Negative pressure SLIM insulated chimneys

Insulated SLIM chimneys are independent chimney systems. Made of acid-resistant steel, they discharge smoke from heating devices operating under negative pressure. They include a 30 mm thick insulation which allows for installation outside the building. It is a proposition that meets the current market demand: a safe and durable chimney at an attractive price.
