Process of removing seat tracks and entire floor (as around old barroom had some damaged wood.
In the process I added new reflectix radiant barrier insulation and new MLV (mass loaded vinyl) it's 1lb per SF!! Old MLV was in bus over engine area but was damaged when we pulled up floor. So now New MLV is through entire bus floor and the 1/2 wood changed to 3/4 exterior grade and sealed plywood.
