Eps Vs Xps Under Siding

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.

Eps vs xps under siding.

Xps products product features. Xps comes unfaced or with a number of different plastic facings. However the blowing agents used in the manufacturing process were known to deplete overtime reducing the insulation value. 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.

Polystyrene insulations eps and xps provider k 031 course eps 104 1 lu hsw sd. 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. Unfaced 1 in thick xps has a perm rating of around 1 making it semipermeable. Additionally eps is usually present in structured insulated panels.

Due to its physical properties xps has a higher r value than eps at 4 7 per inch. O expanded polystyrene eps is a durable rigid foam plastic material that is. Ach foam technologies has made it easier for contractors and specifiers to see this with comparable features unavailable until now. The appearance is typically a white foam plastic insulation material the likes of which can be found as merchandise packaging.

Neopor can provide up to 20 more energy savings than traditional white expanded polystyrene eps insulation. O siding underlayment o pre cast wall panels. Eps costs 10 to 30 less than xps per equivalent r value and compressive strength. O standard 25.

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. Frank kiesecker has served as vice president sales and marketing architectural products for ach foam technologies since 2005. 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.
