Finally using the purchased insulation and sound proofing materials and realizing what a difference! Cut down the cold transfer on the floor dramatic and able to insulate under 3/8 ha to Hardie back and a thin sheet of aluminum sheeting to keep the insulation sturdy and not fall into the floors ridges for plans of circulation air for moisture.saved alot of head room . Thank you Fraser good product and to mention the Fraser River , good flow .
