Frequently Asked Questions

What type of installations is this cap compatible with?

This chimney cap is designed exclusively for flue gas evacuation systems with 200 mm double-walled ducts, and is fully compatible with pellet stoves, wood fireplaces, and biomass or gas boilers.

How does a double wall help improve the performance of a chimney?

The double-wall technology includes an insulating layer that maintains the temperature of the gases inside the flue. This prevents the smoke from cooling too quickly, drastically reducing condensation and improving chimney draft.

Is it weather and rust resistant?

Yes, it is made of premium quality stainless steel, a material especially suited to withstand continuous exposure to sun, rain, frost and corrosive combustion gases without rusting.

Can it be easily installed in an existing chimney?

The cap features a standard coupling system designed to facilitate quick and secure mounting on any 200 mm diameter double-walled tube.
