The new Pink® Superbatts® insulation products are specifically designed to meet the new H1 requirements and are extra wide to bridge thermal gaps and maximise thermal performance.
Single-layer solution: For residential ceilings, a single layer of Pink® Superbatts® R7.0 at the new width of 460mm can be installed. Segments should be notched and fitted between the truss chord to seal the thermal bridge.
Double-layer solution: Comfortech’s two-layer solution uses a first layer of high-density Pink® Superbatts® insulation that is the combined height of the truss chord and the gap to the top of the ceiling batten. This layer would be 110mm for a 90mm truss chord and an R-value of R2.6 or 160mm for a 140mm truss chord and R3.0. The second layer is our new Pink® Superbatts®, over-width 460mm wide R4.5. Installed at right angles to the first layer, with this method, the thermal bridge is completely closed. A lower R-value second layer can be selected where another compliance pathway method has been chosen.
