Straightforward, durable prevention of weather damage with Ibstock's Chimney Caps. Wind, rain, ice and snow can all severely damage a chimney, especially sections located near to the top.
Chimney caps are therefore an essential part of building structures. They maintain the integrity of the chimney by eliminating moisture build up and accumulation of rainwater. Our Precast Concrete Chimney Caps are highly effective and last for many years with no maintenance required. At Ibstock we supply 4 way weathered Chimney Caps with drip grooves.
