Whats the difference in Uvalue?Aprox 50% more insulation
What is the real difference between these 2 depths other than cost and loss of space?

You'll get technical details of the thermal conductivity for each product, but u-value needs to look at whole construction.I thougt the same would apply to each grade of insulation
