Housewrap over interior basement insulation

gpellock

Can housewrap be used to cover and hold in interior basement insulation? We have synthtic instulation between studded walls and would like to cover the insulation with Lowes housewrap.

Interesting question.

The major issue, I think, would be flammability. I GOGGLED around a bit an could not find a definitive answer:

"DuPont™ Tyvek® is combustible and should be protected from a flame and other high heat sources. If the temperature of DuPont™ Tyvek® reaches 750°F (400°C), it will burn and the fire may spread and fall away from the point of ignition. For more information call 1-800-44-TYVEK. DuPont™ Tyvek® carries a Class I or NFPA Class A fire rating for flame spread and smoke developed index as measured by ASTM E-84."

I do know that Tyvek clothing is flammable, and not recommended for applications such as welding unless specially coated, and that special Tyvek is available for applications requiring lower flame spread.

Why house wrap? If for an air barrier, the ADA (airtight drywall approach) is a very commonly used method, and would very likely be a superior solution.
