Sticky mesh heavy duty.
Type 3 type 4 rigid insulation.
Also called styrofoam insulation this is the least expensive material.
For a 1 in thick 4 8 panel comes unfaced or with a number of different plastic facings.
Products with a higher r value have a higher cost but have an increased capacity to resist heat flow and therefore provide greater insulation.

It provides r values that range from 3 6 to 4 2 per inch.
Greenguard type 4 xps insulation board comprises 1 2 to 3 thick closed cell polystyrene xps with a minimum compressive strength of 30 psi.
When using rigid insulation in residential and commercial properties the most common boards used would be polyiso polyisocyanurate eps or xps each type of insulation board are very different and carry different r values and compressive strength.
Each type comes with unique advantages.
