spray foam on exterior
How does spray foam perform on the exterior of a building? I am working on a commerical building and we are looking at increasing the R value by installing spray foam on the exterior of the sheathing instead of installing batt insulation between the studs. The skin of the building will have 1.5" of stone and a 2" air space to the spray foam.I am guessing that the spray foam will perform fine because rigid insulation is commonly installed in this type of application. Let me know if I am way off base. Thanks |

Never done it but have read lots about this application and it's success. If I were building a building and doing drivit or any other exterior finish that needed a base insulation board, I'd foam it and finish it. |

Closed cell will perform fantastic in this application, even better than spraying it between the studs. You will have minimal thermal bridging and a true monolithic wall of foam. G |

It is a home-run application. Very efficient! |
