Rigid boards carry the U-value calcs for floors, flat roofs and cavity work, and sheet prices swing hard between suppliers. Live discounts on PIR, phenolic and EPS boards in the common thicknesses from 25mm up to 150mm are compared here, biggest saving at the top. Price per square metre is the number to watch, as sheet sizes vary between brands.
