System Description: Suspended Timber Floor, Sealed Airspace above Foilboard, Enclosed subfloor, 19mm Tongue and Groove Flooring. 140mm x 45mm timber joist at 450mm c/c. 300mm x 50mm Pine Bearer at 3600mm c/c. Ground Thermal Resistance based on subfloor ventilation area per perimeter length 6000mm2/m = R0.58 heat flow out and R0.56 Heat Flow In. Foilboard Installed antiglare up. Fully Sealed air space assumes no dust cover on upward facing surfaces. Enclosed cavity to prevent air ingress. Calculated per AS/NZS 4859 Part 1 & 2:2018. Added Insulation R Value includes the material insulation R Value and the R Values of the associated reflective airspaces within the insulation system less non-reflective enclosed subfloor air film. If elements of construction vary from that described, this may produce a different thermal resistance result.
