R value is the measurement of insulation s ability to resist heat flow.
Find your zone on the map and then use the above insulation r value chart to determine the level of insulation you need to properly insulate your attic walls floors and crawlspaces.
Higher r values mean the product offers a more efficient level of insulation.
Choosing the best insulation for your home is important that s why we recommend you consider all your options beforehand.

In hot and humid climates bulk insulation such as pink batts ceiling insulation is often installed in combination with a reflective foil sarking which does a great job in reflecting the radiant heat and adds to the total performance r value of the home if you are building a new home then consider installing foil faced roofing blanket in addition to ceiling batts.
An insulation product s resistance to heat flow is measured by its thermal and acoustic resistance or r value.
The table below shows what levels of insulation are cost effective for different climates and.
These r values are a sum meaning this should be the total r value once you add up the entire depth of insulation.
Insulation level are specified by r value.
R value is a measure of insulation s ability to resist heat traveling through it.
Winter r values refer to the product s resistance to heat flow directed upwards while summer r values pertain to the thermal resistance to heat flow downwards.
The higher the r value the greater the insulation performance.
Brisbane insulation offers a range of ceiling insulation r values to best suit your budget and more importantly your families comfort level.
What does insulation r value mean.
Recommended home insulation r values.
When determining how much insulation you need don t guesstimate calculate.
The insulation must achieve a minimum r value of 1 0 in zones 1 to 7 and a minimum r value of 2 0 in zone 8.
The insulation must be water resistant and be continuous from the adjacent finished ground level to a depth of 300mm or for at least the full depth of the vertical edge of the concrete slab on ground.
