Izola\u010dn\u00e9 vlastnosti striekanej peny zna\u010dne kol\u00ed\u0161u, kvalitu nikto nepreveruje.<\/strong><\/p>\n

V\u00a0prvom rade, pri striekanej pene je kvalita v\u00fdslednej izol\u00e1cie z\u00e1visl\u00e1 na mnoh\u00fdch faktoroch (teplota chemick\u00fdch komponentov, teplota a\u00a0vlhkos\u0165 vzduchu pri aplik\u00e1cii, teplota a vlhkos\u0165 povrchu kon\u0161trukcie, kvalita povrchu kon\u0161trukcie \u2013 prach, mastnota\u2026),\u00a0 ktor\u00e9 je mimoriadne n\u00e1ro\u010dn\u00e9 ovplyvni\u0165. K\u00a0tomu sa prid\u00e1va sp\u00f4sob aplik\u00e1cie, ktorej v\u00fdsledn\u00fd efekt v\u00fdrazne ovplyv\u0148uje mont\u00e1\u017enik. Tieto skuto\u010dnosti realiza\u010dn\u00e9 firmy nerie\u0161ia a v\u00a0praxi sa stret\u00e1vame so z\u00e1sadn\u00fdmi chybami striekanej PUR izol\u00e1cie a\u00a0s\u00a0nedostato\u010dn\u00fdmi izola\u010dn\u00fdmi vlastnos\u0165ami.<\/p>\n

Pri tradi\u010dn\u00fdch miner\u00e1lnych izol\u00e1ci\u00e1ch, ako aj pri fabricky vyr\u00e1ban\u00fdch PIR pen\u00e1ch podliehaj\u00fa kvalitat\u00edvne vlastnosti izol\u00e1cie pr\u00edsnej kontrole.

Kon\u0161trukcie zateplen\u00e9 tradi\u010dn\u00fdmi miner\u00e1lnymi izol\u00e1ciami alebo fabricky vyr\u00e1ban\u00fdmi PIR penami maj\u00fa deklarovan\u00e9 nielen tepeln\u00e9, ale aj protipo\u017eiarne,\u00a0akustick\u00e9 a\u00a0hlavne statick\u00e9 parametre, kde spr\u00e1vnym n\u00e1vrhom vrstiev kon\u0161trukcie predch\u00e1dzaj\u00fa kondenz\u00e1cii vlhkosti v\u00a0kon\u0161trukcii, a\u00a0tak br\u00e1nia tvorbe hniloby a\u00a0plesn\u00ed v\u00a0drevenom krove alebo stene.<\/p>\n

V\u00a0pr\u00edpade striekanej izol\u00e1cie ide o\u00a0polyuret\u00e1nov\u00fa (PUR) penu alebo \u00a0polyizokyanur\u00e1tov\u00fa (PIR) penu, ktor\u00e1 sa sklad\u00e1 z methylen diphenyl diisocyan\u00e1tu (MDI) a\u00a0tekut\u00e9ho polyhydroxylov\u00e9ho produktu obsahuj\u00faceho nape\u0148ovadlo (polyol). Jednotliv\u00e9 zlo\u017eky peny sa mie\u0161aj\u00fa priamo na stavbe, teda v\u00fdsledn\u00e1 kvalita je v\u00fdrazne ovplyvnen\u00e1 mont\u00e1\u017enikom. V\u00fdrobca nem\u00f4\u017ee u\u017e\u00edvate\u013eovi garantova\u0165 parametre ako v\u00a0pr\u00edpade tradi\u010dn\u00fdch izol\u00e1ci\u00ed, ke\u010f\u017ee dod\u00e1va len jednotliv\u00e9 chemik\u00e1lie. V\u00a0skratke, v\u00fdsledn\u00e9 izola\u010dn\u00e9 vlastnosti vznikaj\u00fa priamo na stavbe a\u00a0nikto detailne nepreveruje kvalitu a\u00a0vlastnosti takto zrealizovanej izol\u00e1cie. <\/strong><\/p>\n
