Thicknesses and Availability:

Available in most popular thicknesses at most depots; short lead-times may apply if we need to get stock in before delivering to site.

This XR4000 Range includes the following available product thicknesses: 110mm, 120mm, 130mm, 140mm, 150mm, 165mm and 200mm.

Some thicknesses may only be sold in pack quantities, however, we will happily check to see if individual depots will split packs, depending on you requirements.

Due to supply challenges from the manufacturers, please allow extended lead times on all PIR boards. In some cases we may need to supply products from an alternate manufacturer - as a rule of thumb, Recticel and Kingspan are generally the most readily available in most geographic locations. Please feel free to Contact Me to check availability and lead times.
