Bodi ya povu ya XPS iliyoongezwa ina kiwango cha juu cha pore, upinzani mzuri wa mafuta, kiwango cha chini cha mafuta, uwiano wa chini wa upanuzi, insulation ya mafuta na kutoweza, ambayo inaweza kupunguza mzunguko wa hewa na upotezaji wa joto. Kwa hivyo, kuweka paneli za plastiki zilizoongezwa na maelezo yanayolingana na kiwango cha moto kwenye safu ya ukuta wa jengo inaweza kucheza athari nzuri ya insulation ya mafuta.
extruded plastic board is a closed cell structure, both compressive strength and thermal conductivity system is better than polystyrene board, the thermal conductivity of the extruded plastic board is less than or equal to 0.03, while the benzene board is less than or equal to 0.041, from this point of view can also be seen in the same thickness of extrusion board itself in the thermal insulation effect of the superiority of extrusion board, therefore, to do the roof, the Nyumba ya chini ya ardhi na runway na uhifadhi mwingine wa joto, kawaida hutumia bodi ya plastiki iliyoongezwa. Bodi ya plastiki iliyoongezwa kwa sasa inatumika zaidi katika mfumo wa insulation ya mafuta, ina faida za athari nzuri ya insulation ya mafuta, ujenzi rahisi. Kwa kweli, bodi ya plastiki iliyoongezwa inafaa kwa insulation ya paa (nguvu ya juu ya kushinikiza), insulation ya ndani ya kuta za nje (unene mwembamba, haichukui eneo la ndani).
