The Firechests - Gather 800x440x215 (C16) by Isokern is the ideal solution for those seeking an efficient and easy-to-install fireplace component. Supplied as a flat pack, it can be swiftly constructed to create a neat, preformed fire opening ready for finishing. The unique insulating properties of pumice, a natural material, distinguish it from other chimney materials.
Pumice allows flue gases to reach their optimum temperature quickly, promoting superior performance of your heating appliance. Additionally, it keeps the chimney warmer for a longer period, reducing the risk of condensation and soot build-up.
