This pack is 8.4m of 200mm flue up to the underside of the capping. Choose the connection on this page: the 130730 support block with a stainless steel adaptor for a stove, or the 130729 pumice gather with the 130820 Standard Firechest for an open fire.

The capping, chimney pot, top ring and raincap are not in the pack. Choose a capping for render or brickwork on this page, then either a 200mm chimney pot or the DM44 raincap and top ring.

Lip Glue quantity is worked out from the Schiedel joints-per-bag chart (DM44: 5 casing joints per bag).

The Isokern Double Module DM44 200mm i/d chimney pack contains the pumice blocks and fixings to build a 8.4 metre high DM44 chimney with a 200mm internal diameter flue. The Isokern DM44 system is a self-supporting pumice block chimney: each 440mm square casing (300mm high) holds a round 200mm flue block, and the casings and flue blocks are bonded with Isokern Lip Glue. A half-height starter flue block goes at the bottom so the flue and casing joints are staggered.

Not included: the chimney capping and the chimney termination. Choose your capping on this page: 130723 DM44 Capping for Render 570mm Square, or 130724 DM44 Capping for Brickwork 820mm Square with 130728 DM44 650mm Square Corbel. Then choose your termination as an option: a 200mm terracotta or buff chimney pot (127341 / 130697) or the DM44 Raincap & Top Ring. A chimney pot needs 38mm clearance to combustibles and is set into the capping and flaunched; a raincap and top ring on a straight rendered stack allows 0mm.

Extras such as offsets, flue entry kits, access blocks, wall ties and lintels can also be added on this page.

For an 8.4m flue this pack builds 28 courses: 28 casings (440mm square, each 300mm high) around 28 200mm flue blocks (28 x 300mm = 8.4m), plus the starter block and 9 bags of Lip Glue. It suits a DM44 chimney that needs 8.4m of 200mm flue above the firechest or stove connection you choose, up to the underside of the capping.
