STYRO GRAYPOR (EPS)         XPS (Extruded Polystyrene)
STYRO GRAYPOR can be supplied up to from 5-1350mm  XPS can be made from 25-100 mm
Any length  up to 6 meters or width up to 1.35 meters is possible ONLY fix length and width is possible i.e 1250 x 600 mm
STYRO Graypor can be made from 14 to 35 kg/M3density 30 kg/M3 is the lowest density in case of XPS
Thermal conductivity (K value) @ 20.9 Kg/M3 : 0.0322 WmK Thermal conductivity K value @30 Kg/M3 : 0.032 Wmk
STYRO GRAYPOR is Compatable with Concrete & Brick works Smooth skin does allow concrete mortar to stick in
R value drift  : No change in R value till the life of the Insulation R value drift  : R-value deteriorate with the age of insulation
Since natural air is as insulating media Since injected gas is as insulating media
STYRO GRAYPOR is flexible board  therefore NO crack formation Since XPS is rigid board  there will crack formation
Due to expansion or contraction of building Especially with EIFS / ETICS Due to expansion or contraction of building Especially with EIFS / ETICS
Compressive property 150 kpa ( at 30 Kg/m3) Compressive property 210 kpa ( at 30 Kg/m3)

STYRO GRAYPOR is CFC , HCFC free ONLY CFC free NOT HCFC free
Ozone Depletion Potential ODP <0 ODP <0
Global Warming Potential GWP is : 0 Global Warming Potential GWP is : 1300

STYRO GRAYPOR is 15 % cheaper for the same  R value in relation with XPS
