Stabilità e durata nel tempo – Gli infissi in PVC mantengono inalterate le proprie prestazioni e le proprie caratteristiche for each lunghissimo tempo. La durata dei serramenti in PVC, la loro permeabilità, la sicurezza alla pioggia battente, la resistenza all’urto e allo scolorimento sono state provate da alcune ricerche effettuate da studiosi del settore che hanno tenuto gli infissi in PVC esposti agli agenti atmosferici for each ben 18 anni, non registrando mutamenti tali da pregiudicare le proprietà del materiale e l’idoneità d’uso.
