Do you have something that says you can use BIBS HP in basements?

As long as the following BIBS and BIBS HP parameters are met, and local code requirements are followed, the BIBS HP system can be installed in a basement application:
1)      An approved closed-cell foam from the following manufacturers, installed at the correct thickness:
BASF Polyurethane Foam
Certa-Spray (CertainTeed)
Convenience Products Closed Cell
Fomo Magnum

* NOTE:  only Convenience Products and Certa-Spray are endorsed members of BIBCA

2)      An approved glass fiber from the following manufacturers, installed to the correct density: 

CertainTeed’s  SP (at a 2.3 lb density)
CertainTeed’s Optima (at a 1.8lb density)
Johns Manville’s Climate Pro (at a 2.3 lb. density)
Johns Manville’s Spider (at a 1.8 lb density)
Knauf Jet Stream Ultra (at a 1.8 lb density)
3)      The fiberglass must be blown behind the BIBS®,  BIBS HP® fabric.
It can only be secured through the R-Factor office in Aurora, CO, or one of its direct, approved, distributors.
4)      There must be in installation of a Class II vapor retarder on the warm side of the wall configuration per code requirements.
5)      The BIBS HP® system can only be installed by a trained, tested and certified BIBS®-BIBS HP® Contractor in good standing (current contract and certification on file at the R-Factor/BIBS office in Aurora Colorado)
If all of the above criteria is met, then it’s an approved BIBS HP® application.

codes MUST be followed in each area. BIBS in no way implies that every municipality accepts foam below grade/on concrete walls as a standard. Check with local city code offices to make sure there is no restrictions as far as this application on concrete/below grade.

This is a climate specific issue as well as a best practices problem. Best practices is to always put rigid foam on the outside. Cement wicks water, and it has to dry either inside or out. In a cold climate it has to dry in. Not sure about warm climates. By insulating the inside of a cement wall, you make the wall wetter in a cold climate so you must NOT use a vapor retarder on the inside. Contact Pat Huelman from the U of Minnesota. He has a class called Insulating a Basement, It does Not Get Riskier Than This.
