UPVC Sanitary is an alternative for painted wood. The hard polymer is ideally suited for producing strong plumbing pipes and fittings. UPVC is a low-maintenance building material used mostly for window frames and sills when installing double glazing in new structures or to replace existing single-glass windows. UPVC Sanitary is more durable than conventional PVC since it does not include BPA or phthalates. Because of this, uPVC is also frequently referred to as hard plastic. This may be used in a wide range of industrial applications.
