This fiscal year’s Canada Wood technical projects include seeking for a 2-hour fire resistive ministerial approval for exterior walls.  This project is being done collaboratively between COFI and Japan 2×4 Home Builders Association.  On April 4th and 6th, outdoor side of the exterior wall specimens were burnt at a furnace equipped at Japan Testing  Centre for Construction Materials – one of the MLIT-designated performance evaluation bodies in Soka City, Saitama Prefecture (photo above).  The cross sectional of the wall consists of 3 layers of 21mm-thick gypsum boards (photo below).  2 replicates of the burning tests successfully satisfied the requirements.  As this was the outside burning, other tests of indoor side burning is scheduled on May 10th and 12th.
