PIR board hi polyisocyanurate foam board tihna tawi a ni a, polyurethane (PU) hmanga siam insulation material siam that leh tihchangtlun a ni. Isocyanate leh polyols ratio siamrem a, meialh titawptu tha tak tak dah belh a nih chuan triazine ring structure nghet zawk a siam a, hei hian heat resistance leh flame retardancy-a tlangpuiin B1 flame-retardant standard a thleng thin a, meialh lakchhuah a nih veleh self-extinguishing, meikhu density hniam tak neiin, a titawp lo temperature sang takah awlsam taka tui tla thei. XPS extruded polystyrene board hlui nena khaikhin chuan PIR hian thickness inangah thermal conductivity a nei hniam zawk (a tlangpuiin 0.022W/(m·K) aia tlem emaw, a tlukpui emaw) a nei a, insulation efficiency a sang zawk a, kangmei laka invenna leh energy efficiency pahnih atana mamawh khauh tak scenario-ah pawh a tha zawk.
Ka in underfloor heating system atana insulation ka thlan lai khan duhthlan tur engemaw zat ka khaikhin a, a tawpah chuan he blue PIR board hi ka thlang ta a ni. A dah hnu chuan a nghet hlein a lang a, ke hnuaiah a tla lo va, a cut te chu a fai a, a chhe lo va, bang, underfloor heating pipe-ah te, cold storage atana base atan pawh a nghet tlat a ni.

Corner te tak te a hal chuan meikhu dum chauh a chhuah a, meikhu a curl up veleh a kang tawh lo. Building hlui pawn lam bang chhunga insulation-a hman a nih chuan thlasik laiin window vel condensation a veng a, thlasik laiin top floor-a stuffiness a veng bawk.
