Selkirk announce new ventilation method

Selkirk announce an innovative new ventilation system that means that STC twin wall flue is the only flue in the UK that can be boxed in with non ventilated floor penetration components. Why do we care about that? Well the ventilated components allow the transmission of smoke (as well as noise, dust, smells, etc) and as far as we are concerned this is potentially dangerous as the room directly above a stove is usually a bedroom.
