Security Chimney International


Security Chimneys International has kept the home fires burning for 50 years by researching and developing the hottest new ideas in residential chimneys and wood-burning fireplaces in today’s hearth markets. Each of our insulated chimneys, built for wood-burning, oil-fired and gas-fired appliances, gives you the peace of mind that they are made from high-quality stainless steel, features a 2″ safety clearance from all combustibles and comes with a lifetime limited warranty.


At Security Chimneys International, we’re never satisfied. We believe venting solutions can always be improved for our customers. Whether it’s making installations faster and simple or reducing overall costs while improving the quality, or enhancing technical support and customer service, we’re making it happen.

Our commitment to continual improvement is reflected in our growing commercial venting portfolio. We are continually raising the bar for quality, reliability, and ease of installation. We combine this with collaborative customer partnerships to ensure we are doing everything we can to provide the best solutions for your business.

Our expanding product lineup includes a variety of industrial-strength chimneys, all designed for Category I, II, III, and IV heating boilers, domestic water boilers, and low- to high-temperature hydronic heating applications.

All our Category II, III, and IV chimneys are made from laser-welded AL29-4C® type stainless steel to resist high temperatures and corrosion, making them ideal for high-condensation applications. And many of our products feature technologies that make installations quick and easy for you and your customers.
