Under Tile Marmox Insulation

Energy Efficiency Improvements

Marmox insulation boards significantly improve the energy efficiency of undertile heating. Recent changes to the NZ Building Code require heated floors in new homes to be insulated and in most cases Marmox exceeds this requirement.

To calculate if Marmox Insulation Board is sufficient insulation to meet the new regulations in your new home, simply divide the area of heated floor by the perimeter length of exterior walls in the room. If the calculated result is greater than 1.6, Marmox then Insulation Board is sufficient. If the calculation result is between 1.3 and 1.6, Marmox 10mm Insulation Board will meet the requirements of the code.

Example 1:
This example is based on a room that is 3 metres by 3.metres in size. The floor area of the room is 9 square metres. If only one wall of the room is an outside wall the perimeter wall is 3 metres long. A calculation of room area divided by length of perimeter walls is 9/3 equals 3. This value is 1.6 or above, so 6 mm Marmox board will comply with the NZ Building Code.

Example 2:
This example is based on a room that is 3 metres by 3.metres in size. The floor area of the room is 9 square metres. Two walls of the room are outside walls so the perimeter walls are 6 metres long. A calculation of room area divided by length of perimeter walls is 9/6 equals 1.5. This value is between 1.3 and 1.6, so 10 mm Marmox board will comply with the NZ Building Code.

Where the room area divided by the length of the exterior walls is less than 1.3 then an additional insulation product will be required as 10 mm board alone will not provide sufficient insulation. - Cosgrove Major 37708 Marmox Insulation Board Technical Review - November 2007
