Continuous insulation on the exterior of the building is demonstrably superior to lofted insulation between framing. This traditional method results in a lower insulation value for the wall than the R-value of the insulation being used,due to thermal bridging and often questionable installation methods.
IKO Enertherm ALU is installed over the building wrap or RAB board, depending on the requirements of the build and as directed by the NZBC.
Lofted insulation may still be used within the wall as the overall dew point is moved outside the structure once the Enertherm is in place. This will depend on the wall build-up and the overall requirements of the building envelope. Please contact Outright Continuous Insulation for more details.
Outright Continuous Insulation has a complete range of accessories to enable fixing and sealing.
