O expanded polystyrene eps is a durable rigid foam plastic material that is.
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.
However the blowing agents used in the manufacturing process were known to deplete overtime reducing the insulation value.
The appearance is typically a white foam plastic insulation material the likes of which can be found as merchandise packaging.
O standard 25.
However eps insulation has proven to perform just as well in such situations.
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.
Neopor can provide up to 20 more energy savings than traditional white expanded polystyrene eps insulation.
Additionally eps is usually present in structured insulated panels.
Expanded polystyrene eps foam is a closed cell insulation that s manufactured by expanding a polystyrene polymer.
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.
Xps comes unfaced or with a number of different plastic facings.
Due to its physical properties xps has a higher r value than eps at 4 7 per inch.
O siding underlayment o pre cast wall panels.
Unfaced 1 in thick xps has a perm rating of around 1 making it semipermeable.

Ach foam technologies has made it easier for contractors and specifiers to see this with comparable features unavailable until now.
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.
Frank kiesecker has served as vice president sales and marketing architectural products for ach foam technologies since 2005.
Eps costs 10 to 30 less than xps per equivalent r value and compressive strength.
