There are three types of r value to be mindful of.
The r value is usually measured based on the upward or downward direction of heat flow.
The higher the r value the better the thermal performance of the insulation.
An insulation product s resistance to heat flow is measured by its thermal and acoustic resistance or r value.
R value is the measurement of insulation s ability to resist heat flow.
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.
What does insulation r value mean.
