We maximise our isulation options, where ever we can.

For example, if we have a floor cavity that is 200mm, then we put 200mm batts in the space, currently R3.0^*.  When dealing with 90mm cavities we can fit R2.5 batts, filling spaces like internal and external walls. In the ceilings we install 400mm batts that are rated R4.0.

We use Tontine Thermal Insulation, as these batts are made from a minimum of 83% recycled post-consumer fibres.

^*(The R-value is a measure of thermal resistance)
