Le porte parafiamma sono le più diffuse in Europa e nel mondo.
La loro caratterisitca essenziale è quella di soddisfare i requisiti di resistenza al fuoco richiesti dalle norme di sicurezza antincendi per gli edifici.
Con le nuove norme EN81-58 entrate in vigore in tutta Europa nel 2003 si è trovato un punto d'incontro sulla tipologia di prove a cui sottoporre i prototipi di porte di piano, andando così ad eliminare le incongruenze nelle specifiche delle porte determinate dalle autorità antincendio locali, generalmente diverse da nazione a nazione.
Sono disponibili 3 tipologie di classi:
Classe "E" (parafiamma)
Classe "EW" (parafiamma a limitato irraggiamento)
Classe "EI" (tagliafuoco)
Le porte di classe "EW", rappresentano una nuova cerificazione che va ad aggiungersi alla già ampia gamma di collaudi di cui Wittur dispone. Presentano le seguenti caratteristiche:
Utilizzo di lamiera in 15/10
Eliminazione di tutte le guarnizioni termo-espandibili
Eliminazione dei labirinti superiori e in battuta nelle antine
Esecuzione sempre rivestita (necessita cioè di un doppio strato di lamiera sia in caso di rivestimenti in inox o lamiera)
Varianti
Inoltre le porte di classe "EW" presentano un'elevata gamma di varianti:
Esecuzione saldata - se fattibile - o smontata
Installazione a filo muro o in nicchia al muro
Possibilità di utilizzo del calfeutrement
Installazione con stipiti parzialmente o completamente nascosti dietro il muro o in vista
Larghezza stipiti laterali variabile da 50 a 750 mm
Larghezza stipiti superiori variabile da 50 a 500 mm
Profondità stipiti laterali e superiore variabile da 30 a 100 mm
Sottosoglia standard o tipo Berlino
Soglia in alluminio, inox, ferro
Rotelle in plastica o in bronzo o in ferro
Possibilità di rinvio dell'emergenza sull'anta
