Eps Vs Xps Under Siding

Additionally eps is usually present in structured insulated panels.

Eps vs xps under siding.

Extruded polystyrene xps foam is a rigid insulation that s also formed with polystyrene polymer but manufactured using an extrusion process and is often manufactured with a distinctive color to identify product brand. Compatibility xps vs eps insulation for contractors working with a building made of concrete xps tends to be the preferred form of rigid foam insulation. Unfaced 1 in thick xps has a perm rating of around 1 making it semipermeable. Expanded polystyrene eps foam is a closed cell insulation that s manufactured by expanding a polystyrene polymer.

Extruded polystyrene xps easily recognized by its blue green or pink color xps falls in the middle of the three types of rigid foam insulation in both cost and r value about r 5 per inch. However eps insulation has proven to perform just as well in such situations. O expanded polystyrene eps is a durable rigid foam plastic material that is. Since eps is lower cost per inch than xps and is available in a range of compressive strengths from 10 to 60 psi using it belowgrade and under slabs can save on insulation costs.

O standard 25. Due to its physical properties xps has a higher r value than eps at 4 7 per inch. Eps costs 10 to 30 less than xps per equivalent r value and compressive strength. Neopor graphite polystyrene gps is highly efficient rigid foam insulation used in various remodeling and new construction applications such as behind new siding below grade and below slab.

O siding underlayment o pre cast wall panels. The appearance is typically a white foam plastic insulation material the likes of which can be found as merchandise packaging. Xps products product features. Polystyrene insulations eps and xps provider k 031 course eps 104 1 lu hsw sd.

Frank kiesecker has served as vice president sales and marketing architectural products for ach foam technologies since 2005. In the past xps manufacturers were able to claim r values closer to 5 0 per inch. Xps comes unfaced or with a number of different plastic facings.
