This genuine Schiedel Isokern Square Capping finishes DM44 block chimneys with a clean, weathertight top suited to render or brickwork installations, and it's rated for negative pressure (dry chimney) applications. Made from lightweight Leca concrete for easy handling and a good finish to the stack, it includes a drip tray designed to help prevent water ingress. As part of the wider Isokern pumice chimney system, it benefits from pumice's natural insulating properties — helping flue gases reach optimum temperature quickly and keeping the chimney warmer for longer, reducing condensation and soot build-up.
