Insulation
BASIX DIY calculates the minimum insulation requirements for your dwelling, based on:
-
the climate zone.
You must select "yes" to pass BASIX Thermal Comfort using the DIY method. If you select "no" then you will need to use the Simulation method, which may be appropriate if you would like to:
-
install better glazing to offset lower levels of insulation;
-
install more insulation and reduce the estimated heating and cooling loads; or
-
trade performance between the ceiling/roof, walls and floor.

Additional Insulation Commitments
BASIX Do-It-Yourself (DIY) sets the minimum insulation requirements for walls and ceilings. BASIX allows you to commit to a higher level than the minimum insulation requirements in order to improve thermal comfort and reduce heating and cooling energy consumption. The R values of the additional insulation are entered in the Construction Details section of BASIX.
R-Value of Construction without insulation
The R-Value of the construction is the sum of the thermal resistance of each layer, and external and internal surface air film resistances. This excludes any additional insulation.
TOTAL insulation required to be installed (R-value)”
This is the total R-value of insulation that must be installed. It includes the minimum insulation requirements calculated by BASIX plus any additional insulation commitments.
Reflective foil
Reflective insulation has a thin layer of reflective foil on one or both sides, and is designed to reflect heat.
Thermal Bridging
Thermal bridging is an unintended path of heat flow, using a path of least resistance through a building envelope between the outside and inside.
Garages, Carports & Verandahs
Confirm requirement for insulation to garages.
Roof and ceiling insulation does not need to be installed in carports and verandahs.
