About Us

Colt Cowls have been solving chimney problems since 1931 when the original Colt Cowl was first introduced. Since that time over 4 million Colt chimney cowls have been sold and successfully installed.

Colt Cowls have lead the market for the past 80+ years. Up until the 1980's the only anti downdraught cowl Colt Cowls produced was the original square Colt Cowl. However, during the 1980's partly in response to the increasing DFE (Decorative Fuel Effect) gas market, the Colt Top ALL PURPOSE was introduced as the first omni directional anti downdraught cowl. The Colt Top is still sold with the unconditional Money Back Guarantee the company is renowned for. Since the 1980's Colt Cowls have introduced many new products to the market and forged into new and different areas within the chimney industry.

The range today now includes a vast array of anti downdraught cowls, birdguards, revolving cowls, not to mention twin wall flue systems, vitreous enamel flue pipe, stainless steel flue pipe, flue and fireside accesories and flexible flue liner. The market leading range comes with the following benefits:

• Highest quality chimney cowls available

• Competitive prices

• Technical back up from expert sales team and over 80 years experience of making Colt Cowls
