PIR SANDWICH PANEL SUPPLIER SAUDI ARABIA, Packaging Type : SILVER

Surface finish types top & bottom sheet material types insulation types
corrugated mill finish aluminum polyisocyanurate (pir)
insulation specification
thermal conductivity value : amount of heat (w) passing through a material having surface of 1 m2 and thickness 1 m in order to rise temperature by 1oc . Units are wm k
k value (insulation value) : thermal conductivity divided by thickness of the material [ w m2 k]
u value (total insulation value) : also known as overall heat transfer coefficient determined by the insulation value of the various materials forming the panel . [ w m2 k ] , kcalm2 h oc , btu f t2 h of
on continuous system density k value
polyisocyanurate (pir) 40-45 kgm3 0.022 wm2k
please note : lower the k value , better is insulation capability
