Isokern Double Module DM54 300mm i/d Chimney Pack 7.8 Metres - Isokern

This 7.8m pack includes:

• 1 x 129031 DM54 Starter Flue Block for 300mm i/d
• 26 x 129033 DM54 Flue Block for 300mm i/d
• 26 x 130708 DM54 Square Casing 545mm
• 10 x 130771 Lip Glue 5kg
• 1 x 130696 Chimney Notice Plate

This pack is 7.8m of 300mm flue up to the underside of the capping. For a stove, add the 129043 DM54 300mm support block and the 129039 300mm stainless steel adaptor on this page.

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 300mm chimney pot or the DM54 raincap and top ring.

Lip Glue quantity is worked out from the Schiedel joints-per-bag chart (DM54: 4 casing joints per bag).

The Isokern Double Module DM54 300mm i/d chimney pack contains the pumice blocks and fixings to build a 7.8 metre high DM54 chimney with a 300mm internal diameter flue. The Isokern DM54 system is a self-supporting pumice block chimney: each 545mm square casing (300mm high) holds a round 300mm 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: 130733 DM54 670mm Square Capping for Render, or 130734 DM54 Square Capping for Brickwork with 130735 DM54 Square Corbel. Then choose your termination as an option: a 300mm terracotta or buff chimney pot (129035 / 129034) or the DM54 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 offset blocks can also be added on this page.

For a 7.8m flue this pack builds 26 courses: 26 casings (545mm square, each 300mm high) around 26 300mm flue blocks (26 x 300mm = 7.8m), plus the starter block and 10 bags of Lip Glue. It suits a DM54 chimney that needs 7.8m of 300mm flue above the firechest or stove connection you choose, up to the underside of the capping.
