Redundant/Dead

The Bonnet Cowl is recommended for use with redundant chimney systems and can be supplied with a birdguard mesh if required. The simple design helps to minimise rain entry into your flue preventing structural decay with potentially costly repairs in the long term.

The unit is available in our usual trio of colours (terracotta, buff and black) and is easily secured to your chimney pot with the use of a stainless steel strap. 

Stainless steel strap and fitting instructions included.

Rain entry into redundant chimneys is one of the main causes of structural decay to chimney stacks. The decay, caused by the natural freeze/thaw cycle of the weather, can ultimately cause great expense. Water works its way into the mortar between the brickwork and as it freezes, expands, eventually leading to cracks in the brickwork.

The Brewer Chimney Capper offers a simple solution at a low price that prevents rain, bird and debris entry while still allowing nominal ventilation.

Fixing kit included.
