Traditionally, chimneys are constructed on site with separate components supplied by different manufacturers. This process is labour intensive and makes it difficult to ensure consistent insulation. By contrast the Lagan Chimney System offers modular, prefabricated units to speed construction and facilitate consistent quality standards.
The concept involves a modular 3-layer insulated chimney system:
1st Layer
A high quality rebated flue liner, made of fireclay, tested to EN1457.
2nd Layer
A flexible rockwool insulation of density 90kgs/m2 designed to maintain the temperature of the flue gases and allow them to pass freely up the chimney. It also allows the liner to expand and contract without damage.
3rd Layer
A lightweight aggregate chimney block which safely encases the entire system and provides additional insulation.
