Eps Vs Xps Under Siding

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

Eps vs xps under siding.

Eps costs 10 to 30 less than xps per equivalent r value and compressive strength. However eps insulation has proven to perform just as well in such situations. Polystyrene insulations eps and xps provider k 031 course eps 104 1 lu hsw sd. However the blowing agents used in the manufacturing process were known to deplete overtime reducing the insulation value.

Additionally eps is usually present in structured insulated panels. 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. In the past xps manufacturers were able to claim r values closer to 5 0 per inch. O standard 25.

O siding underlayment o pre cast wall panels. Due to its physical properties xps has a higher r value than eps at 4 7 per inch. Xps comes unfaced or with a number of different plastic facings. 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.

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. Expanded polystyrene eps foam is a closed cell insulation that s manufactured by expanding a polystyrene polymer. O expanded polystyrene eps is a durable rigid foam plastic material that is. Frank kiesecker has served as vice president sales and marketing architectural products for ach foam technologies since 2005.

Neopor can provide up to 20 more energy savings than traditional white expanded polystyrene eps insulation. 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.
