Used in roof wall floor below grade structural geofoam applications.
Rigid expanded polystyrene insulation panel for walls.
Some products have reinforced facing to make them sturdier.
While all foam insulation products are derived from petroleum some of the key differences include water resistance r value per inch compressive strength facings permeability to water vapor and evidently cost.
Choose this option for areas that need a good amount of strength and water resistance.
Pir polyiso or iso is a thermoset plastic product typically produced as a foam and used as rigid thermal insulation panel most often with aluminum foil facing.
Expanded polystyrene eps extruded polystyrene xps and polyisocyanurate are the most used types of rigid foam insulation.
Rigid foam insulation commonly called styrofoam insulation is made up of expanded polystyrene or eps panels that are secured to basement walls to increase the wall s r value.
Expanded polystyrene eps the most versatile of the three rigid insulation options.
Also called styrofoam insulation this is the least expensive material.
Used most widely in insulated concrete forms and structural insulated panels.
