Roccheggiani DP25 Black Twin Wall Flue Systems

Colt Cowls offer the very high quality sought after Italian twin wall flue system Roccheggiani DP25.

Regarded as one of the highest quality twin wall flue systems in Europe, Colt Cowls offer both the more popular black powder coated stainless steel system and the natural finish stainless steel.

Manufactured by Roccheggiani in Italy the DP25 double wall series is the leading product in Roccheggiani's range of flue systems. It can be used for a wide variety of purposes whether installing a traditional stove or modern high efficiency condensing appliance, the DP25 twin wall flue offers the ideal solution.

DP25 is a double wall system that can be installed both inside and outside thanks to an efficient thermal insulation system made of high density rock wool, which guarantees the optimal performance in all weather conditions.

The new flues are easy to install, weatherproof fully sealed components made to give uncompromisingly the best possible performance for both installation and use. The stainless steel (natural) range has been tested and approved to EN 1856-1 with the following designation T600 N1V2L50500 G50. The Black system has been recently tested and certified to T600 N1WV2L50040 G130.

The system is available in 5/6'' matt black and stainless steel finishes which come with a comprehensive warranty.

We advise using the natural finish stainless steel system for internal installations because the distance to combustible material is a lot lower at only 50mm. Matt black finish is more suitable for external installations where distance to combustible material is either non-existent or at greater distance. A combination of black and natural system can be used throughout a home where distnaces to combustible material are more relevant.
