Dunbrik (Dunfil) Chimney Infill Aggregate

Dunbrik A1 Concrete Flue Liner Systems are used in the construction of domestic chimneys, suitable for all types of domestic fires.

A domestic chimney is a structure made with a minimum of 100mm thick masonry, lined with purpose made flue liners.

Householders can burn any domestic fuel including coal and properly seasoned wood or install any domestic gas fire including flame effect fires.

Dunbrik A1 concrete flue liners outperform clay liners, are available for delivery to site within 3 working days and cost typically half the price.

Dunbrik concrete liners are made with tongue and socket joints for accurate location and tight jointing.

They are manufactured from kiln burnt aggregate and Portland cement and are designed to withstand repeated temperature fluctuations.

Flue liners should be joined with Dunseal fire proof mortar paste.

Allow approximately 3 joints per cartridge for 200mm liners, 2 joints for 250 & 300mm liners and 1 joint for 450mm liners.

Any void between flue liners and masonry surround should be filled with Dunfil insulating infill.

British Standard BS EN 1857:2003 established performance standards for concrete flue liners for domestic chimneys.

Dunbrik liners have been tested by BSRIA and achieved the highest categories in each class as follows: Dunbrik Type A1 - T600 N1 G D 3.
