest R-value on the market today. In addition, the density provides excellent sound control, reduces air, moisture, pests, outdoor pollutants, and allergens within the framing cavities.
Installing BIBS requires special equipment to blow the fiberglass wool into the netting. The BIB netting, or insulation fabric, is attached to the frame. Then, using a blowing system, each cavity is pumped with insulation. This reduces the need for measuring and cutting, reduces the mess of handling traditional batt insulation pieces, and provides a high density compacted fill around all the homes’ features.
What is R-value?
R stands for resistance and refers to a materials resistance to heat flow or temperature conduction. The higher the R-value, the better the insulation, and the better climate control and energy efficiency it provides. It is measured per inch of thickness, so as an example, one inch of wood has an R-value of 1. The thicker the layer of insulation added, the higher the R-value increases.
At Wolf we use a combination of BIBS, batt insulation and spray foam insulation, depending on the location of use. All of our homes come standard with insulation that’s at or above the required code per IRC and IBC standards. With a Wolf Industries home, you are sure to be highly satisfied!
Could you give us some construction details pease:
With the BIBS system, is there a vapor barrier toward the inside of the building?
Does the insulation fabric breathe toward the outside?
What is BIBS R-value per inch?
I don’t think this statement is accurate: “BIBS has the highest R-value on the market today.” Higher than polyurethane boards at around R-7 per inch? Maybe you mean a higher R-value than fiberglass batting?
Where you pierce the membrane with wires, do you seal this and the other openings shown? How?
The top picture shows what may be a floor joist with what appears to be a pretty rough live edge. Is that a temporary board?
Yes, there is a vapor barrier.
The fabric breathes towards the outside.
The BIBS system has a rating of 6.25 R-value per inch.
BIBS has one of the highest ratings of conventional insulation methods.
All holes are sealed after with a Polyurethane Spray Foam
The board with a rough edge is just a temporary board replaced once siding is installed.
