An additional patent application was made to protect various methods of manufacturing VentBoard™ and DuctBoard™ (13/782,406).  This application makes 12 claims for sophisticated methods of VentBoard™ production.

There is now an International Patent Pending (PCT/US2011/048786).  Not only does this International Patent application extend protection for VentBoard™ and DuctBoard™, but also incorporates many new enhancements, improvements and additional features to the original invention.  In particular, it now includes manufactured / tooled / extruded elements of all configurations and construction for the matrix elements allowing ventilation rations of up to 1/50  as well as the strong and versitile DuctBoard™ floor sheating panel and air distribution system.  

This international application lead to the filing for patents for all products in Canada (CA-2,796,095) and (CA-2792,344) and (CA-2,804,434).
