Foam Wall Insulation - Structural Benefits



Clemson University has been researching the use of spray foam as an enhanced attachment system for roofing.  This research centers on how to retrofit or construct buildings to be more resistant to hurricane and other high wind events.
Clemson’s research shows that spray foam can significantly improve the attachment of roof sheathing to trusses and rafters, similar to the way construction adhesives help bond a floor system together.  In a retrofit case, foam can be sprayed on one or both sides of the sheathing/rafter intersection from inside the finished roof.  In new construction, spray foam can be applied to the entire roof system.  The spray foam makes a significantly stronger roof than either nails or screws alone.  More information on this research is available from Clemson University’s Civil Engineering Department, or the 113 Calhoun St Project in Charleston, SC.
