Overall Conclusion

Walls with higher CR i.e. that contain adequate C-values and R-

values are preferred for minimising heating and cooling energy

consumption in all of the climate zones.

In many regions, the R-value of the wall system plays a significant role

in reducing energy use. However, with sufficient C-value, minimal levels

of additional resistance are required to achieve reduced energy

consumption.

R-value alone is inadequate to achieve desired energy

consumption levels.

Overall Conclusion

From a long term cost perspective, the optimal solution is to use

a cavity wall, with face brick exterior and add only the insulation

required for the specific building design and climatic conditions.

In some cases, a well sealed air cavity will suffice.

Benefits of RoxulEnergy Saver Cavity Wall Insulation

Contributes significantly to achieving a high

home energy rating.

Completely water repellent whilst allowing the

cavity to breathe.

Improves sound performance properties of

the wall.

Reduces heat flow through sun-prone walls in

summer.

Assists with thermal mass of cavity walls to

provide greater winter comfort.

Completes the building insulation envelope.

Installed in existing walls easily.

Made from 100% recycled material.
