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.
Ceiling insulation r value brisbane.
An insulation product s resistance to heat flow is measured by its thermal and acoustic resistance or r value.
Higher r values mean the product offers a more efficient level of insulation.
R value is the measurement of insulation s ability to resist heat flow.
When determining how much insulation you need don t guesstimate calculate.
Insulation level are specified by r value.
R value ranges from 1 5 to 7 and the higher the insulation s r value the better that product is at insulating your home.
The higher the r value the greater the thermal efficiency.
What does insulation r value mean.
In australia ceiling insulation is available in a variety of brands and r values ranging from a r3 5 to r7 0.
R value measures how well certain building insulation materials can resist heat.
R value is a measure of insulation s ability to resist heat traveling through it.
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.
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.
The r value is usually measured based on the upward or downward direction of heat flow.
The thickness mm of ceiling insulation is measured by r values.
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.

Measures insulation s resistance to heat flow out of the.
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.
Know exactly how much you need with our project calculators.
These r values are a sum meaning this should be the total r value once you add up the entire depth of insulation.
An uninsulated ceiling can contribute to 35 of your homes winter heat losses and summer heat gains.
