BIB refers to the Blow-In-Blanket fiberglass insulation process where walls are netted and insulation can be blown into exterior walls and / or interior walls. It's very effective and creates a higher R-value than Batt insulation.
For instance, R15 for a 2x4 wall or R23 for a 2x6 wall. This type of system will not settle. You'll find skilled technicians at Dakota Insulation that are specially trained in this process. Get in touch
