O siding underlayment o pre cast wall panels. Neopor can provide up to 20 more energy savings than traditional white expanded polystyrene eps insulation. Frank kiesecker has served as vice president sales and marketing architectural products for ach foam technologies since 2005. Expanded polystyrene eps foam is a closed cell insulation that s manufactured by expanding a polystyrene polymer.

Unfaced 1 in thick xps has a perm rating of around 1 making it semipermeable. Eps costs 10 to 30 less than xps per equivalent r value and compressive strength. Xps products product features. However eps insulation has proven to perform just as well in such situations.

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. 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.

Xps comes unfaced or with a number of different plastic facings. 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. Ach foam technologies has made it easier for contractors and specifiers to see this with comparable features unavailable until now. In the past xps manufacturers were able to claim r values closer to 5 0 per inch.

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. The appearance is typically a white foam plastic insulation material the likes of which can be found as merchandise packaging.
